The only Rec site on Horsefly Lake, Prairie is made up of 3 small sites at lake level and more on the bench above the lake. This rec site serves as a good launch for fishing or exploring on Horsefly Lake.
The boat launch is suitable for trailered boats, but turn-around room is limited due to campers near boat launch. Scout it out first.
If you don't have a boat and like to hike, zip down to Suey Bay (opposite side of the lake behind the large island) and from there you can hike 2.7km over to Quesnel Lake via the Suey to Slate Bay Trail.
