Roadside lake in the Anacortes Community Forest Lands. People fish, swim, hike and bike here. Maybe horsies too. May be tainted by toxic algae in the summer months - check before you swim or let your dog swim.

Blanchard State Forest encompasses 4,500 acres and is home to multiple lakes, ponds, streams, mountains, overlooks, and running trails. Some paths are flatter and wider, while others are tight singletrack on the side of a mountain. This is a great place to come for a long run with all the trail and loop options.

This trail, a serene sojourn through a verdant forest, doubles as a rewarding cardio and leg workout with its unswerving ascent. The summit, however, grants a view that's nothing short of spectacular. Sugarloaf, a prominent peak in the Anacortes Community Forest, gifts you with reasonably splendid views of Mount Erie and the graceful expanse of Burrows Bay.
