The north coast of the Lleyn Peninsula provides the opportunity for a long but, in the right conditions, a technically straightforward trip – the distance between Porth Towyn and Trefor is significant (19km) but can be done in a single phase of the tide. The tidal streams run fairly parallel with the coast, consequently navigation is never difficult. A shorter (16km) version can be done from Porth Dinllaen to Trefor - this takes in the most interesting part of the trip; it is also more sheltered from south westerly winds.
Porth Dinllaen is a lovely spot and one which is blessed with the ultimate paddler’s pub, namely the Ty Coch. This delightful beachside inn is tucked in the top corner of the cove. The high tide mark comes right up to the terraces in front of the pub, giving it really unique feel. Unless there are strong winds it is normal to keep out to sea for the section from Porth Dinllaen to Penrhyn Glas. The final section from Penrhyn Glas to Trefor is the highlight of the trip – here the landscape rears up and all sorts of interesting features are seen. The huge guano splattered sea cliff of Craig y Llam drops off the end of Penrhyn Glas, while further north there is old granite quarry workings at Nant Gwrtheyrn (now firmly established as a Welsh language centre). The Trwyn y Gorlech headland, just north again, is also impressive. And lastly, before Trefor is reached, some interesting caves can be found at the Trwyn y Tal cliffs.
There is a car park adjacent to Porth Towyn, there are also car parks in Porth Dinllaen. In Trefor there is a car park by the pier.
