1 Although the route directions here may sound a little complex, the route-finding is simple, for here the Offa's Dyke National Trail markers will guide you all the way to the Beacon Ring at the top of the mountain. From the Cock Hotel, take the B4388 north through Forden and turn right along the lane, signposted 'Long Mountain'. This bends left to climb uphill on what is the course of Offa's Dyke. The earthworks here are either side of the road in places and will continue through the woodland that you are about to enter.
2 Turn left when you get to the Offa's Dyke footpath sign to follow the right of two tracks. This passes the Lodge and goes into Green Wood, which is part of the expansive Leighton Estate.
3 The path, still accompanied by the earthworks of Offa's Dyke, stays parallel to the road for a while, but then swings left in Pole Plantation. Beyond this take the signposted right fork that climbs and swings right. You soon leave this for a small path on the left, which descends through the trees, in steps in the later stages, to reach another forestry track. Turn right along this to pass around the tree-filled hollow and a tall brick retaining wall that are the remains of Offa's Pool, part of an elaborate water system that provided power for the estate's farm machinery.
4 Ignore the path descending left but continue along the track that soon swings right to pass another pool. Beyond this a narrow path heads out of the woods to a narrow lane at the far side of the estate.
5 Turn left along the lane then climb right, along a tarmac forest road to a junction of tracks. The one on the right you will use on the return route, but on this occasion go through the left fork track alongside the spruce trees of Phillips's Gorse. Near the top end of the woods go over a stile on the left and continue alongside a hedge to the afforested knoll of Beacon Ring.
6 Retrace your footsteps to the previously-mentioned junction by Phillips's Gorse (the useful-looking bridleway marked on the OS maps doesn't exist on the ground and is impassable). Turn left along the scrub-lined grassy track that leads out to the lane running the length of Long Mountain. Turn right along the lane, which was formerly a Roman road, linking their fort Lavobrinta at Forden with one at Wroxeter. Today this quiet hedge-lined country lane will ease you back to the car.
