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

Redford Bridge crosses between Bravelaw Marsh to the west and Threipmuir Reservoir to the east. It's a useful access point to the Pentland Hills from the north.

Very testing at night with a gravel bike... may be directly responsible for finishing off a set of disc brake pads!

Steep, tree-lined drive up to Bavelaw castle. Reliably car-free. Especially beautiful at dawn.

Rough track that heading East to West feels like you are miles from anywhere. Occasional deep sand can be an issue, as can tennis ball-sized rocks on some sections.

Slightly easier going east to west. Seems to be getting more eroded each year.
