Double-decker cave

This cave has an upper, supratidal chamber facing NNW above a lower chamber which is upper intertidal. The ceiling/floor between them is set back under the overhang above the top chamber. The lower chamber faces about N and swings right as you go in. It is fairly wide all the way to its end. At the entrance 11m wide.

High up on the E side of the entrance, there is a second, much smaller entrance separated from the main entrance by a small, roundish pillar. This entrance opens into the upper chamber.

by land. Go to Clashach Cove in the lower 1/3 of tide, via the coastal path from Hopeman harbour, or via the Clashach Quarry track E of Hopeman (limited parking). Then go through the subterranous passage to access the foreshore.

Photo 1 shows it near high water.
Photo 2 a portrait view of the upper and lower tunnel entrances from the beach/wave-cut platform. Taken on 21 Nov 20 - as are the following.
Photo 3 a landscape view of the same - showing the curving shallow channels on the surface of the wave-cut platform.
Photo 4 the small rift tunnel on the left (E) side of the lower, sea-level, entrance.
Photo 5 round the corner inside the lower tunnel - with floodlight.
Photo 6 looking out from inside the lower tunnel - about NNE.
Photo 7 taken on 17 Nov 21 looking roughly SW from the rocky ledge at the E side of the main entrance. The pillar is a bit left of centre with the upper part of the upper entrance visible over the grass.
Photo 8 shows the pillar and the upper entrance from closer to. The following photos were taken sitting in the 'saddle' of that entrance.
Photo 9 looks across the edge of the upper chamber. The floor of that chamber goes up steeply at 35 - 40 degrees and is covered in a sand/something green mix which holds itself in place, but offers no secure foothold. On the right below is the floor of the cave's lower deck or chamber.
Photo 10 is a pan to the left from photo 9. It shows much of the upper chamber, but not the part behind the pillar on the left - which remained unseen- because there was not an obvious safe way of getting to it.
Photo 11 looking right and up. This was taken for the tiny pillar near the centre which looks a bit like a handle.
