Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Stage Fort Park features two distinct dive entry points: Half Moon Beach and Cressy Beach, both offering easy sandy access from shore. Cressy Beach, in particular, is frequently utilized for dive training and events due to its predominantly sandy bottom, scattered with a few rocks.
Areas with marine observation appeal tend to cluster around closely spaced rocks sloping into the water. These are particularly to the left (east) of Cressy Beach's entry/exit point or to the right (south) of Half Moon Cove's entry. Depths remain shallow, generally reaching a maximum of 6 meters / 20 feet at high tide, though some of the most interesting rocky areas are only 3-4.5 meters / 10-15 feet deep.
Expansive seagrass beds characterize much of the site, alongside areas of varied marine vegetation, including tall eelgrass and fluffy red-pink blankets of plant life. Accessing the water often involves a walk of 137 to 229 meters (150 to 250 yards) over relatively flat ground from the parking area, making gear transport manageable.
A reliable alternative for training, this site proves useful when weather conditions impact other Cape Ann locations.
