The Paavola Oak is a protected ancient oak tree in Lohja, Finland, known for being one of the largest and oldest oaks in the country. Standing approximately 20 meters tall with a trunk circumference of nearly 7 meters, the tree is estimated to be several hundred years old. It serves as the primary landmark of the Paavola Nature Trail, a forested route that winds through protected groves. The tree's massive canopy and gnarled branches have made it a site of regional cultural significance and a frequent destination for nature enthusiasts. The surrounding area is part of a nature reserve, preserving a biodiversity-rich habitat including diverse lichen and fungus species.
Position yourself at the base of the trail incline directly facing the trunk to capture the full scale of the canopy against the sky.
Wear waterproof hiking boots, as the trail can become muddy and slippery after rainfall.
Carry mosquito repellent during the summer months, as the forested area is prone to insect activity.
Stay on the marked paths to protect the delicate root system of the tree and the surrounding forest floor.
Do not attempt to park on the narrow shoulder of Pietiläntie; use the designated parking area at the start of the trail.
Do not climb on the tree or touch its bark to prevent further stress to the aging wood; carry out all trash.
