This park offers a popular 23 site campground and day-use area which has a developed beach, a horseshoe pit and a nature trail. Some activities offered include hiking, exploring and fishing.
The large, deep lake is usually fished on a troll. Fishing for rainbow trout is a favourite pastime of many visitors. There are a number of smaller lakes excellent for fly-fishing. Two unnamed lakes are in the park, and were once the site of a hatchery operated to restore the run of sockeye to the Horsefly River.
Fir, spruce, birch and cedar clothe the slopes along the lower reaches of Dillabough Creek at the west end of Horsefly Lake. There are old growth cedars and Douglas firs throughout the park.
