Lesser-Known Places in Estonia: 15 Special Places Worth Visiting at Least Once
When travelling in Estonia, you don’t always have to choose the best-known destinations. Viru raba, Taevaskoda, Rummu karjäär and Suur Munamägi are undoubtedly worth visiting, but there are also dozens of places that many people have never heard of.
In some places, mysterious caves await you; in others, a former military base, blue-green quarry channels or a forest dotted with dozens of lakes. There are also springs whose water appears to be a completely different colour from different angles, and historic ruins with a tragic love story behind them.
Below, you’ll find 15 little-known places in Estonia, suitable for a day trip, a family holiday or as part of a longer tour of Estonia.
Quick answer: what are the most fascinating little-known places in Estonia?
Hara allveelaevade baas, Saula Siniallikad, Käsmu kivikülv, Kuimetsa karstiala, Ungru lossi varemed, Tuhu matkarada, Kurisu neeluauk, Saxby tuletorn, Aidu karjäär, Kurtna järvestik, Poruni matkarada, Meenikunno raba, Viti matkarada, Helme koopad and Tindioru vesioinad are worth visiting.
1. Hara endine allveelaevade baas
📍 Address: Loksa metskond 134, Hara küla, Kuusalu vald, Harju maakond
🗺️ Open in Google Maps
Hara harbour, located on the Juminda Peninsula in Lahemaa National Park, looks like a scene from a Cold War film. Amid beautiful sea, forests and small coastal villages stand massive concrete structures that recall the area’s military past.
During the Soviet era, a secret naval base and demagnetisation station operated here. The hulls of ships and submarines were treated there to make them harder to detect with magnetic mines. Today, the decaying quays, concrete structures and sea form an exceptionally contrasting landscape.
Hara is ideal for history, architecture and photography enthusiasts. Guided tours are also available on site, during which visitors learn about the harbour’s former operations and everyday life at the military site.
Good to know: some of the old quays may be damaged and unfenced. Do not enter closed areas or structures at risk of collapse.
2. Saula Siniallikad
📍 Location: Saula küla, Kose vald, Harju maakond
📌 Coordinates: 59.215000, 25.042780
🗺️ Open in Google Maps
Saula Siniallikad are about a half-hour drive from Tallinn, but many people simply drive past them on the Tartu highway.
There are three main springs: Siniallikas, Mustallikas and Valgeallikas. Their water appears blue-green, brownish-black or greyish-blue, respectively. The different colours arise when light reflects off particles of sand moving along the spring bed through the clear water.
In Estonian folklore, springs were considered sacred, and their water was believed to have healing powers. Today, the main reasons to visit are the tranquillity, the unusual colour of the water and the mystical atmosphere.
A nature trail about 700 metres long leads from the car park to the springs. The site is open year-round, but the water may look most colourful in sunny weather.
Good to know: a forest path leads from the car park to the springs. Parts of the trail may be slippery after rain and in winter.
3. Käsmu kivikülv
📍 Trailhead: Laane tee 7, Käsmu küla, Haljala vald, Lääne-Viru maakond
📌 Coordinates: 59.602650, 25.917056
🗺️ Open in Google Maps
Käsmu is best known for its white houses, maritime museum and history as a captains' village. But hidden in the forest at the end of the village is a completely different attraction – an enormous boulder field.
Boulders of various sizes lie side by side across a large forest area, having arrived here with the continental glacier. According to Puhka Eestis, Käsmu kivikülv is considered the largest boulder field in Northern Europe. The largest boulder, Matsikivi, also known as Eremiit, on 4,8 metres kõrge ja selle ümbermõõt ulatub 14,7 metres.
You can explore Kivikülvi on the kilometre-long trail in Käsmu loodus- ja kultuuriloolisel matkarajal. Ligikaudu 4,2, which starts by the cable and offers an insight into both the history of the coastal village and the nature of the peninsula.
The best time to visit the boulder field is when there is no thick snow on the ground. The rocks can be slippery in rainy weather, so you should move carefully among them.
Good to know: wet and moss-covered rocks can be very slippery.
4. Kuimetsa karstiala
📍 Location: Iida küla, Rapla vald, Rapla maakond
🗺️ Open in Google Maps
The Kuimetsa karst area is a place where an entire underground world lies hidden beneath ordinary forest and grassland.
