You'll encounter a mix of hiking paths, footpaths, and shorter stretches of track, street, and road. A significant portion (about 28.3 km) is unpaved, with gravel and natural surfaces. Expect steep climbs, especially from Llanthony Priory, and exposed, potentially windy ridges. Parts of the Offa's Dyke Path are laid with coarse gravel and limestone slabs for a firmer surface.

Carry plenty of water, high-energy snacks, a map and compass (or a reliable GPS device), a first-aid kit, and a fully charged phone. Sun protection is also advisable.
