Spencer Iceberg and Placer River Float


Our Hallmark & Most Popular Trip!

Get up close to picturesque icebergs at Spencer Glacier lake after your scenic train ride on the AK Railroad’s Glacier Discovery Train on the Spencer Iceberg Float! Chugach Adventures’ was the original guide service at Spencer Glacier pioneering the area since 2001. Enjoy panoramic mountain & glacial views on a 7-mile scenic river float down the pristine Placer River. This trip is one of the most scenic glacier river trips in Alaska.

We do have a large number of guests join us on the Spencer Iceberg Float trip during our peak season.  If you want a more private rafting or kayaking trip we recommend joining us on a morning trip such as our Glacier Blue Kayak/Raft & Grandview Tour.

I love that I get to ride the train to a remote location, tour around dazzling icebergs, float the river from it’s glacier source…directly to a personal train pick up on the river bank in the wilderness.  We have this amazing access to Alaska’s backcountry and I love being able to share this precious location to guests from around the world.  Erin Henszey – Chugach Adventures’ Trip Leader from Fairbanks, Alaska.
