Snowdon (Welsh: Yr Wyddfa), 1085 meters high, is beautiful to see. Here you have a good view of it in clear weather.

Llyn Llywelyn is a small shallow mountain lake surrounded by open moorland and forests. It is a natural spot to pause, picnic and soak up the serene atmosphere before continuing your walk.

You start a hike in this forest by walking under a kind of gate. A nice start.

Spacious car park, called Rhyd Ddu Station Car Park, with some facilities such as toilets and the possibility to refill drinking water. Parking is paid (up to 4 hours: £5, all day £8). Next to the car park is a stop for the Welsh Highland Railway.

This lake is located near the village of Rhyd-ddu (not at the foot of Cadair Idris mountain). The lake has a surface area of 50 hectares and is situated 182 meters above sea level. According to John Leland in the 16th century, the original name was "Llyn Cadair yr Aur Frychin". The lake became famous through the sonnet Tyr Ysgol (The school building) by the poet TH Parry-Williams. (Wikipedia)
