Hikers and water enthusiasts will find Ann Lake Campground serves as a solid base for exploring Sand Dunes State Forest's trail network and lake access. This first-come, first-served campground operates from May through November, with sites scattered along a main loop road that several campers describe as rough and slow-going for RVs.
The campground layout offers variety, from open sites near the entrance suitable for larger groups to more secluded walk-in spots tucked back in the pines. Johnny H. notes "the further back you go on the road, the more spread out sites get." Most sites include fire rings and picnic tables, though some reviewers report maintenance issues like broken grills or glass debris that require cleanup upon arrival.
Water access requires either a short drive or 15-30 minute hike to reach the swimming beach on Ann Lake. The forest's trail system provides hiking and biking opportunities, with campers frequently spotting deer along the paths. Cell service varies significantly by elevation, with higher sites receiving better coverage while lower areas may have no signal at all. Several water spigots and vault toilets serve the campground, though there are no hookups or showers.
Weekend arrivals should plan for early check-in, as popular sites fill quickly during peak season. The nearest supplies including firewood and ice are available at Sand Dunes Stop gas station, about 10 minutes away by car. Campers exploring the broader region can find campgrounds around Zimmerman for additional options. A state forest pass is required along with the overnight fee.
