Nice gravel track down to the reservoir with lovely views. Track down can get muddy but good fun. Do-able on a gravel bike

Easy walking along the Eastern and Southern edges of the reservoir, courtesy of the Gower Way (a 35-mile path linking Penller Castell to Rhossili if you fancy stretching your legs a little further). Fantastic views.
