Isabel Beach is a short run east of Flying Fish Cove along the Settlement shoreline. Curious Campers list it among the boat sites east of the cove, alongside Rocky Point, The Morgue and Coconut Point, and gazetteer data place the beach about 1.2 km north-east of Smith Point, below The Settlement's seafront along Gaze Road.

The Settlement coast has the same structure as Flying Fish Cove: a band of shallow fringing reef from the cliff and rock platform, then a coral slope that steepens into a drop-off. Nearby The Morgue has a shallow shelf of giant Acropora and feather stars sloping at about 35 degrees, and Isabel Beach is likely to be similar, with abundant hard coral and a rich community of reef fish – butterflyfish, angelfish including the endemic Christmas Island (Cocos) angelfish and hybrid butterflyfish, surgeonfish, triggerfish, wrasse and parrotfish. Turtles are common along this shoreline, and whitetip reef sharks and trevally patrol the edge.

Its main virtue is convenience: it is only minutes from the jetty, sheltered from the south-east trades and suitable for divers of all levels. Operators use such sites for short second dives or when the swell or wind rules out the longer runs west. Like the rest of the Settlement coast it is exposed to northerly swell in the wet season.

Data confidence is low; confirm details at the dive briefing. Divers wanting a similar and better-documented experience should ask for The Morgue.

Fly from Perth (about 4 hours, two to three flights a week, some via Cocos Islands) and hire a car – there is no public transport. Both dive centres are in The Settlement and launch their boats from the jetty/boat ramp at Flying Fish Cove, normally at about 8 am for a two-dive morning trip. From the cove the boat runs east out of the cove along the Settlement shoreline along the coast for roughly 2–5 minutes to Isabel Beach.

There is no land access to the dive, and the vertical sea cliffs mean no exit other than the boat. Operators choose sites on the morning according to swell and wind.

On the north-east corner of the island, off The Settlement. Sheltered from the south-east trade winds (roughly April/May–November), when it is usually calm, but exposed to northerly and north-westerly monsoon swell from about December to March/April; Extra Divers report February–April as peak swell season when boat diving is often cancelled. The corner catches currents that sweep around the island, so conditions can change within a single dive.

Visibility is normally 25–40 m, lower after heavy rain and during red crab spawning (October–January), which is also when whale sharks are most likely.

Descend on the reef edge, follow the slope with the drop-off on one side at 12–18 m, then return shallower along the reef top and finish at 5 m.
