Harakka Nature Centre operates in historical premises on the lovely island of Harakka, which has an unparalleled richness of vegetation and birds. At just a stone's throw away from Kaivopuisto, you are by the open sea, in the delicate nature of the archipelago.
We organise free nature tours, island adventures and public events during the summer season. The Nature Centre's facilities and exhibitions offer a great setting for visiting the island and getting to know the archipelago's nature. Some of the exhibition spaces are not fully accessible.

The heart of Harakka Nature Centre is the Nature House in an old renovated garrison building. Come and explore the Nature House's renewed archipelago nature exhibition and borrow research equipment for your excursion on the island. The Nature House is open to all, including during Nature School days.
Classes visiting the Harakka Nature School use the Nature House as a base camp for learning. Visit the Nature House and learn about the organisms in water samples. In the afternoons and weekends, microscopes are not in use by the Nature School. The Nature House has a lot of interesting things to explore for visitors of all ages. Plants of the island are also often on display.
The Harakka Nature Centre's office is located in the Nature House. When the staff of the Nature Centre is not guiding groups, you can usually find the employees near the Nature House.
The Nature House does not have a café. You can eat your own food at the groups of tables in front of the Nature House when the tables are not in use by groups from the nature center.
Fairy tale house Vellamo is a marine fairytale world, aimed especially for children. In Vellamo, you can get to know the life and experiences of the Baltic Sea through play. Dress up in sea creatures' costumes, stop by the sand goby's nest, colour photos of different species and rest for a moment by reading the books in the fairytale house. You can eat under the shelter of Vellamo’s porch.
Vellamo is open according to the Nature Centre's opening hours, from 10 a.m. to 5 p.m.
From the bird hide, you can observe the life in the surrounding water area. The bird hide is located right on the edge of the nature reserve, and is also a good observation spot for birdwatching in the spring. In the bird hide, there are information boards presenting the species in the area.
You can also visit the bird hide outside the Nature Centre's opening hours.
There is a photo exhibition in the Harakka bunker building: Harakka – Onnellisten saari (The Island of the Happy). The photo exhibition tells the colourful history of the Finnish Defence Forces' chemistry laboratory on the island. On top of the bunker, there is a birdwatching and landscape platform, which opens up a beautiful view of the sea and the surrounding archipelago. The platform is accessed by stairs.
You can also visit the bunker and birdwatching platform outside the Nature Centre's opening hours.
The Harakka campfire site is part of the facilities of the Nature Centre. You can heat your own food by the fire. Bring your own wood to the campfire site and take care when putting the fire out. Please carefully clean up after yourself and take your rubbish with you to the mainland.
Making a fire is strictly prohibited during wildfire warning. Check any active warnings in advance on the Finnish Meteorological Institute's website(Link leads to external service).
Please note that the nesting season of the birds continues intensely until Midsummer. Mother birds with nests near the campfire site must also be left in peace. You can ask the staff of the Nature Centre for more information on the use of the campfire site.
The casemates on the embankments of the island of Harakka are former ammunition warehouses. Some of the casemates are occasionally used as exhibition spaces for Harakka’s artists. Casemate III is a tunnel with a permanent photo exhibition by Visa Hietalahti, Meren sisäiset maisemat (Landscapes in the Sea).
Note! Casemate III is currently closed for safety reasons during the lighting renovation. Normally, casemate III is open according to the Nature Centre's opening hours, from 10 a.m. to 5 p.m.
The brackish aquariums in aquarium shed display the life of algae zones – fish, algae and crustaceans. The fish in the Gulf of Finland are also presented as life-size models. You can try angling with a fish game – which species did you catch? Aquarium shed is open according to the Nature Centre's opening hours, from 10 a.m. to 5 p.m.
During the spring season, aquarium shed often opens slightly later than the other facilities of the Nature Centre, as the brackish water aquariums are remade every spring.
A photo exhibition has been set up at the beach shelter next to the Harakka pier. The photographs tell about Harakka’s history, nature and the activities of the Nature Centre.
The beach shelter is also open outside the Nature Centre's opening hours.
Harakka is a nesting island for birds
During the bird nesting period 1.4.–15.8. Harakka’s southern end is closed. The nature reserve is marked off by a rope. During the nesting season, the birds defend their nests and young. Move around the island calmly and only along marked trails. From time to time, parts of the island's routes are closed and marked off with tape. You can talk to the staff of the Nature House in May–June before touring the island. In July, the mother birds are calm as their offspring have left the nest.
