Alaska is considered to be a birthplace of packrafting. This great activity involves little packable boats that weight less than two kilos and can be easily carried around during your trip in the Alaskan wilderness. If you are a not a very experienced hiker, it's better to join a guided tour to Wrangell–St. Elias National Park and Preserve, Nizina River and glacier or Lakina River, beneath the Castle Mountain and Mount Blackburn. Arctic National Wildlife Refuge offers plenty of sights for a multi-day packrafting trip.
