It’s fine. Varied landscapes, a lot paved, which is not great for a hikers knees. If biking, you’ll need something more robust than a road bike.

Helpful signs throughout trail. Did it on mountain bike but the trail is a gravely path the majority of the way round. The uphill section is a little bit of a slog but absolutely no technical difficulty on any of the section. The road section has a cycle/walk path all the way along.

Great trail, with varied scenery and a great bridge across the reservoir. A gentle gradient throughout and a few places to stop for snacks if you’re not a well-prepared walker. Really enjoyed it and I’ll be taking family back with me next time.

An amazing and really enjoyable walk. Massively varied from walking on a wooden bridge across the reservoir to getting up close and personal to a disused nuclear power plant oh and a 300 meter drop over a damn.
