One cannot leave the openings in the sandstone unexplored.
It looks as if around HW is the best time for entering the caves.
Iain had thought of bivouacing inside in September, so the landslide was this winter. It would have been scary to be inside as the hill above slumped down. Check out Iain's post for more details of this stretch of coast.
All that remained was to fetch the car. Perrymans has an hourly bus service along this coast, nearest stop to Pease Bay; about 30 minutes walk at Cockburnspath. The buses are often late according to fellow travellers, so don't worry if it seems a bit tight to catch the bus. However, they soon make up time, the bus ride a thrill in itself. Cheaper than a single fairground ride and it lasts longer!
We camped at High View/ Drone Hill campsite with its plethora of type 27 pillboxes. Just the ticket for the pillbox enthusiast. Even for us, the top of the pillboxes was a refuge from the midges. Good views of the wind farm as well. The place has mixed reviews on the web, we can say we found it cheap, comfortable, well equipped and very friendly.
