Near Tumble the trail is closed due to a landslide, so be aware you cannot make it all the way through to crosshands.

Free parking opposite the convenience store/pub. Cafe on the foreshore is excellent.

This beautiful reservoir is framed by the stunning mountain scenery of the Brecon Beacons. From the vantage point of the Swidd Valley Trail, you can enjoy a great view of the reservoir and its picturesque surroundings.

Beautiful little ruined abbey at the start of a real nice walk. Like Yugen says, limited parking at the start point. Pick a quiet weekday to visit if you can.

Worth leaving Sustrans Route 4 to take a look at the castle. Only a short diversion
