Quick FactsOverview
Overview
Boiling River is a well known thermal runoff area near Yellowstone's North Entrance, just south of Gardiner, Montana. Before the June 2022 flood changed the channel, people used to sit where hot water entering the Gardner River mixed with colder current. The National Park Service now reports that swimming is not possible at Boiling River because of the flood impacts, so treat this as a scenic stop rather than a soak you can count on.
If you visit, plan for a short walk and a look at steaming banks, warm runoff, and fast river water. The value is seeing how close thermal features sit to the river corridor and how quickly conditions can change. Bring layers for wind and spray, and carry water even for a brief visit. In summer, expect busy traffic in the north entrance area.
For a water based break, follow current Yellowstone guidance for permitted swimming areas, and never enter hot springs or thermal pools. Boiling River is still a useful waypoint on a day trip between Gardiner and Mammoth Hot Springs when you want a quick stop with a clear view of geothermal activity.
Location & Access
Location & Access
The Boiling River area is along the North Entrance Road corridor between Gardiner, Montana and Mammoth Hot Springs in Yellowstone National Park. The usual access point is the Boiling River Trailhead pullout on the east side of the road, near the bridge over the Gardner River. From the parking area, follow the compacted soil trail downstream and along the river. The first portion of the trail is relatively smooth, but it becomes rougher with rocks, eroded spots, and short grades.
Because conditions changed after the 2022 flood, do not assume the route, parking, or river edge will match older photos or trip reports. Check current park alerts before you drive in, and be ready to turn back if you see closures or damage. Download directions in advance because service can be limited. In winter, the road can be snowy and the wind in the river corridor can be sharp, so bring traction and warm layers.
Use the map link in this listing for navigation, but follow posted signs once in the park. If you are staying in Gardiner, the drive is short. If you are coming from within Yellowstone, allow extra time for wildlife traffic and occasional delays at the gate. Plan your stops around where park services are available, since options are limited outside the main developed areas.
Suitability & Accessibility
Suitability & Accessibility
This site is best for travelers who want to see an iconic Yellowstone hot water runoff area and understand the landscape, not for people who need a guaranteed soak. Since the National Park Service reports that swimming is not possible at Boiling River right now, treat your visit as a short walk to view steam, river flow, and changed riverbanks. If you want an actual soaking experience, look outside the park or choose developed pools where soaking is allowed.
The walk from the pullout is short, but the ground can be uneven and may include loose rocks and narrow spots near the river edge. The park notes that the first segment of the trail is accessible, but beyond that there are rough sections and drop offs. For that reason, wheelchair access is not reliable for reaching the former soaking area. If you have limited mobility, you may still be able to enjoy views from the start of the trail and from roadside pullouts.
Families can visit for a quick nature stop, but keep children close because the river is cold, fast, and unpredictable, and thermal runoff can be dangerously hot. Wear sturdy shoes, carry layers, and plan for sun exposure in summer. Bring water and a snack for the short walk, and keep expectations flexible so the visit still feels worthwhile even if areas are signed as closed.
Safety & Etiquette
Safety & Etiquette
Yellowstone thermal areas can injure or kill. Never enter or touch hot spring water, and do not step onto thin ground near steaming runoff. Scalding water can be present in shallow channels that look harmless. Stay on the established trail, keep back from undercut banks, and avoid scrambling on wet rocks. The Gardner River is cold and swift even in warm weather, so do not wade or swim, and keep pets and children well away from the edge.
Because Boiling River has been altered by flooding, hazards can shift from season to season. Watch for eroded trail edges, unstable boulders, and sudden drop offs. If you see posted closures, respect them. Conditions are not improved by ignoring signs, and rescue in this corridor can be difficult. In winter, ice can form on shaded sections and wind chill can be intense, so use traction and limit time on slick surfaces.
Wildlife is common in the north entrance area. Give animals space, keep food secured, and never approach for photos. If you are hiking, travel with awareness and follow park guidance on bear safety. Use quiet voices around other visitors, and keep the area clean by packing out all trash. Avoid soaps or rinsing in the river. Even if you are only viewing the site, treat it like a sensitive thermal environment and leave rocks, plants, and any artifacts in place.
Finally, manage expectations. The park has stated that swimming is not possible at Boiling River due to the 2022 flood impacts. If your goal is a soak, switch plans rather than trying to force access. A safe visit here is a short, respectful look at a dynamic geothermal river corridor.
