Very nice bridge not for traffic though as it’s a single lane track with passing gaps for pedestrians.

Climbing Gospel Pass northwards from Capel-y-ffin takes you over Wales' highest paved road at 549m through stunningly remote Black Mountains scenery. Prepare for steep initial ramps hitting 15% or more shortly after leaving the hamlet, before the gradient eases into a long, steady drag across the high moorland plateau. Be prepared for a rough, potentially potholed single-track road surface requiring caution. The wild beauty and panoramic views are immense, but check conditions and access to Capel-y-ffin beforehand.

Super popular bike stop in the centre of Hay On Wye. It has ample seating, inside and out, along with a good selection of tasty food and cakes. A great rest stop.

This is a cracking bike stop, not far from the beautiful river bridge in the lower part of the village. There is seating at the rear of the cafe and some more at the front. You can keep your eye on your bikes at either location. Super coffee, and super sticky cakes too. There is also a shop there if you’re a multi day tourer.
