Glacier National Park is often described as a "hiker's paradise," and over 700 miles of trails offer plenty of choices for what the park describes as "adventurous visitors seeking wilderness and solitude." Glacier also offers some fine shorter hikes that offer a taste of the backcountry with only moderate physical demands, and one of the most popular is the combination boat trip/hike to Grinnell Lake.

Mountain goats are spectacular animals, even iconic in places such as Glacier National Park, but they can cause problems in parks where they don't belong. At Olympic National Park, where a 1920s era introduction project brought non-native goats into the landscape, officials are embarking on a management plan for how to deal with the animals. Adding weight to the need for such a plan was the fatal goring of a hiker in the park four years ago.