The area features sinkholes, subsidence valleys, depressions, channels and caves. Five caves are large enough for a person to walk into. This makes Kuimetsa one of Estonia's most diverse and interesting karst areas.
The area is especially fascinating during the spring floods, when some of the depressions fill with water and the landscape can change noticeably within a short time. In dry weather, however, the limestone formations and cave entrances are more visible.
Good to know: the ground is uneven and slippery in wet weather. Do not enter unfamiliar or narrow passages.
5. Ungru Castle ruins
📍 Location: Kiltsi küla, Haapsalu linn, Lääne maakond
🗺️ Open in Google Maps
In Kiltsi village near Haapsalu stand the ruins of a building with one of the most romantic yet saddest histories in Estonia.
Ungru Manor was designed as an almost exact copy of Merseburg Castle in Germany. According to legend, Count Ewald Adam Gustav Paul Constantin von Ungern-Sternberg had it built for a woman who did not wish to leave her home castle. However, construction was left unfinished after her death.
Although the castle was never fully completed, it is considered one of Estonia's most impressive Neo-Baroque buildings. The remaining walls, window openings and towers give an idea of how magnificent the building was intended to be.
The Ungru ruins make a good stop on the way to Haapsalu or Rohuküla harbour. Photographers usually find the most beautiful light here in the early morning or just before sunset.
Good to know: do not climb on the walls or go under unstable structures.
6. Tuhu matkarada
📍 Location: Kiska küla, Lääneranna vald, Pärnu maakond
📌 Coordinates: 58.567668, 23.824722
🗺️ Open in Google Maps
If Viru and Mukri bogs seem too crowded at the weekend, it is worth heading to Tuhu bog.
Tuhu hiking trail is only about 950 metres long and runs mainly along a boardwalk. This makes the trail a good choice for anyone who wants to see a bog landscape without undertaking a hike lasting several hours.
The trail leads through open bogland and offers an opportunity to observe how the vegetation, pools and colours of the landscape change with the seasons. It is particularly quiet here in the early morning or on weekday evenings.
Good to know: the boardwalk can be very slippery in wet weather, in frosty conditions and during winter.
7. Kurisu sinkhole on Hiiumaa
📍 Address: Sepa, Kurisu küla, Hiiumaa vald, Hiiu maakond
🗺️ Open in Google Maps
At first glance, the Kurisu sinkhole may not seem very dramatic on a dry summer day. During the spring floods, however, it can become one of Hiiumaa's most unusual natural phenomena.
This is a large karst sinkhole into which the stream from the Pihla bog disappears. The diameter of the sinkhole’s upper rim is approximately 32 meetrit ja sügavus 6,2 metres. During dry periods, the limestone bedrock and a small cave opening can be seen at the bottom. During high water, the sinkhole fills with water and resembles a temporary lake.
The water that disappeared underground resurfaces about three kilometres away near Pihla village.
Kurisu is a good stop on a tour of Hiiumaa, but the site is usually at its most impressive in spring or after an extended rainy period.
Best time to visit: the spring flood or the period following prolonged rainfall.
8. Saxby tuletorn on Vormsi
📍 Location: Saxby küla, Vormsi vald, Lääne maakond
🗺️ Open in Google Maps
Vormsi is off the route of many travellers in Estonia, which is precisely why the island has retained its special tranquillity and slow pace of life.
Saxby tuletorn, located on the island's west coast, was built in 1864. The white metal lighthouse stands on a rocky shore and offers a sweeping view of the sea and the sunset. The lighthouse's light is located at a height of 27 metres.
The lighthouse is open to visitors during the summer season, but it is also worth visiting the beach outside the season to walk among the junipers and enjoy views of Vormsi's western coast.
While on Vormsi, it is also worth visiting the island's cemetery with wheel crosses, the Rumpo Peninsula and the old coastal Swedish villages.
Good to know: access to the tower depends on the season. Also check the ferry schedule before your trip.
9. Aidu karjäär
📍 Location: Aidu-Nõmme küla, Lüganuse vald, Ida-Viru maakond
🗺️ Open in Google Maps
Aidu Quarry is a good example of how a former industrial landscape can become one of Estonia’s most distinctive adventure areas.
After mining ended, part of the quarry filled with water. Long channels of blue-green water now run between high limestone embankments. In some places, former roads disappear straight into the water, and trees and traces of the former mine can be seen beneath the surface.
Hiking trails cross the quarry area, and cable ferries have been installed to cross the canals. Guided hikes, canoe and raft trips, SUP tours and off-road safaris are also organised in the Aidu area.
