About this site
Cathedral Rocks lies along the Massachusetts coast north of Boston, in the waters off Cape Ann. This stretch of rocky New England shoreline is typical of the granite ledges and boulder fields found along that part of the Atlantic coast. The dive itself is shallow, reaching a maximum depth of around 4.6 metres, but it is rated advanced.
