Spencer Glacier 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 Glacier 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 Glacier 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.

Weather – Trip Adjustments:

Water levels, wind, and other natural factors beyond our control may cause us to alter your trip for your safety & enjoyment. 

For example on windy days, if you have booked a Kayak trip, we reserve the right to have you join us on a rafting trip. With our Spencer Glacier Float trip, the river portion is based on water levels in the river. We reserve the right to modify your rafting trip to a Spencer Glacier Float lake tour going closer to the glacier if the water levels are not sufficient for a safe/enjoyable trip down the Placer River.  

Landing zone locations and the extent of our glacier hiking & moraine treks are dictated mostly by the weather of the day and the group’s activity level & speed.

Chugach Adventures does not cancel trips due to inclement weather, nor provide refunds when adventures are adjusted based on weather.

Gratuity / Tip: Our guides are expected to go above and beyond for this trip and greatly appreciate any & all gratuities.
