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.

Anyone who cycles to the Garden can, on handing in their helmets for safe keeping, get into the Garden for half price (based on the adult ticket price). The Carmarthen-Llanelli loop on the National Cycle Network route 47, goes past the entrance of The National Botanic Garden of Wales, known as the Celtic Trail.
