Situated just beside Tory Hill is Lough Nagirra , which has its source in the northern portion of the lake in a deep spring. The lake has been described as having immense depth. Wild birds sometimes gather there in large numbers. Otters, swans, heron, wild duck and geese can often be seen at the lake. People from Limerick city and county enjoy fishing there and competitions are held every year.
Some people go fishing and boating on the lake.
Known in ancient times as Dromasail, Tory Hill also has a fascinating history as well as being a site of major archaeological significance. Recent research indicates that Tory Hill may also be of significant geological importance. A research team at U.C.G. has discovered exceptionally thick Late-glacial deposits in a large basin near the base of the hill. With a thickness of 10 metres, they are possibly the thickest in Europe.