Here, you need to be mindful of steep slopes, loose gravel and water depths that are difficult to assess. On your first visit, it is wise to use a marked route or go with a hiking guide.
Good to know: the area has steep slopes, loose gravel and deep water. On your first visit, choose a marked trail or a guided tour.

10. Kurtna järvestik
📍 Trailhead: Nõmmjärve car park, Vasavere Village, Alutaguse Municipality, Ida-Viru County
🗺️ Open in Google Maps
The Kurtna lake district may look like an unassuming forested area on the map of Estonia, but it contains an exceptionally large number of lakes.
An area of approximately 30 square kilometres contains around 42 lakes. One of the best ways to explore the area is the roughly nine-kilometre circular Kurtna hiking trail, from which you can see up to ten or eleven lakes.
The trail starts at the Nõmmjärve car park and passes through pine forests, hummocky terrain and areas around lakes of varying character. There are rest areas and campfire sites along the way, and in warm weather you can stop for a swim at some of the lakes.
Kurtna is ideal for those who want to see as much varied nature as possible on a single hike but prefer quieter forest trails to well-known bogs.
Good to know: allow several hours to complete the entire circuit, and bring drinking water and insect repellent.
11. Poruni matkarada
📍 Location: Kuningaküla, Alutaguse vald, Ida-Viru maakond
🗺️ Open in Google Maps
The Poruni hiking trail in Alutaguse National Park takes hikers through one of Estonia’s most pristine-looking forests.
The trail follows the bank of the Poruni River towards the Narva River and back. The area's value lies in its old broadleaf forests, riverside vegetation, and minimal human impact.
Poruni is not a typical well-maintained walking trail near a city. Here, you need to be prepared for roots, muddy ground, fallen trees and insects. In return, you can experience a tranquillity that is increasingly rare on more popular hiking trails.
Before setting out, it is worth checking the road and trail conditions, especially after storms or prolonged rain.
Good to know: the trail may have roots, mud, fallen trees and flooded sections.
12. Meenikunno Bog
📍 Location: Nohipalo küla, Räpina vald, Põlva maakond
🗺️ Open in Google Maps
Meenikunno is one of the most beautiful bogs in Southern Estonia, but compared with hiking trails near Tallinn, it receives far fewer casual visitors.
The bog has a boardwalk, an observation tower and hiking huts. Along the route, you can see bog pools, bog islands, sphagnum moss, wild rosemary, hare's-tail cottongrass and other typical wetland plants.
Meenikunno is particularly well suited to an early-morning outing. Mist, low sunlight and mirror-smooth bog pools make the landscape seem almost otherworldly.
When planning a longer hike, it is worth exploring the different trailheads, as both shorter walks and longer circuits can be combined in the area.
Best time: early morning, when mist lingers over the bog pools and the low sun reflects off the water.
13. Viti Lake hiking trail
📍 Address: Elva metskond 15, Ketneri küla, Nõo vald, Tartu maakond
🗺️ Open in Google Maps
The Viti järve matkarada near Elva differs from an ordinary flat forest trail due to its hilly terrain.
The route passes Lake Viti, a hiking hut, a campfire site, a picnic area and a 20-metre-high wooden observation tower. The tower does not offer a classic view of a city or bog—instead, hikers can see the forest canopy spreading out at different heights.
The trail is suitable for hikers of different ages, but due to slopes, roots and uneven terrain, it is not a good choice for navigating with a stroller.
Viti can be combined with a longer hike through the Elva ancient valley, during which you can see forest lakes, sandstone outcrops, floodplain meadows and beaver tracks.
Good to know: due to slopes, tree roots and uneven terrain, the trail is not well suited for strollers.
14. Helme koopad
📍 Location: Kirikuküla, Tõrva vald, Valga maakond
📌 Coordinates: 58.017776, 25.880556
🗺️ Open in Google Maps
The caves and the ruins of the Order's castle near Helme Manor Park form one of the most fascinating historical and natural complexes in Southern Estonia.
White sandstone is exposed in the caves. The caves were originally carved out by springs, but were later enlarged by people. It is believed that the caves were used as a refuge during wars. The system once consisted of seven interconnected chambers, the largest of which was called Moosese kirik. Some of the old passages have now collapsed.
