Crayfish Bay offers a compact reef system with canyons and caverns worth exploring from shore, all within 10 metres of the surface. The cavern and canyon features are the real draw here, creating interesting swim-throughs and sheltered pockets where crayfish tuck into crevices alongside starfish and various reef fish. Visibility is variable, so conditions can swing considerably between dives. A moderate to strong current runs through the site, and surge inside the overhead environments demands solid buoyancy control and situational awareness. Pick your entry timing carefully, as rip currents are a genuine hazard. Best visited from late spring through summer and into autumn.

Check the swell forecast closely before committing to the cavern sections, as surge can make the overhead environment unpredictable even on days that look calm from the surface. Parking is available on site, so arriving early on calmer mornings gives you the best shot at manageable conditions.
Access is via the Great Ocean Walk from the Cape Otway Lighthouse, or from a small car park at the end of a dirt track off Blanket Bay Road. A short walk is required from the car park to the beach.
The bay is moderately safe close to shore at low tide, but strong currents exist further out and near the channels leading to the open ocean. The area can be subject to stormy and windy conditions.
