Surrounded by coniferous woodland and SSSI moorland, the reservoir is known to be a vital area for common toads who hibernate on the moorland. The water body also supports brown trout, grayling, bullhead, eel, stone loach, minnow and lamprey.

The circular path is wide and well surfaced in entirety and only has one gradual small incline and decline in the northeast corner.

There is car parking to the north of the site and Osmotherley village has public toilets and a small shop.
