This is a well worth strenuous walk of over 2 1/2 hours for the magnificent scenery that is encountered. The walk starts on the Sally Gap Road at the entrance to the Guinness' Estate. There is room to park at the other side of the road without blocking the gate. Unfortunately there is a steep decent (190 metres) at the start of the walk which must be encountered as an hard climb on the way back. I do not know on this walk whether we are trodding on the generosity of the estate or on a public right of way, but in either case the estate should be thanked for a well maintained route to Lough Dan, as well as the sight of many of their deer. The return route is the same as the outward journey.

The road to the bottom of the glen is sealed and the rest of the way to Lough Dan is a gravel track. There is one stile to cross and about two gates to go through. Half way down to the bottom of the glen there is a sign indicating 2  miles to Lough Dan. Be warned this distance is in Irish elastic miles.

When I got to the waters edge I realised that although I had often seen Lough Dan through the boundary fencing of private property (for over 50 years) I had never until actually got to the waters edge and put my feet in the water. As it was February I will leave this experience to another day.
