Heli Rafting

$699.00 per person

Our most exclusive and remote rafting tour! 
A 6-hour full day Heli Rafting Alaska adventure, from mountain glacier headwaters to the Turnagain Arm ocean.

Access the remote glaciated Chugach Mountains with Alpine Air Alaska; there is no better view than from a Robinson R44 helicopter.  Buzz the Twenty Mile Glacier and see the grand scope of the Chugach Mountains.  Land on the iceberg-laden Twenty-Mile Lake for your private Alaska raft adventure down Twenty Mile River.  Float 12 stunning miles downriver to an ocean pick-up on Turnagain Arm at the Seward Highway. Keep a good look out for wildlife: bears, moose, bald eagles, and salmon.

My favorite aspect of this trip is how few people actually visit 20-Mile Glacier, but those who do, get to experience raw, untouched nature – it is truly breathtaking upon arrival.  – Justin Siemens – Chugach Adventures’ Operations Manager and Guide Since 2012.  Born & Raised in Anchorage, AK.

    Our guides favorite river to run! We don’t do many Heli Rafting floats during a season, but all trips out here are unforgettable. There are few river systems that you can float in one day from the Glacier Headwaters to the Turnagain Arm Ocean.

  2. Ari Stiassny

    Customizable overnight camping trip available on this tour as well. Helicopter Flight, Delicious food, outfitted camping, and rafting all in one. The extra time and overnight will enable you to connect to 20 Mile Glacier all the more intimately. Our guides love to spend the night at 20 Mile and hope you can join us for an overnight in the near future!
