Little Bay is a pocket beach tucked between the old Prince Henry Hospital site and The Coast Golf Club, and McFadyen calls the dive 'one of Sydney's easiest' – once you have got there. The logistics are the only obstacle: a walk behind the chapel, across a golf fairway behind the tee, and down a long flight of stairs to the sand, with a climb back that most people do in stages. The bay itself is 200 m long and 75 m wide with a shallow sandy bottom, and the dive proper starts at the mouth.

Exiting over the rocks and heading east you pick up a smallish wall on your right that drops through 5, 7 and 10 m with nice overhangs, a couple of swim-throughs and small gullies along the way. After about 25 minutes you reach the base of the rock platform of the northern headland, an interesting area of overhangs and small canyons. From there the sand can be followed north to the opposite side of the mouth and the reef followed back west into the bay, reaching 13 m on the sand in between.

Golf balls litter the whole site. Fish life is modest but pleasant: yellowtail, seapike and sweep in the deeper water, luderick and eastern rock blackfish in the overhangs near shore, and the usual leatherjackets and wrasse. There is a tap on the eastern wall of the old building near the tennis court for rinsing gear, and the golf club bistro above has what McFadyen reckons is the best view of any club in Sydney.

For new divers, snorkellers and anyone wanting a quiet, protected dive in the south-eastern suburbs on a flat day, Little Bay is ideal; the neighbouring 4th Hole inlet on the same golf course is the more adventurous option.

From Anzac Parade or Bunnerong Road turn into Little Bay Road and follow it to the chapel car park at the old Prince Henry Hospital site (now residential; parking is limited and signed). Walk behind the chapel, cross the golf course behind the tee – quietly, and watch for golf balls – and descend the long staircase to the beach; it is a 300–400 m walk with a steep climb back that needs rest stops. Enter from the main beach in the centre of the bay and exit the same way.

The Coast Golf Club car park is an alternative start.

The bay faces east and is shallow, so it needs fairly flat seas – under about 1 m of east or south-east swell – or the mouth becomes a break zone; inside the bay itself is sheltered in most conditions and fine for snorkelling. Westerly and north-easterly winds are no problem. Tide has little effect.

Visibility is ordinary (5–12 m) and drops after rain. Summer heat makes the stairs and golf-course walk in a wetsuit hard work, so early morning or cooler months are better.

Cross the bay at right angles to the sand ripples to the mouth, go out over the rocks heading east and pick up the small wall on your right; follow it as the depth goes 5, 7, 10 m past the overhangs, two swim-throughs and small gullies to the rock platform area (about 25 minutes), then follow the sand north to the opposite side and return west along the reef to the bay.

Abyss Scuba Diving and Sydney Dive Academy occasionally run training or night dives; mostly independent divers.
