20 Day Alaska Itinerary, incl. Anchorage and Denali National Park

- Days 1-4
Anchorage & Seward
Your Alaska adventure begins in Anchorage, where summer brings 18-20 hours of daylight and pleasant temperatures of 58-77°F. Take a 2.5-hour drive to Seward on day 2. "Watching the calving glaciers in Kenai Fjords was mind-blowing - bring a warm jacket even in summer as the wind off the water gets chilly," notes a recent visitor. Take two days to explore Exit Glacier. If you're up for it, tackle the full 8.2-mile Harding Icefield trail, or choose shorter viewpoint hikes. Look out for black bears snacking on berries near the trail.

Denali National Park
A must-see on any Alaska trip. Take an early morning park shuttle into the wilderness for the best wildlife viewing. "Layer up - temperatures can swing 30 degrees in a day. The mosquitoes are fierce in summer so bring repellent," suggests one traveler. Book a flightseeing tour around Mt. Denali if weather allows.

What people love about 3-week USA tours
- Alaska Adventure - 20 Days
After experiencing a few Overlandtrips in different parts of the world I have to say this was definitely by far the best. Everything planned to the detail by absolutely commited guides (Nat & Dave) so we didn`t have to worry about anything. This in addition to the beautiful country and wildlife made it just the perfect trip to free the mind and have some great adventures. Thank you very much guys - hope I will have some time soon to join for another trip.
- Ultimate Western USA
The tour was good. Loads of stops and really great experiences and views along the way. This trip is actually quite active so I don't think the skill rating is accurately reflected on the overview.

The tour guide, John, made the trip fun, entertaining, and he was so knowledgeable of the route
