Walk 1 (13.25 miles) starts beside the river Severn and runs alongside delightful mountain streams, before climbing up through pine forest to open moorland with extensive views across the Welsh Hills. A gravel track descends all the way from the watershed, soon finding an infant river Wye, and following it down to the A44, through a landscape dotted with industrial archaeology. The second half of this stage is along quiet forest tracks, through riverside fields, with a final steep climb up to Llwyn-gwyn (just under 400m) before descending to the river Wye and Llangurig village.
