Pen Caenewydd

The walk up Pen Caenewydd rewards you with genuinely impressive views across the Tywi Valley, one of those rare moments where the effort actually matches the payoff. It's a proper hill rather than a gentle stroll - expect steep sections that will have your legs working - but the summit sits at a reasonable height that most walkers can manage without needing technical gear.

This is one for people who actually like walking. If you're after a quick family amble with ice cream at the end, look elsewhere. But if you've got teenagers with decent fitness levels or adults who don't mind a proper hike, the panorama from the top makes it worthwhile. Clear days are essential here - turn up in drizzle and you'll see precisely nothing.

Llandovery sits just down the road and makes a logical base, with the climb accessible from multiple directions depending on your mood and experience. The nearby caravan parks - Erwlon and Riverside Pods are closest at 3.5 miles - position you well for tackling this and exploring the broader Brecon Beacons landscape.

Go early to beat crowds and secure decent parking. Allow two to three hours for a steady round trip. It's free, obviously - you're climbing a Welsh hill, not entering a theme park. The real cost is the petrol to get to Carmarthenshire.