Near the caves stand the ruins of Helme ordulinnus, dating from the 14 century. Thus, on a single trip, you can see caves, castle walls, a manor park and old legends.
Do not scratch anything into the sandstone walls, and do not enter closed passages due to the risk of collapse.
Good to know: do not scratch or write on the sandstone walls. Do not enter closed passages or those at risk of collapse.
15. Tindioru hydraulic rams
📍 Address: Tindioru, Tindi küla, Rõuge vald, Võru maakond
🗺️ Open in Google Maps
On Rõuge ürgoru matkarada, visitors will find a small but exceptionally interesting feat of engineering: Tindioru vesioinad.
A hydraulic ram is a water-powered pump that can pump water uphill without electricity or fuel. There are two of them in Tindiorg: the first was built in 1939 and the second in 2002. When spring water activates the system, the pump begins to make a distinctive rhythmic sound.
It is worth taking Rõuge ürgoru matkarada to reach Tindioru vesioinad. A visit to Ööbikuorg, Pesapuu vaatetorn, the lakes of Rõuge and the Eesti Ema monument can be planned for the same day.
This stop is particularly suitable for families with children, as it offers a simple, visual way to explain how the energy of water can power a mechanism.
Good to know: the valley slopes and stairs may be slippery in rainy weather.
When is the best time to visit lesser-known places in Estonia?
There is no single ideal time, as every season transforms these places differently.
In spring sinkholes, springs and karst areas filled by floodwaters are at their most impressive. Kurisu neeluauk and Kuimetsa karstiala may look most interesting at this time.
In summer it is easier to visit islands, lighthouses, longer hiking trails and water-related destinations. However, mosquitoes, ticks and, in some places, larger numbers of visitors must also be taken into account.
In autumn, Poruni old-growth forest, Viti’s hilly landscape, Kurtna lake district and Helme Manor Park become especially beautiful.
In winter Meenikunno bog or the area around Saula Siniallikad can be very photogenic, but boardwalks, steps and stones may be slippery.
What should you check before setting off?
Lesser-known places may not have a café, toilet, rubbish bin or reliable mobile coverage. Some roads may become difficult to pass after rain, and ferry connections to the islands depend on schedules and weather conditions.
Before setting off, check:
- the site's opening hours and any admission fees;
- the current condition of the hiking trail;
- parking and access conditions;
- the weather forecast and ferry or public transport schedule;
- movement restrictions in protected areas.
Bring a charged phone, drinking water, suitable footwear, and mosquito or tick repellent if necessary. If you are setting out on a longer trail, let someone know where you are going and when you expect to return.
Frequently asked questions
Which lesser-known places in Estonia are suitable for visiting with children?
Saula Siniallikad, Tindioru vesioinad, Käsmu kivikülv and the shorter Tuhu matkarada are well suited for visiting with children. Viti rada is exciting but inconvenient with a stroller. At Hara sadam, Aidu karjäär and near the caves, children must be supervised at all times.
Which places can be visited from Tallinn in one day?
Hara sadam, Saula Siniallikad, Käsmu kivikülv and Kuimetsa karstiala are suitable for a day trip from Tallinn. When combining several places, keep in mind that hiking and taking your time to look around usually take longer than they appear to on the map.
Where can you take the most unique photos?
Outstanding views are offered by the concrete structures at Hara, the colourful springs at Saula, the blue-green canals at Aidu, the ruins of Ungru Castle and the bog pools at Meenikunno.
Which places are suitable for visiting in autumn?
In autumn, it is worth choosing Poruni hiking trail, Kurtna lake district, Viti trail, Helme caves and the ruins of Ungru Castle. The colours of the leaves make the forest and park landscapes especially striking.
Are all the places mentioned free to visit?
Many natural attractions and hiking trails are free, but guided tours, harbour areas, lighthouses or visitor centres may charge a fee. Conditions may change, so check them on the site's official website before your trip.
Lesser-known Estonia is worth discovering
Lesser-known does not necessarily mean completely deserted or secret. Some places on this list are well known among locals but still remain undeservedly overshadowed by Estonia's more popular attractions.
The greatest value of these places lies not only in beautiful photographs. They show how diverse Estonia can be: here, old-growth forests, karst caves, industrial landscapes, coastal Swedish culture, wartime history and quietly recovering nature come together.
Start by choosing one area, leave enough free time in your schedule, and do not try to visit as many places as possible in a single day. The best discoveries usually happen when you do not have to keep checking the time.
