Showing 1–24 of 30

Canoe Beach (Nahant)

Massachusetts · 3–10.7 m

Canoe Beach is one of the North Shore's most popular shore dives: a pebble beach at the head of a small cove on Nahant's east side, next to Northeastern University's Marine Science Center. The bottom slopes gently to about 30-35 ft, and in the middle of the cove a series of rock pinnacles - the 'chimneys' - rises from the bottom to break the surface at low tide, with a famous swim-through that divers enter from the side and exit out the top. Visibility is variable, best after calm westerly winds. Parking is the main obstacle, as the lot is restricted to Nahant residents.

Shore entry 5.0 (1)

(Approximately 65 ft long steel fishing trawler) Wreck

Massachusetts · Up to 27.4 m

An unnamed steel stern trawler of roughly 65 ft rests on top of Stellwagen Bank in just over 30 m of water, inside the outbound Boston shipping lane that crosses the national marine sanctuary. Decades on the bottom have split the wreck apart: the pilothouse stands upright with helm, throttle, and radio gear still visible, while the hull and stern lie separately near a lone trawl net reel, with patches of blue and white paint still clinging to the steel. NOAA and a local dive charter installed a subsurface mooring here, and divers visiting the site are helping investigate the wreck's still-unsolved identity.

IntermediateBoat entry

Back Beach

Massachusetts · 3–9.1 m

Back Beach in downtown Rockport is the region's quintessential training and night-dive site: metered parking beside the sand, a rock-free walk-in entry, and a forgiving 10-30 ft bottom. By day it hosts a steady parade of open-water classes; by night divers come for sea ravens, flounder, skates and the squid that swarm dive lights in season. Visibility is typical New England — 20+ ft on a good day, under 10 ft after a blow.

Shore entry

Cathedral Rocks

Massachusetts · 6–24.4 m

Cathedral Rocks is an advanced shore dive off the granite cliffs of Pigeon Cove, Rockport, reached by climbing down jagged rocks to a slab entry. Straight out the bottom drops to about 80 ft, with boulder ledges left and right famous for large lobsters, anemone-covered rock and gamefish. Conditions must be near perfect: ocean swell makes the climb-out dangerous, so it is dived far less often than neighboring beaches.

AdvancedShore entry

Corporation Beach

Massachusetts · 1.5–6.1 m

Corporation Beach in Dennis is widely regarded as Cape Cod's best shore dive: a classic white-sand Cape Cod Bay beach with a rock jetty at its left end. The dive area outside the jetty is a mix of medium rocks, boulders, sand, and eelgrass beds in no more than about 20 ft of water, and the bright sand bottom often gives the site unusually good visibility. Restrooms and a seasonal snack bar make it a good spot to bring non-diving family. Best dived within an hour of high tide on days without northerly wind.

Shore entry

Dartmouth artificial reef

Massachusetts · Up to 9.1 m

Artificial reef built from Concrete

Boat entry

Folly Cove

Massachusetts · 3–24.4 m

Folly Cove, straddling the Gloucester/Rockport line on Cape Ann's north shore, is widely regarded as the area's premier shore dive. A cobble beach between two long rocky points leads to a sheer west wall — the 'great wall' — carpeted with frilled anemones and dropping toward 70-80 ft at the left point, while the cove's sandy center holds skates and flounder. It is dived day and night year-round; the only real frictions are slippery low-tide rocks and resident-only parking at the landing.

IntermediateShore entry

Garbage Beach

Massachusetts · 1.5–21.3 m

Garbage Beach - officially Woods Hole Waterfront Park - is a well-known local dive in Woods Hole Harbor, Falmouth: a small lawn and pocket beach next to the Marine Biological Laboratory piers. Divers enter from the beach stairs or giant-stride off the second MBL pier into an eelgrass meadow with depths from about 5 ft near shore to as much as 70 ft at high tide farther out. The site must be dived around high slack water because Woods Hole's tidal currents are powerful, and harbor boat traffic is heavy in season. Visibility is typically modest, but the eelgrass and pilings hold abundant invertebrate and fish life.

