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

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.

The bike path to get on at Tumble is closed due to felling trees. They have put a diversion in, but it means going down steps. Apparently it's closed off for about 6 months give or take.
