A great café at Pwllheli railway station

Porthmadog is simply a busy hub, a gateway to the Llyn Peninsula and Snowdonia National Park. It is a lovely harbour town with a gorgeous mountain backdrop. It also has a good range of shops and attractions including nearby Portmeirion, a narrow-gauge railway, a normal railway and guess what...an excellent hands-on railway museum!

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!

A scenic single track road with views towards Tre'r Ceiri, the historic and perhaps best-preserved Iron Age hill forts in the UK.

The three stones above Nant Gwytheryn (the Welsh language and heritage centre), perhaps representing the three peaks of Yr Eifl. From here a short detour to the centre can be made for a cake in the cafe.

A pleasantly winding descent on double track through the old quarry workings with super views along the Lleyn Peninsula.

Set at the foot of fishing village, Trefor, is a lovely little bay that has clear water and a mountainous backdrop.
