After the peaks it's all flat terrain and definitely more busy on a dry day. Walk the way back after the last peak if you prefer the challenge of it.

Harlaw Reservoir is a popular spot for outdoor activities including walking, fishing, and wildlife watching. One of the highlights is a small embankment on the far side of the reservoir which offers stunning views of Threipmuir Reservoir. On weekends visitors you can get your hands on some homemade crepes from a local van parked near the Harlaw House Visitor Centre.

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

Pretty rough on a gravel bike. Just about ridable in wet weather (with plenty of hike-a-bike) with mud-capable tyres.

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.
