Apart from the plethora of sea caves that Tony has mentioned and the sea caves with adits that Twiglet added, there's nothing apart from mines and Daniel Gumbs Cave near the Cheesewring Quarry, complete with mathematical symbols carved into the granite, but it's merely a chamber in boulders which is probably man-made anyway.  No limestone caves I'm afraid, or at least nothing more than maybe a couple of feet in the very far SE of the county where a bit of Devonian Limestone occurs.  However, I have been into a nameless sea cave which was difficult to access near Padstow which had a nice calcite flow in it.

And that's surely not a bona-fide caving club with a name like that is it Tony?

Naughty Tony!  I see a book looming ;) I am surprised you have left out the cave dive in Seal Hole at Prussia Cove covered in Martyn Farr's new book (plug plug).

Yes an e-book.  A free copy to anybody who send me details of a cave new to me, with NGR of course.

Maenporth Cave and Tunnel
SW 79017 29712
A nice natural sea cave with two entrances than intersects with a tunnel that goes back into the cliff. The natural cave runs parallel to the beach and involves a crawl. If heading east there is a step across a drop before reaching the crawl.
The tunnel forms the bottom of the step across and has a good stream that flows out a third entrance.

Seal Hole Cave, St Agnes, SW713512:   Entered via a short adit in the corner of the demolished harbour at Trevaunance Cove.  After a few feet step over a shallow hole in floor with short mine and part natural passages to right.  Over hole soon opens into impressive sea cave with two entrances about 200ft long where the tide hammers through.  Mine workings in cliff above are Seal Hole Mine, part of the Polberro group, accessible only by abseil and consisting of dangerous old stopes partly eroded by the sea.

Tea Cavern isn't the same as Cathedral Cave, they're adjacent to each other with a large colony of kittiwakes in the immediate vicinity so please keep clear during the breeding season to avoid disturbance.  Cathedral Cave is the one which was mostly destroyed by blasting as it was deemed to be a hazard to the tourists.

Levant Zawn SW368345:  An impressive rift sea cave 150ft high formed on the Main Lode of Levant Mine.  Access is possible via an engine shaft on the cliffs at the complex of buildings and leads down into the adit at the back of the zawn.  The sea cave is very difficult to enter otherwise; do not attempt to descend the old miners' path which zigzags down the cliffs as it has been eroded away partway down.  A huge pinnacle of rock detached itself from the main face at the cave mouth in about 2009.

There are literally thousands of sea caves, some very difficult of access but some suprisingly large. Many sites are shown on recent 1:2500 OS maps. Have surveyed quite a few. Cornwall Wildlife Trust may be worth contacting as someone probably through them has been surveying many which are used by seals.
A few to add to the list as a starter include Boatyard Hole (limestone), Empacombe Caves, SealHole Cavern (St Agnes), Towanroath Cavern (St Agnes) hessenford Cave (limestone) Pipers Hole (Tresco)

There's an interesting blow hole in the cliff at sea level just outside Boscastle harbour.
Not sure how far back or if there is a second entrance but it 'blows' on the rising waves entering the harbour & looks quite spectacular from the opposit cliff.

First many thanks to all the contributors.  The draft MSS is now 11 pages long.  If anybody wants a copy just email me and I can send it to you as an attachment.  I have yet to scan all the Explorer OS maps.  The ones I have looked at show numerous caves and ogos.

Fairly recent OS 1:2500 & 1:10000 maps which show sea caves available online on Oldmaps. Probably show much more than the Explorer series.

Hi Alasdair

Do you have NGRs for Boatyard Hole, Empacombe Caves and Hessenford Cave?

Regards - Tony

Hessenford Cave SX  3018 5658 this was explored by PCG & extended through a tight squeeze by a Craven PC member. Empacombe & Boatyard hole were fully described in PCG publications, the former I understand has been lost due to rubbish tipping.
Been trying to relocate a partial list of sea caves largely taken from OS maps but no success so far.

I had forgotten about Piper's Hole on Tresco and it was only 3 or 4 years ago that I visited it. Must be at least 50 metres long and is unusual in being an abandoned sea cave. An steep slippery boulder pile leads to a cold and noisome lake with a horrible squish mud floor (I did the trip in bare feet and bathing trunks!) that one can just about wade through along the left wall leading to a wide sandy beach then a low arch into another chamber then a continuing rift that gradually closes down. Well worth a visit. Very photogenic as well.

What an education.  I did not know that Tresco was in Cornwal.  Will add these coments to my e-book.

Despite what may have been said in the past, pETER g WILL BE CREDITED WITH HIS REMARkS.

Went to Newquay yesterday, a lovely little seaside town.  The man in the Tourist Office was very helpful and gave [!] me a map showing the locations of Cathedral Cave and Tea Cavern.  A photographic trip showed that we needed low tide for a visit.

Now my problem.  Can anyone located the following caves at Newquay: 

Blowing Hole,  Fern Cave, Great Bathing Cave, Pipers Hole, Porth Cave, Tea Caverns, and The Cavern?

The e-book is now 35 pages long.  Email me if you want a copy.  Surprisingly it is free   :o

Newquay won't be such a lovely seaside town soon - they're in the process of building about 3,000 new houses on prime agricultural land.  Our 5 minute walk into unspoilt countryside is going to be a thing of the past.

Fern Cave is often referred to as the rubbish-infested sizeable fossil sea cave above high tide between Tolcarne Beach and Lusty Glaze, a popular haunt for parties etc which sees a number of "rescues" each tourist season.
Pipers Hole I think was destroyed when the area around Headland Hotel was redeveloped, along with some features known as Fairy (or Pixies) Holes which were unique.
Porth cave is on the east side of Porth Beach and involves some easy scrambling at low tide to reach a short sea cave which runs parallel to the beach, notable for a few pyrite cubes and badly-preserved fossil corals (a rarety in these parts).
Blowing Hole is a bit further out towards the sea from Porth Cave and bisects Porth Island at a wide zawn and consists of a slippery rift.  When the tide comes in it can be quite impressive but would be very foolhardy to explore.
There is a second cave known as Tea Caverns at Whipsiderry, the next beach east of Porth, reached at low tide on the west side of the bay, a large but not very long sea cave.
I've not heard of Great Bathing Cave and The Cavern (the last could be just about anywhere) but I'll ask some of the older locals to see if they have a clue.

Ok Tony here you go, all NGRs prefixed with SW:

Fern Cave is at 819623
Pipers Hole 800624
Porth Cave 825629
Blowing Hole 824631
Tea Caverns (Whipsiderry) 828632

There's also some ancient iron workings which could be a couple of thousand years old which are located in Flory Island at 830633 and appear to be modified small sea caves which have eroded a siderite lode.  There are a couple of gated adits in the mainland immediately to the east, one of which goes for about 300ft but hasn't been stoped.  The other is much shorter.  They are locally reputed to connect to an obscured lead mine about a mile inland but obviously never did.
