Although there are scenic trails on both the refuge and town-owned portion of the island, the refuge does not currently provide public access to the island. The island is accessible by kayak or small boats (under appropriate weather and sea conditions). During the summer months the Thacher Island Association operates a boat out of Rockport. Contact the Association at Box 73, Rockport, MA 01966.
The Thacher Island self-guided interpretive trail brochure (pdf) highlights both the biological and cultural resources of the island. The brochure is also available from Parker River National Wildlife Refuge headquarters in Newburyport.
