GPS Cycle and Walking Routes

Flotterstone Glencorse Reservoir Walk

2 miles (4 km)

This circular walk explores the area around the Flotterstone visitor centre in the Pentland Hills. The 2.5 mile route starts from the car park and follows a waymarked trail towards the pretty Glencorse Reservoir. It's a fairly easy walk with a small climb which provides nice views back down to the water.
Starting from the car park you follow the trails west along Glencorse Burn before a short woodland section leads you to the reservoir. You can then follow a path along the water before climbing toward Castlelaw Hill. From here it is a short descent back to the car park and the finish point of the walk.
On the way look out for the Blue plaque dedicated to Nobel prize winner CTR Wilson. The local man won the prize for physics in 1927, after devising a cloud chamber apparatus to reproduce clouds, which proved invaluable in detecting ionising radiation.
To continue your walking in the area, head west to visit Harlaw Reservoir. The site has a nice 2 mile footpath running around the perimeter with views to the adjacent Threipmuir Reservoir. Another good option is to head towards Livingston and visit Eliburn Reservoir and Cobbinshaw Reservoir where there's more lovely views and lots of wildfowl to look out for on the water.
To the south you will find Gladhouse Reservoir, Edgelaw Reservoir and Portmore Loch which are also very peaceful and beautiful.
