So its going to be quality not quantity for a bit, and this is pure Quality!
The sunny seaside town of Benllech on Ynys Mon is home to a nice beach, some sport routes and this lovely cave....
South of hidden wall, this 40ft deep cave has a nicely flared horizontal chimney running through its entire roof at head height. The rear of the cave is fairly cramped and non descript, but a couple of yards towards the light a chockstone marks a sensible starting point. From here, jamming, back-and-footing, and general squirming will get you to the light and here...
For the highball topout. There is a couple of downsides to this amazing discovery (and why I didn't snap it up when I found it)
-Tidal; needs a fairly low tide.
-Holds damp; will require a good coastal breeze, and as the crack goes all the way, some dry days. a Towel might help too.
-Landing is bouldery; probably solved by 2 mats stacked on a leash and a spotter to drag it.
There we go. Please report back.
