The Honeycombs are a lesser-known part of the Canal Rocks area. Marinelife.org.au describes a limestone reef - a large outcrop cut into a series of ledges and caves - in about 6 m, reached by an energetic 400 m swim north-east along the shore from the Canal Rocks boat ramp. It advises watching for boats and displaying a dive flag, and notes stingrays aggregating near the ramps.

The name reflects the pitted, cave-riddled limestone, a contrast to the granite canals nearby. Ledges and caves in shallow water shelter wrasse, bream and old wives, and western rock lobster may be found in the cracks. The shallow depth gives long bottom times, but the swim in and out needs to be factored into gas and energy planning.

The site suits fit, experienced shore divers on flat days, or divers with a small boat. It is a pleasant alternative when the main Canal Rocks reefs are too exposed, although the swim itself is exposed to swell. Published detail is limited, so depths and position are indicative.

The stingrays near the boat ramp are a bonus at the start and end of the dive; watch them from a respectful distance and do not touch or feed them.

The Capes coast between Cape Naturaliste and Cape Leeuwin faces the Indian Ocean and is famous for its surf, which is exactly what makes diving here so condition-dependent. Long-period south-westerly groundswell can arrive on calm, sunny days, and the regional ocean-safety guide advises observing a site in different conditions before diving it, never diving alone and flying a flag near boat ramps.

Park at the Canal Rocks car park and boat ramp (Canal Rocks Road, about 6 km south of Yallingup). Enter near the ramp and make an energetic 400 m swim north-east along the shoreline, towing a float and flag. A small boat launched at the ramp makes access easier.

The nearest full-service dive shop for fills and hire is Swan Dive in Busselton; there is no dedicated dive shop in Margaret River or Augusta, so bring filled cylinders.

Only in low swell with easterly winds; the swim along the shore is exposed to swell and surge. Boats use the nearby ramp. General pattern on the Capes and Leeuwin coast: summer mornings often have light easterly (offshore) winds before a south-westerly sea breeze, and long-period south-westerly groundswell can arrive on otherwise calm days; winter fronts bring big swell and north-westerly winds.

Check the Bureau of Meteorology swell forecast, not just the wind.

Swim 400 m north-east from the ramp, descend at the limestone outcrop and explore its ledges and caves at 4-6 m, then swim back along the shore. Snorkellers should stay within easy reach of the exit point and swim with a buddy; scuba divers at these depths need no safety stop but should ascend slowly and surface near the float.

No operator; self-guided by experienced local divers. Nearest dive services: Swan Dive (Busselton/Port Geographe) for fills, hire, nitrox and charters; no dive shop in Margaret River or Augusta.
