The easiest route to Assycombe row ,is to park by the Forestry hut in Fernworthy - then take the track up from the other side of the hut. Through (or round)the gate and carry on up the track over the first "cross road" through the forest over a second "cross road" and carry on past a third "cross roads" until the track forks. Take the right fork and follow the track for just under 1/2 Km and look out for the top of the row on your right. It's a steep walk but should only take 10/15 minutes and is by far the best approach.
To go back walk down the row and follow a small track through the trees io meet a forestry track.Turn right and follow the track for about 1 1/2 Km to join the main Fernworthy road.Take a right here back to the forestry hut.
There is a hut circle near the bottom of thr row and you can access a couple more hut circles at the site by walking through the trees from here into a clearing.
