Bass Creek may be viewed from the GJK Viewpoint boardwalk at Grays Beach.
It’s a lovely walk on a boardwalk over a salt marsh that terminates in a small seating area. The walk out is great; you pass over schools of tiny fish, plenty of fiddler crabs, and a beautiful ecosystem up close. The seating area has a dynamite view of the surrounding sand bars and the inlet that leads to Grays Beach. A must see if you enjoy Cape Cod for its nature and beauty.
The AllTrails website has a description and map of a hike at Bass Creek using the Grays Beach Boardwalk.
