Snug Cove is Eden's harbour, home to the fishing fleet, the fishermen's co-op, cafés and, more recently, a wharf used by cruise ships. It has long been used for wharf diving, and Dive Eden lists wharf dives among its Twofold Bay offerings, while Sapphire Coast Scuba guides dives at the nearby Cannery Wharf (Cattle Bay) and other Eden shore sites.

Wharf pylons and harbour rubble in temperate NSW are rich macro habitats: sponges, ascidians, hydroids and mussels cover the pylons and attract nudibranchs, sea hares, shrimps, crabs and pipefish. Seahorses, weedy sea dragons, octopus, cuttlefish, stingrays and fiddler rays are common finds at Sapphire Coast wharves such as Merimbula. Fish include bream, luderick, leatherjackets, trevally and schools of baitfish, and seals sometimes visit the fishing fleet looking for scraps. At night the pylons come alive with crustaceans, octopus and squid.

The site suits macro photographers and night divers, preferably with a local guide who knows which areas are permitted and safe. The key issues are boat traffic and fishing lines in an active port. Eden is also a whale-watching centre in spring, and humpbacks sometimes enter Twofold Bay close to the harbour, so keep an eye out on surface intervals. After the dive, the fishermen's co-op and cafés are a few steps away, and the Killer Whale Museum up the hill is one of the best regional museums in NSW.

In Eden, follow Imlay Street to the Main Street roundabout and descend Main Street to Snug Cove, where there is parking near the wharves, the fishermen's co-op and cafés. Entry points and permission to dive near the working wharves should be checked with Dive Eden or Sapphire Coast Scuba (both based in Eden), who run guided wharf dives. Keep clear of the fishing fleet and the cruise-ship wharf.

Snug Cove is on the northern side of Twofold Bay and sheltered from southerly swell; strong easterly swell entering the bay can surge around the wharves. Visibility is variable – better in settled westerly weather and poorer after rain or when fishing boats are moving. It is a good night dive in calm conditions.

With a local guide, enter at an approved point and work slowly along the wharf pylons and rubble at 3–8 m looking for macro life, staying away from boat berths and moving vessels. Return the way you came.

Dive Eden lists wharf dives in Twofold Bay; Sapphire Coast Scuba guides Eden wharf dives (Cannery Wharf, Ross's Bay, Shelly's Beach). Local divers use the harbour for night and macro dives.
