Drive out the back road from Dalavich and go over to Kilmelford and get a permit from the shop/post office at the end of the road. Make sure you get the right one as there are two covering different lochs. You don't want the angling club one.
Drive back up the road and park at the cattle grid, or just beyond if the farmer hasn't got his feed station for the cattle there

You will see a gate on the opposite side of the road with a path to Losgainn Beg. Fish down the loch, whichever side you like. Fish around and in the lily beds with strong tackle
Follow the track up the hill and you will see another loch to your left, Loch a'Mhinn, again choose which direction you want to fish in. If left leave the loch at the corner with the high bank and follow the wall, there is a path, to Loch na Curraigh. Fish down the path side and around the bottom. Don't try and go right as it is floating bog and you might not be found for a few thousand years

If you go right around a'Mhinn when you get to the top end at the outlet burn, cross it and head up over the hill to na Curraigh.
At the end of the loch you can retrace your steps back to the car or head down the glen and, keeping high, traverse left round the hill and down to Loch a'Phearson. Fish left around it until opposite the island at the top and head up the small burn coming down the hill here and follow the indistinct path back to the car.
Two or three miles of walking but worth every step. You can see I like the place
