Spruce Hill Lake is large, and has a maximum depth of 12 metres. Other lakes in the park include Witherod Lake () and Narrow Lake (). Park usage The park is used by a number of overlapping groups, including: Mountain bikers, who developed a trail system between 1994 and 1999. However, the number of bikers has declined significantly since about 2001, when trail systems began to be created elsewhere in the area. Hikers: folks simply out for a walk in the woods. Most hikers again use this same small northern portion of the park, but some make use of the older network of old roads and trails in the much larger portion south of Long Lake. Dog walkers.

There is very limited trail access to the lake outside of this area, but for those adventurous enough two small sandy beaches offer secluded swimming on the south side. At the other end of the park, there is swimming spot on the earthen dam at the north end of Pine Hill Lake, where Harrietsfield children swim. Cross-country skiers: most of these use the trails and old roads just north of Long Lake, though the old road linking Spryfield and Goodwood is also suitable. Geocaching: an active and long-established geocaching tradition exists in the Halifax region, and the area within the park is particularly popular, perhaps due to the varied terrain within park boundaries, fishers: the lake is not stocked, but it is reported that there is
