Glanmarlais Camping is situated in the upper Towy Valley, not far from the western edge of the Brecon Beacons National Park. There’s plenty of walking, road cycling and wild swimming to enjoy in the area. Head into the park, for a great circular walk between the two glacial lakes of Llyn y Fan Fach and Llyn y Fan Fawr; perhaps even taking a chilly dip too. The Usk Reservoir is another nice place within the park for a walk, about 17 miles from site. It’s a similar distance to the Llyn Brianne Dam and Reservoir where there are more waterside walks. If it’s a swim you want, though, perhaps head to Junction Pool or Wolf’s Leap Wash Pool, both near Llanwrtyd Wells, and about a half-hour drive from the campsite; if a dip in the Marlais River on site is not enough. There’s mountain biking at Cwm Rhaedr, 12 miles from the campsite, and Brechfa Forest is five miles further. Dolaucothi Gold Mine, Carreg Cennen Castle, the Red Kite Feeding Station, the National Botanic Gardens of Wales and the wooded National Trust estate at Dinefwr, are all within 20 miles.
