Koivuluoto is a rock island measuring about half a square kilometre, in the outer archipelago of Hamina, conveniently located halfway along the route of about six nautical miles between Kilpisaari and Ulko-Tammio.
The island’s rocky shore makes access difficult, especially for larger boats. However, a couple of metres of beach has been cleared of stones on the northeastern shore of the island, where you can find an open wilderness hut and a place to secure your boat with stern-to mooring.
Koivuluoto is one of the national park’s two excursion islands that have an open wilderness hut for backpackers. The building previously served as a rescue station for a sea rescue club. The wilderness hut has beds, mattresses and pillows for eight people, a table and benches, a gas stove, a wood stove and a stove for heating. Backpackers can stay in the hut for two nights at a time, and after that, make room for others who need a place to sleep. The other, small red cottages in the northern tip of the island are supply sheds for fishermen, not to be used by backpackers.
There is a campfire site and a dry toilet in the yard area of the open wilderness hut in the northeast corner of the island, near the north shore. The island also has two other campfire sites.
