Also known as Rhoscolyn Beach, Borthwen is a bay of sand backed by low dunes, with some smaller sandy coves on either side. A small P&D car park is situated just behind th beach, and is reached along a lane from the village of Rhoscolyn. This lane is extremely narrow with sharp corners, and only just enough space for cars and pedestrians to pass. If the car park is full, vehicles must return to the village where there are some more (roadside) places to park. On a busy day, it's best to park in the village and walk; a footpath off to the left at the rear of the church makes a more interesting (and traffic-free) route than the lane.Facilities at the beach include (seasonal) toilets ♿, cold water showers and a slipway for launching boats. A Beach Warden is on duty from end of May to early September to collect launch fees etc. Due to its proximity to Valley airfield, there can be frequent noise from aircraft. Dogs are allowed at all times.
