Blelham is an attractive, reed fringed fishery holding mainly pike, perch and roach. The perch and roach can run to a good size but most anglers visit the tarn in search of pike. While these are not numerous, specimens in excess of twenty pounds are present and caught during most years. The fishing on this National Trust water is controlled by WADAA and is reserved for club members with no day permits available. Because of the surrounding reeds and bog access is very limited with only two swims available - one on the southern shore adjacent to the boathouse and one on a rocky outcrop on the eastern shore. Vehicles can be parked just south of the driveway to Wray Castle from where a public footpath on the right leads down to the tarn. To access the outcrop swim requires a longer walk from the public footpath past the entrance to Low Wray campsite. Overnight fishing is not permitted.
