Visiting Glacier National Park in the Spring
“Spring is a beautiful and quiet time to be in Glacier National Park, however park visitors must be more self sufficient for there are very few services open in the park in the early spring.
Although some services adjacent and inside the park are open year round, most of the concession services and services adjacent to the park reopen for the season in late May to early June. During shoulder seasons, lodging and other guest services are available in gateway communities. Contact respective Chambers of Commerce for listings. If you are looking for accommodations such as hotels, please visit the Travel Montana website to find accommodations outside Glacier National Park. Restaurants and stores can be difficult to find depending on your location, so come prepared.
Camping is available year round at Apgar and St. Mary Campgrounds. Apgar Campground is on the west side of the park, located in the Apgar Picnic Area. St. Mary Campground is located just inside the Park Boundary in St. Mary. There is no running water and flush toilets at either of these campgrounds in late fall, winter and early spring. By early-May, water is turned on at the Apgar Campground and its status changes to full service. By July 1, all of our auto campgrounds are open for the summer season. For more information on our auto campgrounds, please visit our camping page.
Spring backcountry camping can be challenging with many of the campgrounds and trails still under snow. A backcountry camping permit is required and can be obtained from the Apgar Backcountry Office. Trip planning information is available on our Backcountry page or by calling 406-888-7800.
For operating dates and hours of our visitor centers, backcountry offices and ranger stations, please visit our Operating Hours and Seasons page.”
