Good campsite by the water with plenty space to pitch up. Hot showers, indoor kitchen and drying spot. Pay cash or BACS - quiet when we called in without a booking on a Friday, lovely owners "we always have room for cyclists". a good option to finish day 1 of Traws Eryri.

This picnic spot provides lovely views across Llyn Trawsfynydd and the surrounding mountains. The lake is artificial, created in the 1920s to supply the Maentwrog power station, though it later became the cooling water source for the Trawsfynydd nuclear power station. It's slightly larger than Llyn Tegid (Lake Bala), Wales' largest natural lake.

Moel Ysgyfarnogod is a northern outlier of the main Rhinogydd chain. Its craggy apex is great fun to explore and reveals spectacular views across this often neglected part of North Wales. It's a great one for adventurous kids, as there are loads of little summits and outcrops for practising scrambling moves.