IntermediateShore entry

Harborview Beach

Massachusetts · 1.5–6.1 m

Harborview Beach, beside the Sesuit Harbor breakwater in Dennis, is an easy, shallow Cape Cod Bay shore dive and a favorite quick dusk or night dive for locals. Navigation is simple - keep the breakwater on your right and pick through the rocks for lobsters, crabs, and other critters. Most of the dive is around 10 ft at high tide with a maximum of about 15-20 ft at the end of the breakwater, making it a great beginner site. Dive within an hour of high tide and watch for fishermen on the rocks and boat traffic in the harbor channel.

Shore entry

Harwich reef

Massachusetts · Up to 10.1 m

Artificial reef built from Concrete

Boat entry

Hathaway Pond

Massachusetts · 1.5–17.4 m

Hathaway's Pond is a 20-acre freshwater kettle pond in Barnstable considered one of the best training sites in New England, with a maximum depth of about 57 ft. Attractions include a wooden training platform at roughly 20 ft about 70 ft off the swim beach, a 35-ft cabin cruiser (the Field & Sea, sunk in 1979) at about 30 ft, and a sunken car. With no current and easy beach entry it hosts certification classes year-round and serves as the standard fallback when Cape Cod ocean sites are blown out. The pond is stocked with trout and also holds bass, perch, sunfish, and catfish.

Shore entry

HEROIC (91 ft long wooden eastern rig dragger) Wreck

Massachusetts · Up to 30.5 m

Heroic, a 97-ft wooden-hulled former U.S. Navy coastal minesweeper (USS Heroic, AMc-84) converted to a Gloucester eastern-rig dragger, caught fire and sank on 21 August 1969 atop Stellwagen Bank. The wreck rests in about 100 feet of water with its large Atlas diesel engine surrounded by hull sections, trawl winch, and anchor chain, much of it draped in old nets. It is an official NOAA-listed sanctuary dive site with a subsurface mooring installed in partnership with Northern Atlantic Dive Expeditions.

AdvancedBoat entry

Herring Cove Beach

Massachusetts · 3–6.1 m

Herring Cove Beach in Provincetown, part of the Cape Cod National Seashore, is a calm west-facing shore dive over a gently sloping sand bottom bordered by rocky stretches and patches of eelgrass, with depths of roughly 10-20 ft close to shore. It is best known for snorkeling and easy diving on bottom dwellers like crabs, lobsters, flounder, and sea robins, and locals rate it as one of the best night dive spots in the area. Strong tidal currents run offshore toward Race Point, so divers should stay within the cove. Visibility of 30-40 ft is possible around slack high tide.

Shore entry

HubLine Boston Harbor

Massachusetts · Up to 7.9 m

Artificial reef built from Rocks

Boat entry

JOSEPHINE MARIE (90 ft long steel fishing trawler) Wreck

Massachusetts · Up to 32 m

The Josephine Marie, an 80-ft steel-hulled stern trawler built in 1969, sank on 1 February 1992 while fishing Massachusetts Bay. The red-and-black-hulled wreck lies upside down in 105 feet of water on the southern end of Stellwagen Bank with its bow facing roughly southeast; the exposed propellers are a favorite photo spot. An official NOAA sanctuary dive site, it carries swift currents and draped fishing gear, so dives are timed to slack water.

AdvancedBoat entry

Magnolia Rocks (Kettle Cove)

Massachusetts · 4.6–15.2 m

Magnolia Rocks (at Kettle Cove in Gloucester's Magnolia village) is a long granite ledge sloping into the sea, fronting a sand bottom strewn with medium and large boulders that run several hundred yards offshore. The boulder field shelters abundant lobsters and fish life, but the bare ledge entry is fully exposed to southerly swell and is considered one of the most hazardous entries/exits on Cape Ann — strictly a calm-day site for experienced divers.

