Seymour's Swallet - January 2013

Seymour's Swallet has now been reopened but following the separation of ownership of the farm buildings and the land the access route has changed and in particular visitors must not call at Hoarthorn’s Farm to ask permission.

The access route is now: 

At Edge End on the A4136 Gloucester-Monmouth road, turn into Hoarthorn Road (opposite the Coleford turning) and head down the hill taking the right-hand fork, continuing down the hill.  Continue past the farm buildings (Hoarthorn’s Barn).  Where the tarmac ends follow the track (gates) to the left and continue past the cattle sheds on your right.  Follow the track through gates where it turns to the right following the Hoarthorns valley down.  Continue through next gate to a junction with another track coming from the right.  Park here on the area of hard standing being careful not to block any farm access.  There is no parking beyond this point. Continue along the main track following the Hoarthorn valley for approximately 150m, the swallet is within the obvious concrete ring on your right (although obscured from view when on the track).  Caution:  Although the farm track is fairly well graded it can get muddy during periods of wet weather.
