A few hills that take the BPMs up but the rewards are fantastic vistas

Quite unusual, this church: its tower, its cruciform plan and - that I’ve not seen before - it’s oriented SW-NE. (And why not??) Inside, it’s peaceful calm, welcoming and with a cared-for atmosphere. Go visit if you’re passing.

Little Puncheston has several interesting buildings, including its two chapels and church. There are two listed cottages here to: Ty Newydd and White hart. At the time of writing (March 2025), the Drovers Arms pub is temporarily closed.

A lovely brewery that's worth adding on a few miles for. Check their website for taproom opening hours as they will change throughout the year
