Our starting point will be Skyline Marina in Anacortes, where hikers will board a boat which will take us to Decatur Island.  This boat is operated by the Decatur Northwest Homeowners' Association and provides transportation for residents and their guests for a fee. In 2015, the roundtrip fare for each guest is $35, payable by check only upon boarding.

Carpooling is strongly recommended to reach Skyline Marina, which is 85 miles from downtown Seattle. The marina is southwest of the Anacortes Ferry Terminal and is located at 2011 Skyline Way, Anacortes. Additional details will be provided to participants before the hike.

The meeting time at the marina will be 9:00 a.m.  


This is the latest hike in the Island Hike Series coordinated by Kathy Biever and Julie Miller. Our destination is Decatur Island, one of the San Juan Islands, and one that is rarely visited by the general public since it is not served by state ferries. Our local expert and guide, Bev Corwin, is a homeowner on the island and has obtained permission from the land managers to help lead this hike for the Mountaineers.  Our group size is limited to 15.

After taking the Decatur Northwest boat from Skyline Marina in Anacortes, we'll arrive at Sylvan Cove. Our 7-mile hike will take us to notable gardens, an airfield, White Cliff, a country store, and a one-room schoolhouse.  We'll head to the top of Sheep Hill to take in spectacular views of Decatur Island, Center Island, and Kimball Preserve (a nature preserve).

Please bring snacks, water, and a packed lunch to enjoy on the hike.
