Mount Erie: Sugerloaf & Heart Lake

Hike through wooded forest areas reaching the highest point on Fidalgo Island at Mount Erie. After enjoying the commanding views of the San Juan Islands, continue down the lightly traveled road to the trailhead leading to Sugarloaf. Enjoy the views from Sugarloaf, then continue downhill, completing the hike with a loop around Heart Lake.


From Northbound I-5 take Exit 230 and follow State Route 20 west for 11.7 miles to the junction with SR 20-spur into Anacortes.  Continue left on SR 20, after 1.8 miles turn right onto Campbell Lake Road. Drive 1.5 miles and bear right onto Heart Lake Road. Continue 1.5 miles and turn right at a sign indicating "Mt. Erie Viewpoint." Proceed 200 feet to the trailhead.

On the trail

Following well marked trails, hike through the lovely forest to the summit at Mount Erie. The views from Mount Erie are spectacular, so plan on spending some time relaxing and enjoying the scenery. Descend the paved road to the junction of the Sugarloaf trailhead, then ascend to the second highest summit on Fidalgo Island. Enjoy the views from here before descending and connecting with the trail around Heart Lake.
