Scenic cruises of Swiftcurrent and Josephine Lakes leave the hotel boat dock several times daily. Grinnell Glacier [1], only partially visible from the hotel, comes into view as the boat crosses Josephine Lake. The one-hour tour is $18 for adults and $9 for children. It’s easy to hop off the boat for a hike or a picnic at Josephine Lake and then catch another boat back to the hotel [2].
