Pwllheli is a small town with several cafés, pubs and restaurants, as well as a big supermarket (Asda), long sandy beach, promenade and marina. In terms of tourism, Pwllheli is mostly overshadowed by nearby towns like Abersoch, Criccieth, and Porthmadog. However it offers plenty for people passing through or wanting a place for the night, and I feel the beach is very worthy of a detour!

Nefyn is a beautiful little north coast seaside village with harbour, museum and a graceful sandy crescent beach. The Llyn Maritime Museum tells the story of the peninsula’s often stormy relationship with the sea.
