As a major tourist destination, most every Cape Cod town has many sites of interest which are within the town pages. Some of the attractions of a regional nature are:
The Bass River is the longest all salt water river on the East Coast and nearly bisects Cape Cod. This Yarmouth and Dennis landmark is beautiful in its own right and has great spots for boating, kayaking, fishing and watersports. You can even take a narrated cruise (http://www.capecodkayakin...)
