A waymarked circular walk of 2.7 miles (4.4 km) from the forest car park up to Llyn Llywelyn and back down through the trees. Allow around 2.5 hours, with roughly 443 ft (135 m) of climbing. Graded moderate.

From the car park the route works its way gradually uphill on forest roads, opening out to views across the forest to Yr Wyddfa/Snowdon before reaching the secluded reservoir. The lake is the payoff: quiet, tucked into the plantation, and worth a proper stop. The return leg loops back down through the forest to the start. Picnic tables sit along the way if you want to make a slow morning of it.

Footing and the rough bitsNearly all of the loop follows wide forest road, with three short linking sections of track…

Nearly all of the loop follows wide forest road, with three short linking sections of track about 1.5 m wide. One of those short tracks, on the gradual climb to the lake, can get muddy. On the descent back to the car park there is a 40 m stretch of rough, uneven cobbles that needs care underfoot. Sturdy shoes are the sensible choice.

Railway crossingsThe route crosses the railway twice, and both crossings use manual gates.

The managing agency describes this route as suitable for people using adaptive equipment. That is not the same as fully wheelchair accessible: expect the narrow track sections, the muddy patch and the cobbled stretch, and judge against your own kit and confidence.
