You can go ashore here at the small county dock near the little island at the bay's south side, and at two public beaches on the eastern and northern sides of the bay. You can't go ashore at Parks Bay, as the beaches and uplands adjoining the pretty bay on the western shore of Shaw Island are all private. A great place to watch the sunrise is Aleck Bay on Lopez' south shore. Anchor well back in the bay, where it's about 24 feet at low tide with a mud bottom. If it's clear, climb out of your bunk at sunrise and enjoy the view east to the Cascades over your morning cup of joe.
Uplands are private.
The aptly named Sylvan Cove offers room for about six boats in 12 to 30 feet of water. It is located at Decatur Island's northwest shoulder, at Lopez Sound. Uplands are private, but anyone can enjoy the greenery from an anchored boat.
