Boiling River
North Entrance, Yellowstone National Park
0.5 miles S of North Entrance, Yellowstone National ParkThe Boiling River is created where a large hot spring enters the Gardner River, allowing the hot and cool waters to mix into a temperature comfortable enough to bathe in. The natural hot tub makes a great place to stop and relax while soaking in the warm water and soaking up the natural beauty of Yellowstone.
WARNING: After about half a mile into your hike to The Boiling River, the trail circles a seductive looking stream coming from an outcropping on the riverbank. The clear water may look appealing, but DO NOT dip your toes in yet. You can get immediate and severe burns by entering the runoff channel directly. It simmers at extreme temperatures between 113 to 140 degrees! Instead, follow the trail to the end where the stream pours into the significantly colder waters of the Gardner River, where will you be safe enough to enjoy a nice swim.
