Kidston Lake is a lake in the Spryfield area of Halifax Regional Municipality, Nova Scotia, Canada. An area along its eastern shore has been made into a municipal park, with artificial sand beaches and a lifeguard in the summer months. It is a popular swimming destination and offers a good swim from the beach to two rock formations called Breadloaf and the Whale's Back. There are trails all around the lake, and going to Leblin Park and other places such as the Greystone and Green Acres subdivisions. The granite barrens south of the lake are an excellent place to find blueberries, which foxes and porcupines share with the more adventurous of the local children. The most famous portion of the park is the Rocking Stone, a 90+ ton glacial erratic boulder which can still be rocked with a lever, but which used to move quite easily, before a band of sailors from the nearby Halifax garrison rocked it into a more stable configuration in the 1890s, and before its base was worn down by excessive rocking in the 1980s and 90s when the park was first developed. A lesser known but equally interesting large glacially-deposited granite monolith called Table Rock, can be found NW of the narrow passage at the northern end of the lake, where it empties into a boggy area: it is a flat, approximately 30 ton rock firmly balanced upon three rocks, the smallest of which is about the size of a volleyball.
