Hiking

With more than 730 miles of marked trails, Glacier is a hiker's paradise. Trail maps are available at all visitor centers and entrance stations. Before hiking, ask about trail closures due to bear or mountain lion activity. Never hike alone. For backcountry hiking, pick up a permit from park headquarters or the Apgar Backcountry Permit Center (406/888–7939) near Glacier's west entrance.

Easy

Baring Falls. For a nice family hike, try the 1.3-mile path from the Sun Point parking area. It leads to a spruce and Douglas fir woods; cross a log bridge over Baring Creek and you arrive at the base of gushing Baring Falls. Easy. Glacier National Park, Montana.

Hidden Lake Nature Trail. Hidden Lake Overlook is an easy, 1½-mile hike from the Logan Pass Visitor Center. Along the way, you'll pass through beautiful alpine meadows known as the Hanging Gardens. Enjoy incredible views of Hidden Lake, Bearhat Mountain, Mt. Cannon, Fusillade Mountain, Gunsight Mountain, and Sperry Glacier. It's common to see mountain goats near the overlook. If you want a challenge, continue hiking all the way down to the edge of the lake—a moderate 5.4-mile round-trip hike. Easy to moderate. Glacier National Park, Montana.

Sun Point Nature Trail. A stunning waterfall awaits at the end of this well-groomed, 1.3-mile trail along the cliffs and shores of picturesque St. Mary Lake. You can hike one-way and take a boat transfer back. Easy. Glacier National Park, Montana.

Trail of the Cedars. This ½-mile boardwalk loop through an ancient cedar and hemlock forest is a favorite of families with small children and people with disabilities (it's wheelchair accessible). Interpretive signs describe the habitat and natural history. Easy. Glacier National Park, Montana.

Moderate

Highline Trail. From the Logan Pass parking lot, hike north along the Garden Wall and just below the craggy Continental Divide. Wildflowers dominate the 7.6 miles to Granite Park Chalet, a National Historic Landmark, where hikers with reservations can overnight. Return to Logan Pass along the same trail or hike down 4½ miles (a 2,500-foot descent) on the Loop Trail. Moderate. Glacier National Park, Montana.

Iceberg Lake Trail. This moderately strenuous, 9-mile, round-trip hike passes the gushing Ptarmigan Falls, then climbs to its namesake, where icebergs bob in the chilly mountain loch. Mountain goats hang out on sheer cliffs above, bighorn sheep graze in the high mountain meadows, and grizzly bears dig for glacier lily bulbs, grubs, and other delicacies. Rangers lead hikes here almost daily in summer, leaving at 8:30 am. Moderate. Glacier National Park, Montana.

Difficult

Grinnell Glacier Trail. In 1926, one giant ice mass broke apart to create the Salamander and Grinnell glaciers, which have been shrinking ever since. The 5½-mile trail to Grinnell Glacier, the park's most accessible, is marked by several spectacular viewpoints. You start at Swiftcurrent Lake's picnic area, climb a moraine to Lake Josephine, then climb to the Grinnell Glacier overlook. Halfway up, turn around to see the prairie land to the northeast. You can cut about 2 miles (each way) off the hike by taking scenic boat rides across Swiftcurrent Lake and Lake Josephine. From July to mid-September, a ranger-led hike departs from the Many Glacier Hotel boat dock on most mornings at 8:30. Difficult. Glacier National Park, Montana.
