About Us

Chugach Adventures (formerly known as Chugach Adventure Guides and Class V Whitewater) was founded by Mike Overcast and Alpine Skiing Lillehammer, Norway Olympic gold medalist Tommy Moe in 1996, operating trips on Six Mile creek.  The company explored & pioneered the Spencer Glacier area in 2000 and partnered with the AK Railroad starting in 2001 to offer trips via the Glacier Discovery Train to Spencer Glacier.  Long-time Chugach guides and Girdwood locals, Melanee and Ari Stiassny, purchased the rafting business in the fall 2012.

Melanee & Ari Stiassny share a passion for Alaskan adventure with their three kids.  In winter 2015 /16, Chugach Adventures was awarded a ten year permit with the USFS Chugach National Forest to continue operating tours at Spencer Lake and are stoked to be now offering kayaking, overnight camping, heli hiking, and glacier salmon bakes at Spencer Glacier.

We believe strongly in sharing our local stories and firsthand experiences of what we have seen and witnessed as Spencer Glacier has receded thru the years.  We are committed to finding ways to protect our environment and aim to share our knowledge to our guests.

Our operations and our guide team is one of the top notch guide services in Southcentral Alaska.   We were awarded the AGA – Adventure Green Alaska – certification this past winter, largely because of our local hire policy.  We are proud to support local Alaskans and to share our Alaska with visitors from all over the world.




Our Season

Our season starts in mid-May and runs through mid-September. These target dates generally shift from year to year depending on weather and river flow. Occasionally we have to push our start date back, due to the presence of deep snow. Please contact the office at 907-783-1860 to inquire about mid-May bookings.

Spencer Tour runs:  May 25 – Sept. 16, 2019.


The rivers run by Chugach Adventure Guides are generally fed by melt water from deep winter snowpack and from high alpine glaciers. While making for great flow and an excellent river experience, this also makes for extremely cold waters. With this in mind, you will be provided with all necessary equipment to make your trip enjoyable and safe, but an extra pair of wool socks is always advised.
