The World’s First National Park
LifeFlight on the pad behind Lake Clinic
There are three medical clinics located within Yellowstone National Park, each operated by the park’s primary medical contractor, Medcor.
The clinics are open to the general public, NPS employees, and concessionaire staff. Each clinic provides basic medical care, including stabilization of major trauma or other life-threatening injuries prior to being diverted to advanced care facilities in eastern Idaho, Bozeman, or Jackson Hole. They also provide x-ray, laboratory, and pharmacy services.
For all in-park emergencies, dial 9-1-1.
All EMS functions are provided by park rangers and/or NPS staff via ambulances housed around the park. The Park typically has between 300 and 400 EMS calls (involving transport) during a typical year.
Note that the dates and operating times for the clinics below are in general terms. For specific opening/closing dates each season, see the Visitor Services page. All three clinics have wheel chairs for rent for those who need assistance getting around.
The Mammoth Clinic (built in 1964) is open year-round, from 8:30 AM until 5PM, Monday through Thursday, and 8:30AM until 1PM on Fridays. (it is closed on Thanksgiving and Christmas, however).
