Visited June 2010.
Worth noting that the owner of the land where you park asks for a £2 donation to the Air Ambulance to be left in the postbox on the gate to the metalled track to the lakes.
Some drainage and surfacing work has been done on the direct path, which should make it easier going. However, as we visited in very dry weather, I can’t comment on how bad it would be in the wet. This is a very isolated spot in potentially dangerous terrain, so proper equipment and clothing is a must.
You can follow the metalled track to the lakes then keep going along the higher ground to opposite the site, which reduces both height lost in crossing the valley and the amount of distance taken through bogs. However, the ground is rocky and there are some springs.
