Misty start to the day and wanted a shorter walk , so did the pleasant valley start to Walk 20, past Wharton Hall and Pendragon Castle, the latter currently blocked to entrance. Ascended the High Seat ridge with clearing visibility and sun, as for the Walk, but at the first zig-zag on the grassy track kept straight on to climb High Brae, and then it was an easy walk to High Pike Hill. Reversed this part of Walk 21 down to the road by the sign and north up the track, forking left at the first junction onto a track not on the map. When this crests the ridge under Tailbridge Hill a turn left up the dry tussocky pathless slope past some odd low walls leads upto the large summit cairn. From here a few yards right, north, an easy descent to the wall allows a quad track to take you down to the road a short mile from Nateby and so join the end of Walk 21. Four hours, nine miles when done from Nateby.
This Tailbridge Hill descent shortens the Nine Standards Walk if weather/time alters your plans.
