The Paavola Nature Trail runs through a protected oak grove on Lohjansaari Island in Lohja. Along this approximately one-kilometer-long trail, visitors can explore the deciduous forest, rocky outcrops, and stream banks with the help of 15 informational signs. The trail also leads to the famous Paavola Oak. The trailhead and parking are located in the courtyard of the former Lohjansaari school at Pietiläntie 23. You should allow about an hour to complete the trail. The trail is not accessible to people with disabilities, and some of the structures are in poor condition. Boardwalks and clay soil may be slippery when wet. Choose footwear suitable for the terrain and adjust your pace according to the conditions; the trail is not maintained in winter. This is a self-guided outdoor excursion. You can inquire about up-to-date trail information at the Lohja Tourist Information Office.
