Heads of the Valleys Cycle Network – Sustrans Route 46

The Heads of the Valleys Cycle Network forms the backbone of Sustrans Route 46, a scenic and historically rich cycling route that connects Glynneath in South Wales to Bromsgrove in Worcestershire. At its heart lies the Heads of the Valleys section, a spectacular stretch between Brynmawr and Merthyr Tydfil, offering panoramic views, industrial heritage, and access to the natural beauty of the Brecon Beacons.
