The Glacier Park Transport Co. is operated in the park under franchise from the Department of the Interior. Daily stage service in each direction is maintained between Glacier Park Hotel and St. Mary Chalets, Many Glacier Hotel and Chalets, Waterton, and Going-to-the-Sun Chalets, Lake McDonald Hotel, and Belton Station. A daily bus trip is made from Glacier Park Hotel to Two Medicine Chalets on Two Medicine Lake, allowing sufficient time at the lake to fish or make the launch trip. Regular motorbus service is maintained between Glacier Park Hotel and Belton. On the west side daily bus service is maintained between Belton, the foot of Lake McDonald, and the Lake McDonald Hotel at the head of Lake McDonald, and between this hotel and Logan Pass on the Continental Divide.

The transportation company and launch companies allow each passenger to carry with him 25 pounds of hand baggage without extra charge, which is usually sufficient for shorter trips. Trunks are forwarded at extra expense. Arrangements can be made for caring for trunks left at entrances during tour of park or rechecking them for passengers who enter at one side and leave by the other. Storage charges on baggage at Glacier Park Station and at Belton are waived while tourists are making park trips.
