Underwater directions: Entry/exit the water on a steep slope and descend to the left and you will come to a small cliff, follow the bottom of the cliff till it reaches 30m and turns left. You are now at the bottom, follow the bottom of the cliff and large boulders till you come to a broken shell slope upwards, (should take 10 mins). Here is where you turn back and ascend diagonally to 15m and follow the tops of the large rocks, which can have large groups of plumose anemones on top of them. Keep heading back to the exit point until the large boulders change to a steep shingle slope, here is where you exit the water. There is a big rock at the water's edge which is good to sit on to remove your fins.

Site Hazards: Fast cars on A814, Depth, Darkness (this can be a spooky dive) the entry/exit can be difficult through the tunnel and down to the water.

Dive reports: Stew 28/4/07 dived the caves today. i was sitting at 17m next to a fisherman's crude mooring (rock & rope) & i could see the buoy on the surface. fantastic viz, never dived this site since last November? & never seen it this good for a long time. no sign of Beryl the seal although we did swim through the odd mushroom cluster of low viz (<1m). perhaps she was around! a great day out with really nice weather. 

Dive reports: John 22/5/09  there were plenty of sea cucumbers and plumose anemones. Murphy's law kicked in because we saw two big yarrells blennys and no camera. We went a good bit past the small pinnacles at 29m and came back at 17m slowly ascending to 10m to wash off the 13mins deco. There were plenty of goldsinnies but no saith. Normally there are a few saith above the plumose anemonies at the start of the dive but none tonight. I was waiting for the seal that normally buzzes you here to turn up as there were no big fish. A good dive and the apree dive was at the Village Inn. 

Dive reports:  PhoebeSparke  Saturday 27th October 2012  Forecast snow hadn't arrived thus the trek down under the culvert was as good as it gets. Also, a lack of recent rain meant that there was no peat runoff. I've done this dive before but only with trainees and limited depth. This year diving with a newly qualified Sport's Diver allowed me free rein. We ducked under and made our way the gravelly slope to about 25m. Although we'd taken our torches, it was still fairly light at this depth. Fantastic boulders covered in sea loch anemones, yellow fluted sea squirts and peacock worms. Long-legged squatties and leopard-spotted gobies seemed to inhabit every crevice. Water temperature was a pleasant 12 degrees and visibility about 10m. After a recent thread on Finstrokes, I was aware to keep my eyes open for the fishing line but we were lucky this time - none apparent. Making our way back up the slope was also interesting. Lots of dragonets, burrowing anemones and sand gobies. As we off-gassed at 6m, we poked about the sugar kelp unearthing strawberry worms and more yellow fluted sea squirts.
