Rocky Mountain National Park hikes: Glacier Creek Trail

In 1908, Abner and Mary Alberta “Bert” Sprague built a summer cabin in Glacier Basin. By 1910, they were living in it full time, operating it as a lodge that sat in what is now the Sprague Lake parking lot.

Because of their love for the area and their impact on Glacier Basin – to improve the fishing in the area for his guests, Abner dammed the creek to create the lake – the lake now bears their surname. And because of the busy Sprague Lake Lodge they operated from 1910 to 1940, there are many trails to explore in the vicinity, which became Rocky Mountain National Park in 1915.

One of those trails is the Glacier Creek Trail.

This trail isn’t so much a single trail but a network of paths through the forests surrounding Sprague Lake. Adventurous hikers may want to take the long way around, starting at Sprague Lake, Glacier Basin Campground (if camping) or the Storm Pass Trailhead.

Shorter hikes can be done as a loop around Sprague Lake, up onto the moraine above the lake and down into the forest, taking the turn off to the right rather than heading to Storm Pass Trailhead.

A really wonderful option for a full-day hike is to start at Sprague Lake, pick up the Glacier Creek Trail at the east end of the lake, follow it east into the forest and then turn right to follow it back west again towards Bear Lake.

The network of trails parallel Bear Lake Corridor, navigating past many meadows in this valley, and up to Bear Lake. At Bear Lake, follow the eastern side of the lake to pick up the Bear Lake – Bierstadt Lake Trail, following it to Bierstadt Lake and then down to the Bierstadt Lake Trailhead. From this point, cross the road to the Storm Pass Trailhead and pick the Glacier Creek Trail back up on the forest and head east to Sprague Lake.

At about 8 miles, this loop provides some astonishing views plus many opportunities to see wildlife, like mule deer, snowshoe hare, elk, pine squirrels, northern flickers, Stellar’s jays, dark-eye juncos and many other species of forest-loving birds.

For a shorter trek, take the two-mile loop that starts at the east end of Sprague Lake. Near the bridge, the trail heads down into the forest, snaking through ponderosa pine and past a lush green meadow.

At about a half mile, the trail reaches a junction, where hikers turn right. Follow this trail as it begins to climb up the moraine. In about 500 feet, the trail reaches the Glacier Creek Trail, which runs northeast and southwest. Turn right at this junction to head towards Boulder Brook and Bear Lake.

Follow the trail, which is now the Glacier Creek Trail, for 1.1 miles as it stays along a level path on the moraine through thick forest and above meadows.

At slightly more than one mile, the trail reaches another junction, connecting with the Storm Pass Trail. Make a right at this junction.

Interestingly, the trail crosses the Alva B. Adams Tunnel at this point. This 13-mile cement-lined tunnel passes underneath Rocky Mountain National Park to deliver water from Lake Granby to East Portal on the west side of Estes Park. There are no markers or indicators of what lies beneath the ground but using the COTrex app will show you the path of the tunnel below the trail.
