This is a great bike section with a nice approach over the bridge and causeway of Threipmuir Reservoir that has great views over each side. Exponential Hill itself is a beautiful tree-lined avenue that is very scenic. The section itself is only 462 metres long but has a sharp 49 metres of height gain. A stunning place overall and a nice hill section to take in on the way to Bavelaw Castle.

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.

Harlaw Reservoir was constructed between 1843 and 1848, at the same time as the larger Threipmuir Reservoir upstream. It's a simple gravity earth dam construction that adds to the volume of water available for Edinburgh.

North Esk Reservoir is an easy 5k walk from Carlops village. You can park your car in the village and choose one of the two main paths or do a circular walk. Easy to intermediate terrain with some steep hilly parts as well. The reservoir is a gem.
