Ride 160 miles down the Alsek River, through the largest contiguous protected wilderness in the world. Raft Class II-Class IV rapids watching glaciers calve into the water and spotting spectacular wildlife. Camp riverside and enjoy delicious meals while listening to river lore around the campfire. Take a helicopter portage over a risky stretch of river, and float past dense canyon forests. With raw nature on display at every bend, this is a unique pilgrimage for thrill-seekers, through one of the earth's last great frontiers.


Arrive in Haines, Alaska

Arrive in Haines, Alaska by 3:30pm to have enough time to check in and clean up for the 5pm pre-trip meeting and welcome dinner at the Halsingland Hotel.

Travel to Haines Junction in Yukon Territory, Canada

After breakfast, board a van for a beautiful drive up the Chilkat River Valley, and on to Haines Junction in Yukon Territory, Canada. En route stop at the Kluane National Park visitor center to learn about this vast wilderness. After lunch, drive to the put-in point on the Dezadeash River. (You may choose to hike part of the way.) Begin floating down the Dezadeash to the confluence with the Kaskawulsh River, where the Alsek River begins. (If it's very windy, the river trip may begin the next morning.)

Raft the Mighty Alsek

Continue downstream on the Alsek, passing through mostly Class II rapids and spectacular scenery of large bedrock islands. There may be time to hike into the heights above the river for panoramic views. Float further into the wilderness and camp near the Lowell Glacier, part of the vast St. Elias icefields. The river flows into Lake Lowell, formed by the terminal moraine of the glacier; camp on that moraine for a striking view of the glacier.

Raft Across Lowell Lake & The Lowell Glacier

If the winds are calm, we make our way across Lowell Lake to where the Lowell Glacier ends. The lake is teeming with icebergs that have calved and fallen off the glacier on the other end of the lake. It's a spectacular sight to raft through these glacier chunks, and listen and watch the glacier's movement through the night.

Navigate the Icebergs of the Lowell Glacier

Launch the rafts into the river and navigate through the icebergs at the snout of the Lowell Glacier. Take in this surreal scene as the icebergs calve off the glacier and float in this lake-like section of the river. The river picks up speed dramatically as it begins to cut through narrower canyons and increase in volume.

Run the Rapids of the Challenging “Lava North”

Take easy routes through some of the rapids; by mid-afternoon, though, encounter "Lava North," a challenging section of Class IV whitewater that's fun and thrilling. Our guides will scout the rapid beforehand and determine the best route through.

Discover the Luminous Turn Back Canyon

For the next few days the water is swift with continuous small rapids as the river cuts through the Alsek Range. Watch the scenery and look out for wildlife such as grizzly bear, moose, wolf, muskrat, wolverine, mink, snowshoe rabbit, hoary marmot, and Alaska red fox, along with numerous bird species. Reach the Tweedsmuir Glacier with its Turn Back Canyon, filled with sharp drops and horrendous currents.

Helicopter Ride Over Turn Back Canyon

Prepare the gear for transport, and board a helicopter for a short flight to the gravel flats south of the canyon. From the chopper see every hairpin turn and the churning water crashing into the canyon walls. The scenery changes on the other side - the river is wider, there are numerous braided channels and more vegetation, and bald eagles perch along the mossy cliffs of the Icefield and Noisy Ranges. Relaunch the rafts and drift through the wide valley towards the majestic confluence of the Tatshenshini and Alsek rivers.

Continue Down the Tatshenshini River

Continue down the river through deep forested canyons toward the coast. On the southern horizon, a dozen glaciers flow down from the Fairweather Range, while the Alsek disappears back to the north and east into the symmetrical peaks and waterfalls of the Noisy Range. To the west, the main channel of the Alsek flows into the Fairweather Range, where it seems to sink into the forest. The river below its confluence with the Tatshenshini is a vast, gravel flat, braided with channels and ringed with willow, birch, and alder forests.

Pass the Walker Glacier

Closer to the Gulf of Alaska, the climate becomes more maritime and the glaciers more numerous. Farther down the river, pass the Walker Glacier, which has sprawled down its valley and is visible from the river. Its blue and white shape dominates the view for quite some time.

Float Towards Alsek Lake

Continue to float towards Alsek Lake, spotting many species of birds, including bald eagles, semi-palmated plovers, spotted sandpipers, northern phalaropes, American pipits, and more.

Paddle Among Sculpted Ice Flows of Alsek Lake

Watch and listen as giant chunks of ice calve into the water from the 7-mile face of the Alsek glacier. Some icebergs are 75-feet high, indicating a depth below the surface at least twice as great. The guides will row among ice floes sculpted into bizarre, fluted, ever-changing phantasmagoric shapes — a veritable "iceberg garden."

Depart from Dry Bay by Bush Plane

After floating into the flat, forested plains beyond Alsek Bay, arrive at the Dry Bay Fishing Company outpost along the estuary of the Alsek River. Board a small aircraft for a spectacular charter flight to Yakutat in time for the scheduled Alaskan Airlines service to Juneau (the trip is tailored around this flight, and Juneau is your gateway city to other destinations).