AdvancedShore entry

Morton Park - Little Pond

Massachusetts · 1.5–15.5 m

Little Pond in Plymouth's Morton Park is a sheltered freshwater kettle pond used by local divers as an easy training and gear-shakeout site, especially when the ocean is rough. Average depth is about 19 ft with a maximum around 51 ft, over a very silty bottom with vegetation, rocks, and sunken logs that shelter freshwater fish. The pond is a coldwater pond stocked regularly with rainbow trout. Best dived off-season, since the town beach draws crowds and parking fees after Memorial Day.

Shore entry

Niles Beach

Massachusetts · 3–7.6 m

Niles Beach sits inside Gloucester Harbor on Eastern Point, giving it some of the most protected water on Cape Ann. The gradually sloping sandy bottom only reaches about 15-25 ft, so it serves mainly as a training venue and a reliable backup when ocean-facing sites are blown out. Summer parking requires a Gloucester resident beach sticker, though walk-on access is open to all.

Shore entry

NORTH STAR (55 ft long wooden eastern rig dragger) Wreck

Massachusetts · Up to 25.6 m

The North Star was a 55-foot wooden eastern rig dragger built in 1967 in Portland, Maine, that fished out of Gloucester until it capsized on August 28, 2003, when an overloaded clam dredge rolled the vessel; both crew members were rescued by a nearby fishing boat. The wreck lies in about 100 feet of water on the northern end of Stellwagen Bank in three scattered sections: the hull, a clam dredge roughly 100 feet away, and deck machinery still linked to the dredge by towing cable. NOAA's Stellwagen Bank National Marine Sanctuary once maintained a dive mooring here, but the site has since been heavily damaged and displaced by scallop fishing gear and is no longer maintained as a recreational dive site.

IntermediateBoat entry

Old Garden Beach

Massachusetts · 3–15.2 m

Old Garden Beach is one of Cape Ann's classic, most-dived shore sites, a small Rockport neighborhood beach with a ramp down to the water and an easy sand entry. A 100+ yard swim out leads to kelp-covered boulder fields in 20-40 ft, with several distinct dives possible depending on heading and a max depth around 40-50 ft. It is a prime open-water training site and can be very crowded on summer weekends.

Shore entry

Pebble Beach (Rockport)

Massachusetts · 3–10.7 m

Pebble Beach on Penzance Road is one of Cape Ann's most popular backup shore dives, prized for free roadside parking and shelter from northerly seas. A roughly 150-yard swim over sloping sand and gravel reaches a band of grassy, kelp-fringed boulders parallel to the beach, with depths topping out around 25-35 ft. Easy conditions make it well suited to new divers, though waves can complicate the loose-pebble entry.

Shore entry

Pinthis Wreck

Massachusetts · Up to 32 m

The Pinthis, a 206-ft steel coastal tanker, was rammed by the passenger liner Fairfax in dense fog on 10 June 1930 and sank in flames with all 19 crew lost. She lies turtled (upside down) in roughly 100-105 feet of water off Scituate on a rock-and-sand bottom that often yields 30 ft+ visibility, with several interior chambers accessible to trained wreck divers. It is one of the South Shore's classic advanced boat dives.

AdvancedBoat entry

Plum Cove

Massachusetts · 3–6.1 m

Plum Cove is a small, well-protected neighborhood beach in the Lanesville section of Gloucester with clear, shallow water of 10-20 ft and one of the easiest entries on Cape Ann. A small rocky reef lies just outside the cove off the right-hand point, and the sheltered, gradually sloping bottom makes it a favorite for training, night dives and bail-out days. The main constraint is summer parking, which is restricted to Gloucester beach-sticker holders during the day.

Shore entry

Sculpin Ledge Channel

Massachusetts · Up to 7 m

A dive site in United States. The site reaches a maximum depth of about 7 m. The site is reached by boat.
