Rafting activities in Alaska
Offers guided raft trips through some of the whitest water in Alaska, the class V canyons of Sixmile River (around US$130). If you can't handle that icy roller coaster, trips through class III rapids (around US$75 to $95) are available.
On a grand scale of adventure is the exciting 9- to 10-day raft trip down the Tatshenshini/Alsek River system, from Yukon Territory to the coast of Glacier Bay. This river trip is unmatched for its scenic mix of rugged mountain ranges and dozens of glaciers. You can book through Alaska Discovery which runs this trip.
