Organized Tours & Activities--Narrated boat tours from Lake McDonald, St. Mary, Two Medicine, and Many Glacier are offered daily from mid-June to mid-September by Glacier Park Boat Co. These "scenicruises" combine an hour-long lake cruise with a short hike or picnic. Spectacular views of Lake McDonald, the Grinnell Glacier, and the panoramic rugged cliffs ringing St. Mary Lake are just a few of the photo opportunities you may have. The boats typically depart every other hour, five times each day, although schedules are subject to change in late season or if the weather is inclement.
