Pebbly Beach is one of the best-known beaches on the NSW South Coast, mostly because eastern grey kangaroos graze on the grass behind it and wander onto the sand. It lies in Murramarang National Park about 20 km north of Batemans Bay, at the end of an unsealed road, and it has a small NPWS campground. It is included here because it is a named snorkelling and easy diving location on the Durras–Murramarang coast, but it is not documented as a scuba site by any of the regional dive directories.

The beach is flanked by headlands with shallow rocky reef. Under the water, expect kelp and crayweed, boulders, sand gutters and patches of seagrass rather than dramatic walls. Fish include blue groper, luderick, eastern rock blackfish, sweep, leatherjackets, wrasse and bream, with stingrays on the sand and octopus and nudibranchs in the rocks. As part of the Batemans Marine Park the fish are generally less wary than on heavily fished coast.

The site suits snorkellers, families and new divers on calm days. It is a pleasant break during a weekend of boat diving at Batemans Bay or a camping trip. It is not a place for deep or technical diving. Check the current park and marine park rules before collecting or fishing. The drive in is slow and unsealed, so allow extra time, and bring everything you need because there are no shops at the beach.

From Batemans Bay drive about 10 km north on the Princes Highway and turn right onto Mt Agony Road, then follow the unsealed Pebbly Beach Road through Murramarang National Park to the beach (about 25–30 minutes; park entry fee applies). Park in the day-use area behind the beach, then walk across the sand. Snorkellers and divers usually swim to the rocky reef at the southern or northern headland.

A small NPWS campground and amenities are beside the beach.

The beach faces east and is exposed to swell from the north-east through south-east, so it is only suitable for diving or snorkelling on calm days with less than about 1 m of swell. North-easterly afternoon winds in summer chop it up. Visibility falls after rain.

Morning is usually the calmest time.

Enter from the beach near one headland and follow the reef edge along the rocks at 3–8 m, keeping the rocks on your shoulder for navigation. Turn at half gas and return along a shallower line to the beach, surfacing in the lee of the headland.

No dive operator runs trips here; it is visited independently by campers and snorkellers. Nearest dive services are Beneath the Bay in Batemans Bay.
