Walking and outdoors
Caernarfon Castle (Cadw, LL55 2AY) is the dominant UNESCO World Heritage Site and unmissable. The King's Gate lift makes upper gatehouse levels accessible without stairs, though most towers still require spiral steps — check mobility needs before booking. From the castle, the Y Foryd tidal estuary and nature reserve is a 20-minute walk south along the Seiont riverbank and good for birdwatching. The Welsh Highland Railway runs from Caernarfon to Beddgelert and Porthmadog — a spectacular way to travel without driving through Snowdonia.
