Boyd's Tower is a sandstone tower built in 1847 on Red Point, the southern headland of Twofold Bay, by the entrepreneur Benjamin Boyd. Intended as a lighthouse, it was never lit and was used instead as a lookout by shore-based whalers, who watched from it for whales and signalled to the boats. It is now a landmark of Beowa National Park.

The reef below Red Point is part of the same coastline as the documented sites nearby: the scuttled tugs Tasman Hauler and Henry Bolte lie just to the south on sand at 25–30 m, and Jacko's Cave at Leatherjacket Point shows the character of the reef – walls, boulders and caves covered in brilliant sponges, sea squirts, gorgonians and lace coral, with nudibranchs, octopus, cuttlefish, eastern blue devilfish and leatherjackets. The red rocks that give the point its name continue underwater as boulders and ledges.

The reef is best seen as an adjunct to the tug dives, and divers visiting the wrecks may be able to spend a dive exploring it. Its history is the draw: humpback whales still pass the point every spring, and the Eden Killer Whale Museum tells the story of whalers working alongside orcas in Twofold Bay. The museum in Eden is worth a visit on any non-diving day.

Boat access only. Local boats launch at the four-lane Quarantine Bay ramp 3 km south of Eden (toilets, cleaning tables, trailer parking) or from Snug Cove in the town harbour and run south across Twofold Bay. Red Point, topped by the sandstone Boyd's Tower (1847), is about 10 minutes south of Eden across Twofold Bay, and the Tasman Hauler and Henry Bolte lie just south of it.

By road, Boyd's Tower is reached via Edrom Road and the Boyds Tower access road in Beowa National Park, but the cliffs make shore diving impractical.

Red Point is the outer southern headland of Twofold Bay. Its northern (bay) side is sheltered from southerly swell, but its seaward face takes easterly and southerly swell. The tugs just south of the point are dived in most winds, so the bay side of the reef should be similar.

Visibility is often good, as on the Tasman Hauler.

Anchor on the bay side of Red Point and follow the reef along the base of the cliffs, returning shallower. Combine with a dive on the Tasman Hauler or Henry Bolte nearby. Keep the cliff on one side for navigation and ascend on the anchor line.

No operator lists a separate Boyds Tower reef dive; Eden operators (Merimbula Divers Lodge, Dive Eden) dive the adjacent tugs and could include the reef.
