May 23, 2026, Sunken Road Near the Viaduct

Part of the Cambrian Way, this section is not for the faint hearted, the track is very rocky and full of huge pools. The only way to navigate is to get your feet wet! The river also floods the path, shoes off, and wade with the bike!! I recommend the road which is just the other side of the river.😅
