Exit Glacier Guides. This highly regarded outfit conducts tours of Exit Glacier, and not just to the moraine, where most tourists stop: the guides lead travelers right onto the glacier. The company also offers guided hikes on the Harding Icefield and, for experienced climbers, backcountry heli- and fly-ins to remote peaks. To visit Exit Glacier independently you can take hourly shuttle from downtown ($10 round-trip).
