Llyn Llewelyn lake through the trees at Beddgelert forest

This easy circular walk follows forestry tracks through Beddgelert Forest to the quiet shores of Llyn Llywelyn, with wide views towards Yr Wyddfa (Snowdon) and Yr Aran along the way.

You’re in the right place if you’re looking for a relaxed, low-level forest walk with gentle gradients, suitable for most abilities and ideal for a peaceful half day outdoors.

The route begins among the trees of Beddgelert Forest, climbing gradually as it weaves in and out of woodland. As the path gains height, the trees begin to thin, opening up views across the surrounding hills and towards Yr Wyddfa and Yr Aran.

At the heart of the walk lies Llyn Llywelyn, a small, tranquil reservoir surrounded by open moorland and forest edge. It’s a natural place to pause, enjoy a picnic, and take in the quiet atmosphere before beginning the gentle descent back towards the starting point.

The walk makes use of wide forestry tracks throughout, making navigation straightforward in good conditions. While the ascent at the start is noticeable, it is steady rather than steep, and the overall route feels calm and unhurried.

This circular walk is a good choice for families, slower walkers, or anyone wanting an easy outing close to Beddgelert. One important note: the forest tracks can be confusing in places and it’s genuinely easy to take a wrong turn — bring a map or download the route before you set off.

“There’s a picnic table at the top by the lake which is worth knowing about — it’s a lovely spot for lunch before heading back down. Just don’t attempt this one without a map. The forest paths look similar and it’s easier than you’d think to end up on the wrong track.” — Delyth, Perthi Holiday Cottages

Step-by-Step Walk Guide

Numbered steps with photos to help you follow the route.

The start of the walk and parking is just off the A4085 towards Caernarfon. It’s about two miles outside Beddgelert village on your left-hand side, signposted Beddgelert Forest.
Parking is possible right next to the main road or there is another car park if you follow the gravel road. To start your walk, go through the gates that cross the train track.
Follow the track uphill. Don't take the first right junction signposted Rhyd Ddu. Take the next right.
At the next junction keep right, following the yellow Derwen waymarkers. Keep a lookout for these waymarkers because they will guide you all the way to Llyn Llywelyn.
The path will guide you around Llyn Llywelyn. If you wish to stop for a picnic, cross the dam here to the picnic benches. The footpath continues downwards into the forest.
At the crossroads, take first right downhill.
When you reach the t-junction, do not turn right on the Derwen path but turn left back towards the starting point.
Follow the path downhill until you reach the train track. Cross the tracks and turn left to return to your car.
