The Chugach, Wrangell, and St. Elias mountain ranges converge here in what is often referred to as the mountain kingdom of North America. The largest unit of the National Park System and a day's drive east of Anchorage, this spectacular park includes the continent's largest assemblage of glaciers and the greatest collection of peaks above 16,000 feet. Mount St. Elias, at 18,008 feet, is the second highest peak in the United States.

Leashed pets are permitted in the park, but are not allowed in the buildings. Leashes must be no longer than six feet. Visitors are advised to be aware of wildlife and loose dogs owned by local residents.

From pet-traveler Ana: "There are two roads (gravel, remote access) to access the park and one coastal access (by boat). We went on the Nabesna Road, a 42 mile partially mantained road. A few trailheads of trails of diverse difficulty can be found along the road and there are are also a few pullouts where it is allowed to camp (there is also a small campground).

Services are limited to vaulted toilets.

We had an amazing time and as always in NP views are amazing. Plenty of creeks where pups can cool down while hiking. We have a senior girl and not all trails are suitable for her but we adapt to that and it was a wonderful trip. It is a National Park and Preserve and in the Preserve portion sport hunting is allowed (under Alaska regulations) so I would not recommend visiting during moose hunting season (which in fact starts somewhere in the second or the third week of August).

The McCarthy road is also remote but somewhat more popular because it allows to reach the tiny town of McCarthy and the Kennecott Mine Historical Area. We have not visited it yet but as far as I know the there is at least one pet friendly campground in McCarthy and I think that another inside the limits of the park. However, the access between McCarthy and the Mine (where most of the trailheads, including the one that takes to a glacier) is not open to private vehicles, only for residents. Sadly, the shuttles are no longer pet friendly."
