Are there any sea caves or caves that meet the sea on the East coast?

The Northumberland and Durham coast seems to be made of limestone.

There also seems to be limestone on the west coast around Lancaster. Any caves there?

there are certainly some mines along the coast of the North Yorkshire Moors

Flamborough Head (Yorkshire - E coast) has lots of sea caves. 'Adventure sports' outfits run canoe trips round there.

Limestone area around Arnside (N of Lancaster) has a lot of caves marked on the OS map.

There is the The Marsden Grotto pub in a cave, but yes there is a lot of limestone south of the Tyne but TBH I don`t know much about it  :-[

The northumberland / durham coast is limestone - in places - but its very low, and certainly around the north sheilds/southsheilds areas - I have never seen any evidence of what you would call caves.

What about the pembroke area - the only one I know is the one taken by the climbing route 'Perposterous Tales' at bosherston head - this is on the MOD range, so  public some of the time.

St Govan's Cave, reached by abseil or scary climb, has a chamber with an impressive stal column (pub)
Wogan's Cave (fossil sea cave under Pembroke Castle). (priv)

 Paul it's nice to hear your recollections of your Grandad taking you off on explorations of those seacaves, From your discription;Blacksomthing in the NE of England, I would think they could be Blackhall Rocks Caves. NGR NZ 473389 These are formed in a wide band of the cavernous Magnesium Limestone, they are impressive as you say. If we have relocated these caves of your youth, in many years time(?) you too can continue a fine family tradition!.

Thanks for the info.

A well know (to this forum) amature geologist reliably informed me that there were no caves in the Magnesium Limestone.  :spank:

IIRC it's Magnesian Limestone & there are plenty of caves in it. Some very well known archaeological sites to begin with.

How many years have you got? With Britain's fractal coastline you are also going to have the challenge of deciding what is significant as a cave. I know some quite complex sea caves on the South Devon coast that are in metamorphosed shale but they are longer than some limestone sea caves and more complex. Then you have caves/mines such as the complex system at Trevaunance Cove near St. Agnes in Cornwall. Have fun!

Beachy Head Cave is in chalk, not limestone.

Chalk is Limestone!!  :read:

Oh no it isnt.


Chalk is Cretaceous Limestone, a fine grained porous rock formed from the remains of planktonic organisms

Are you dealing with the UK covering (in alphabetical order) England, Northern Ireland, Scotland, Wales plus of course the Isle of Man etc?  Or just one of them? 

Oldham's Caves of Scotland does moderately well for sea caves but it will require a substantial search to dig them out of the text.  Not sure how he deals with access control as it has historically not been much of a problem in Scotland.

I am afraid I can't resist asking the Cave Registry Coordinator what about cave registry info?  Or is this a hole in its UK coverage? 

Also, can any one search online the OS map stock for sea caves?  I have no idea if this is a stupid question.

Regarding Staffa, all its sea caves have "controlled" access under National Trust for Scotland delegated to various boat operators who take you out there.  It is a SSSI for caves as well as birds flora and gelology, etc.

I've got a Tony Oldham book titled "caves of scotland" which contains details of a number of sea caves from Wemyss bay up to here on Skye. If these are any use I'll  post some grid references.

The GSG database currently has 1128 entries for seacaves around Scottish coasts (including Orkney and Shetland)
Judging by the fact that only 141 of these have a length recorded (on this database), most of them appear to be unsurveyed.

I have been checking out seacaves on the E coast between Arbroath & Peterhead and on the adjacent N coast, and have done rough surveys of some of them.
My tally of confirmed seacaves on the E coast is sitting at 112 of which 9 are over 100 m total tunnel length and one of those is 270 m.  Most, but certainly not all, are indicated on various versions of OS - with the 1st Ed 6" generally the most informative - doubtless reflecting a much greater interest in, and local knowledge of, the coastline by small boat fishermen in the nineteenth century.
The caves are in sandstone, sandstone conglomerate, granite and one in basalt.
