The biggest and busiest town on the Lleyn, Pwllheli has been a port and market town for centuries. It was given its charter as a borough by the Black Prince in 1355, and a street market is still held each Wednesday in the Maes. The inner harbour has silted up, but the outer harbour provides berths for a few fishing boats and increasing numbers of yachts and sailing dinghies. The South Beach is a long strip of sand, backed by shingle, while the Glan-y-don beach, east of the harbour, has almost 4 miles of sand, with safe bathing, except near to the harbour mouth and the Gimlet Rock. The sands stretch eastwards to the sheltering headland of Pen-y-chain, skirting the secluded village of Abererch which has cafes, shops and a car park.
