Caeau Tan y Bwlch

Caeau Tan y Bwlch ("the fields below the mountain pass") on the northern slopes of Bwlch Mawr represent some of the last unimproved fields left on the Lleyn Peninsula with clawdd (earth and stone) walls still in place. The meadows are grazed from September to April each year. Some of the drier meadows are cut for hay in late summer.
