Llyn Gwynant is used, like many lakes in north Wales, as a watersports facility by Local Education Authorities (LEA). Access to the water is provided from the roadside car park. At the eastern end of the valley is a crag called Clogwyn y Wenallt which has some steep climbing routes, one of which is 'Lockwoods Chimney', named after Arthur Lockwood who became the proprietor of Pen-y-Gwryd hotel (one mile further up the valley) in 1921. There is a lake side campsite at the north east end of Llyn Gwynant. The National Trust also has a campsite at Hafod y Llan.
