Pentland Hills Access Road

Highlight • Cycleway

Starting at Harlaw Car Park this is an easy way to get up into the Pentlands

Threipmuir to Harlaw Track

Highlight (Segment) • Trail

Pretty steep uphill from Threipmuir to Harlaw. Easy enough to walk up/down.

Tip by

1.93 km

Bit of gravel track hidden away from main paths around reservoirs. Note that the track it connects to (to Harlaw) is steep and rocky, and is tricky to ride on a gravel bike (at least without very low gears and chunky tyres), but can easily be walked up.

The track is narrow and runs very close to the reservoir, so perhaps best avoided after heavy rain.

Threipmuir Reservoir and Harlaw Reservoir

Highlight • Trail

Threipmuir Reservoir (west) & Harlaw Reservoir (east) where built in the mid-1800s to increase the water supply for the Edinburgh area. Both have great lakeside trails for a flatter run in the Pentlands.
