A very sheltered bolthole. For scale, this was taken from the deck of a 40-ft boat.

Riko Riko Cave on the Poor Knights Islands in New Zealand?

Riko Riko Cave on the Poor Knights Islands in New Zealand?

Very good. Rikoriko Cave , but right place.
Hadn't been there before. Feels weird sailing into a hole in an island and having 500 metres of rock above you.

How high is the cave roof?

There’s a similar hole on the Shiant Islands in the Minch but it’s tender territory not 40’ stuff

Yes, in the absence of any indication of scale, I wondered if it was the Shiants

There's a hole right through the Old Head of Kinsale, SW Ireland.

I very much doubt you'd get a tender through, but I've done it by sea kayak. If I remember correctly you have to get the tide right, and have to be careful as you approach the exit, especially at the western end, as the waves and swell can slam you against the roof.

How high is the cave roof?

35 metres.

It's nothing like that at the entrance. I took a look at it some years ago, but too rough to go in with the dinghy. The Poor Knights are riddled with caves and arches, a fascinating environment.

Still 20 metres plus at the entrance, but does get bigger once inside. Agree that the whole island group is a fascinating point of geology.
