The Best Summer Hikes in Alaska

Covering more than 665,000 square miles, Alaska is massive. Earning the number one spot for being the largest state in the United States, Alaska’s landscape is still untouched and remote, accounting for two-thirds of the country’s national parklands, roughly 80% of wildlife refuges and houses the two largest national forests. For most, these numbers are incomprehensible, so, to put it simply, Alaska offers more outdoor adventures than any other state. Making Alaska one of the most diverse places to hike in the United States. But, which hikes should you start with?

The best summer hikes in Alaska are:

  • Byron Glacier Ice Cave Hike

  • Grewingk Glacier Lake Hike

  • Rainbow Lakes Hike near Kenai Lake

  • Chutes and Ladders Hike

  • Exit Glacier and Harding Icefield Hike
