Best for Solitude

Mohegan Bluffs,

Block Island, Rhode Island

But privacy always comes with a price. In this case, it's getting here. For the most scenic experience, take an hour-long ferry from Point Judith or New London, Connecticut, to Block Island, pick up a bike in Old Harbor, ride three miles south, and then walk down the wooden stairs to the beach. Here the surf is always strong, the sand dotted with driftwood and sea glass.

Sea Glass in Massachusetts:

Sea Glass has not been easy to find this year. I find the Fall and Winter Months are best. Gloucester and mid Maine beaches usually fair well for beachcombers. See http://www.tearsofthesea.com/ for Sea Glass Hunting Tips. Good Luck.
