The classic round is from Hartsop hamlet, up Hartsop Dodd, down and up to Thornthwaite Crag and back down Gray Crag. This extension is worthwhile and interesting, at 8.2miles, 3070′ ascent. Park just past Caudale Bridge on the right going north. Go back over the bridge, through a gate and up the path by the beck, not leaving it ever by too much, past the old mine, where the path keeps to it’s right and zigs back to the ridge. Over Caudale Moor to join the usual route, but at Thornthwaite Beacon keep on round to High Street, down past Knott, and take the first path left down towards Hayeswater. This has recently been “undammed”,although the tidemark persists from it’s time as a reservoir, and the bridge taken down at it’s outflow. There are stepping stones, but a new bridge has been erected where the path is shown crossing the Gill a few hundred yards down. At Hartsop car park, cross the Gill south and turn through a gate right to curve round to the main road, crossing it to a gate opposite and taking the delightful path by Brothers Water, leading to the road to the campsite, and Hotel for a drink. The path to your car is on the opposite side of the road now, beyond the wall.
