So Many Options!
Despite being relatively small (in the grand scheme of things) Sucia Island is the biggest of the three outer Shan Juan Islands and provides many different options for visitors. I often bring small groups of kids to Sucia when I lead trips.
Fox Cove and Shallow Bay are my favorites. Fox Cove is on the southwest side of the island and one of the smallest coves that has mooring and camping sites. Shallow Bay is the second largest cove on Sucia, there are group camping sites, multiple nice beaches and lots of camp site options. The northern beach of Shallow Bay is sandy, warm water and home to the China Caves. The Caves are fun to climb around in and have a fun history of hiding smugglers. There are also only several hundred feet between Shallow Bay and Echo Bay which means you can easily carry kayaks across rather than paddle around the island. The space between Shallow and Echo also has a large group campsite area complete with a picnic shelter.
Sucia also boasts fun fossils in and around Fossil Bay. There are lots of fun hiking trails and roads around the island as well as interpretive signs. The Finger Islands in Echo Bay are fun to paddle around. Also, the absolute best phosphorescence I have ever seen in my life were in Echo Bay.
