Ash Campground is one of several campgrounds within Balsam Lake Provincial Park, situated on the west shore of Balsam Lake in Ontario's Kawartha Lakes region, part of the Trent-Severn Waterway.

The campground offers 50 electric sites and no non-electric sites, making it well suited for RVs and campers requiring power hookups.

Sites at Ash Campground are largely open and exposed, with little tree cover or privacy between neighbours, though the campground does include a number of convenient pull-through sites.

A canoe and kayak launch is located nearby, and the park's amphitheater is also in the area. Balsam Lake offers fishing for pickerel, pike, muskie, and both largemouth and smallmouth bass.
