There's a small restriction at Burbage North but which covers a couple of relatively popular routes.
It covers from Crystal Tips (E3 6a) to The Sentinel (E2 5b), which includes the popular Black Slab (VS 4b).
I put signs up this morning - it will only run for two weeks as the chicks were hatching today. This is (most likely) the second brood of a pair which nested successfully a little further along the crag last month.
