As one of the most popular trails in the park, runners should be aware of the heavy foot traffic one would encounter in the middle of the day. To avoid the crowds, start before 11:00 AM or after 4:00 PM.
As you drive into the Many Glacier area of the park, there's only one road to take. You'll drive along Swiftcurrent Lake for a while, until you come upon a parking area on your left for the Grinnell Glacier
Trailhead. (Another way that some people start the trail is by boat, which can be picked up at the Many Glacier Hotel a little farther down the road. Taking the boat shaves off around 3.4 miles roundtrip).
Starting from the trailhead, the first two miles are mostly flat, taking you along Josephine Lake before you reach a fork in the trail. The trail to the left is the Josephine Walk
to the Grinnell Lake Trail
, and the trail to the right is the Grinnell Glacier
Trail. Just after the junction, you start going up. There are spectacular views of Grinnell Lake
to the south, with Mt. Gould standing tall behind it. As you run, you'll pass fields of wildflowers, waterfalls, and with any luck some wildlife! The trail does at points get narrow, and those with mobility restrictions should be aware of the steep nature of some points of the trail. That being said, families of all ages take the trail every summer, so be sure to bring appropriate supplies (hiking poles, water, food, etc.).
Looking into the Grinnell Basin as you approach you'll see two glaciers, Salamander and Gem, settled into the rock face. Eventually, you'll reach the glacier itself, affording a spectacular view of Grinnell. Settle into one of the best lunch spots in the park, and enjoy the view before starting back!
This trail also offers Ranger-led hikes starting oftentimes in July, be sure to check out Glacier's website
is one of the best trails in the park to spot wildlife and wildflowers. Glacier Lillies, Beargrass, and Western Pasque Flowers surround runners with each footstep. Mountain goats, marmots, and even moose or grizzlies can be seen from this trail. The Many Glacier area of the park is famous for it's wildlife sightings, so bring your binoculars!
