Branford Trolley Trail This easy trail walk goes through marsh between Tilcon parking lot and Stony Creek center. The out-and-back trail covers 1.3 miles and takes about 0.5–1 hour to complete. The popular, level multi-use trail offers great views of Stoney Creek and the Thimble Islands, where you can keep an eye out for fiddler crabs. The trail offers a mix of natural beauty with markers of an industrial past, most strikingly an old trestle bridge. The trail follows a track that was active from 1907 to 1937, the extension of a 1900 line from New Haven to Branford that continued to run until 1947.
