MT Sobek has been a pioneer in Alaska adventure travel since 1972, always placing a strong emphasis on responsible travel practices that support local communities and protect the natural environment.

Praised by National Geographic Adventure, this spectacular 13-day rafting expedition features wilderness paddling, riverside camping, tasty meals, and tales told by seasoned guides around a crackling campfire.

Our Alsek trip is led by the most capable and knowledgeable guides on the river. Our crew has over 100 combined years of experience on Alaska rivers.

Spectacular Class II-IV rafting along the mighty Alsek River, extraordinary wildlife spotting, and riverside camping.

After the first evening in a Jeffersonian style hotel, MT Sobek riverside camps, with meals served around the campfire beneath the stars.

Enjoy long Alaska days, with potential rain & chilly winds near glaciers. Daytime 55°-65°F. Evenings 40°-55°F.

We are making a border crossing into Canada, so you will need a passport as proof of nationality. Please check visa requirements for entering Canada if you are not a U.S. or Canadian citizen.

MT Sobek provides synthetic sleeping bags, sleeping pads and expedition tents at no extra cost. We also provide rain gear, dry suits, and boots.

The Alsek River is deep in the heart of the largest wilderness area in the world, and there are less than 200 people who raft this river annually. This is more of an expedition trip due to its remote wilderness.

Not necessarily. We can make adjustments to our itinerary if the weather is not cooperating. This means sleeping in, delaying departure from camp, or other adjustments. We carry a large group tarp with us that allows for rain shelter and our tents are expedition quality.

Prior rafting experience is not essential. However, this trip is an expedition with wilderness camping, so being an active participant willing to be caught in variable weather with a positive attitude is a must.

On each night of your Alsek adventure you will enjoy camping in spectacular spots right next to the river, often with views of glaciers. Included in our expedition-style trip are three-person four-season tents for every two people, plus Thermarest pads and fresh sleeping bags. At lunch and dinner time you will enjoy gourmet meals carefully prepared by the guides.

Your riverside camping experience includes nightly camps on the banks of Alsek River. Included in our expedition-style trip are four-season three-person tents for every two-people and includes a Thermarest pad and fresh sleeping bags. All camping spots are in spectacular locations right next to the river, with often views of glaciers. At lunch and dinner time you'll enjoy gourmet meals.
