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.

If you're into birding, keep an eye out for Peregrine, Kestrel, Raven, Wheatear, Meadow Pipit, Skylark, Whinchat, Red Kite and Curlew - which have all been spotted here.
