It can be much quieter in June and September, and the same principle applies in earlier morning or later day—better chance for wildlife viewing, more space to yourself and no crowds to avoid.

Instead of trying to check everything off a giant list in a sprawling place like Alaska, we suggest you focus in on one element. It could be taking photos of the sunset in each park, hiking the most iconic trails, or adding flowers to your life-long flora list.

Never feed any wild animals, including birds. Grizzly bears and moose are unpredictable and dangerous. Get informed and fully understand how to safely travel in these wilderness areas before you come. Stop by the visitors’ center (see #5) for up-to-date information.

If you think about dressing like an onion—with layers you can peel or add on depending on the conditions—you’ll be prepared. No matter what, dress for the worst.

There’s some essentials you need (see our packing list). But there’s lots you don’t need.

The rule is to leave the park better than you found it—so pick up trash and do not ever feed the wildlife.

Every time you arrive at a national park, make your first stop a park visitors’ center. You’ll get the latest updates on road and trail conditions, be pointed towards a little-known spot to maybe spot some moose, and learn about the natural history from the experts. You can also sign up for a ranger-led naturalist hike and pick up the latest edition of the park newspaper.
