The walk leads across moorland and up to this spectacular Bronze Age stone circle (http://www.snowdoniaheritage.info/en/location/389/bryn-cader-faner/), starting from the summit of a minor road at Eisingrug (off A496 between Harlech and Porthmadog).
The route is pretty gentle; nothing steep. It is, however, frequently boggy underfoot. There are also quite a few sheep around.
The road route to the starting point is difficult to find.
If you think you'll have difficulty finding it, let us know beforehand and we'll meet you 5 minutes beforehand, down in the layby at Glan-y-wern, and we can drive up in convoy!
Directions: Leave the Harlech to Porthmadog road at Glan-y-wern (the junction near Tygwyn Station), and take the minor road beside the hump-backed road bridge (Pont-y-Glyn) through Eisingrug.
This soon goes steeply uphill, and after passing the small millpond on the left, you should then take the second right turn, which is into a no-through-road beside grounds of Hotel Maes-y-Neuadd. (see photo below)
Follow this steep (occasionally gated) lane uphill for one mile, across a couple of cattle-grids, and park at the summit, just before it enters a farm at Moel-y-Geifr. (It's steep and winding, and takes about 5 or 6 minutes drive to the summit.)
There is roadside parking (see photo above) opposite the gated track up to the fishing lakes (see photo below).
The walking route goes up this track towards the lakes, heading north-east along a shallow moorland valley.
This area abounds with ancient remains, of which Bryn Cader Faner is easily the most spectacular.
