Massachusetts dive guide with visibility and wildlife notes for Magnolia Rocks.
Challenging Cape Ann shore dive with lobstering and rock ledges.
Challenging Cape Ann shore dive with lobstering and rock ledges.
Magnolia Rocks is a challenging Gloucester shore dive with a rocky ledge, boulders, and crevasses that make the underwater terrain interesting once you clear the entry. The site is best on calm, high-tide days with very light N/NW wind, because swells can build quickly and the entry and exit can turn from awkward to serious in a short time. Lobsters are a big draw, and other cold-water fish move through the ledges and cracks.

Depth range, seasonality, and planning context.
Reported Depth
4.5m - 12.2m
Depth Note
Descriptions cluster around roughly 15-40 feet, with the ledge sloping to boulders and sand.
Best Season
High tide on calm days, especially with very low N/NW wind in summer.
Typical Conditions
A rocky ledge slopes gradually into the water, and swells can build quickly enough to change the dive.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
The entry can become dangerous when swells build, and the site can change from manageable to rough within a single dive window. Stay patient, watch the sets, and only enter when the conditions are truly calm.
Access Restrictions
Resident-only parking is used near the site, and the direct entrance in front of the intersection should be avoided because of local access-right concerns.
Legal Notes
Respect the designated public access route and local parking rules. Do not block residential access when gearing up or exiting.
Community notes to help plan your visit.
Scuba Diving
Best treated as an experienced shore dive with a careful surface plan and a willingness to abort if the sets build.
Freediving
Only for confident freedivers on exceptionally calm days; the site is much better suited to scuba.
Snorkeling
Snorkeling is limited by the rocky entry and changing swell; it is not a casual beach snorkel.
