On the West side of the island, overlooking Haro Strait and Vancouver Island, two public agencies provide trails through madrona forests that link up to complement one another:
Lime Kiln Point State Park, also known as Whale Watch Park (light green area at right) has a variety of walking trails, some moderate, some easy, and one leading to the whale watch overlook which is wheelchair accessible. Excellent displays about the nearby marine life and the former lime kiln operations, as well as a self-guided nature trail.
The San Juan County Land Banks Limekiln Preserve (dark green area at right) has trails connecting with those in the State Park, including a new trail going down to Deadman Bay and a smaller new trail making a loop next to West Side Lake. Other trails are really old roads from the days when the lime quarries and lime kilns were in operation. Follow short side trails into the old lime quarries.
