Walk - Llyn Trawsfynydd and Tomen y Mur (Roman remains) circular

Circular walk of about 4 miles, firstly along the wooded edge of Llyn Trawsfynydd, then gently ascending along farmland tracks to reach the Roman remains at Tomen-y-Mur.  Return through sheep pastures and a little woodland, to cross the A470 again and return to the power station/cafe entrance.
Site of the Roman Amphitheatre
Start at the cafe near the Trawsfynydd Power Station entrance road. No dogs allowed inside cafe, but there are picnic tables outside, beside the lake. Really nice cafe. Clean toilets.


Free parking at Trawsfynydd Lake Activity Centre, either by the cafe (to the left), or off the Power Station approach (to the right).


Easy level walking beside lake for first half. Gentle sloping track to the ruins.

LIkely to encounter some livestock on the section of the walk around the area of the Roman remains, and in some of the fields on the return.

Several kissing gates and field gates. One post & rail stile. Mostly on firm tracks and footpaths. The descent from Tomen y Mur back to the lake is by a grassy footpath across some sheep pastures.


Trawsfynydd Power Station LL41 4DT is well signposted 1.5 miles north of Trawsfynydd on the A470.
