The Llyn Peninsula is best reached by travelling along the A 55 dual carriageway through Conwy and then onto Caernarfon (both which have fantastic castles which are worth a visit on the way here). After Caernarfon, take the A499 towards Pwhelli (an ideal place to stop to stock up on food for the week) then onto Llanbedrog. In Llanbedrog take the B4413 towards Aberdaron. Turn right as you enter Pengroeslon and Pant is situated about 1/4 mile off this road.
