Situated along the Portneuf River in Lava Hot Springs, Idaho, Mary's Campground sits close enough to downtown that a suspension bridge connects the property directly to town, making it straightforward to reach the hot springs on foot. The campground runs from mid-May through early September, with nightly rates ranging from $40 to $85. RVs up to 110 feet can access full hookups, including electric, water, and sewer, and the property also has WiFi, showers, and a dump station.
Sites are heavily shaded, largely by cottonwood trees, though that shade comes with a seasonal trade-off: in late spring and early summer, cottonwood fluff drifts across the grounds in noticeable quantities. The sites are compact and close together, which several reviewers flagged as a consistent drawback. Tent sites in particular run narrow, and there is little buffer between neighbors. The campground draws a lively crowd during peak summer weekends, and at least one reviewer noted that noise from other campers can carry well into the night.
Chris Y. has returned annually and notes there is "a paved trail around all of the camp sites for bikes and skateboards," which adds a practical recreational element for families. The camp host actively enforces site rules, and bathrooms and showers draw consistently positive marks for cleanliness. Not all sites include a fire pit; renters can arrange one separately. Nearby alternatives include Lava Hot Springs East KOA and Lava Hot Springs Spa Motel & RV Park for those comparing places to camp around Lava Hot Springs. Campers who want river proximity and walkable town access without driving will find Mary's worth a look.
