May 22, 2025, Karkali Strict Nature Reserve Boardwalk

Beautiful hike through one of the most diverse forests in Southern Finland. This is a strict nature reserve, so unlike national parks and other nature reserves, you must stay on the path, and you are not allowed to pick anything - not even berries or mushrooms!

I have rarely seen a forest in Finland with so many hazelnut bushes.

Very beautiful wooden bridge, which is currently (summer 2024) being renovated and is not accessible by wheelchair.

Warning: At certain times of the year, blue-green algae can develop on Finnish beaches. It is advisable to ask locals beforehand whether there are blue-green algae. If so, swimming with children or animals is not recommended and a shower for adults is highly recommended. A mass proliferation of cyanobacteria can greatly reduce water quality and significantly limit the use of the water. The bacteria produce a variety of secondary metabolites that act as allelochemicals, antibiotics, hormones and toxins and can harm fish and zooplankton, for example. Some of the toxins are among the most powerful natural poisons and can also be dangerous to humans and land animals. Bathers can develop allergic skin reactions and inflammation. Swallowing water containing cyanobacteria can also cause stomach and intestinal infections.

The loggia itself was sturdy and in a nice location. There was a beach on the beach where you could have lunch. And despite the rocky shore, the boaters were also remembered with buoys. The only bigger minus came from the pier that was lifted onto the beach and broken by ice. It would be a great addition to this excursion site intact.

The Karkali Nature Reserve, located in Karjalohja, is approximately 100 hectares in size and was established in 1964 to protect. the preservation of rare forest flora and fauna in Finland. The area has been protected primarily for the complete protection of nature and scientific research, but unlike nature parks in general, Karkali is also open to hikers. Since the area's sensitive nature does not easily withstand the wear and tear caused by hiking, the park and its attractions are only allowed to be accessed via signposted trails. So please do not deviate from the trails!

Along the two-kilometer-long Hanski-Hakki trail you will find information boards that give you an insight into the surrounding nature.
