The Mohegan Bluffs can be seen right at the southern part of the shore of Block Island. It measures a three mile stretch that is composed of coastal cliffs that comes with a 200 feet ocean drop. There can be no better beach than this and with its most pristine sand. This is one of the best reasons why many go to Rhode Island.

The entire Block Island is composed of stones and sands along with some piled up glaciers. The bluff reaches about 15 stories overhead and is the recipient of the strongest waves of the Atlantic waters. The boulders of granite that can be seen here are believed to have been pushed during the Ice Age which happened about 22,000 years ago.
