Tonahutu Trail to Big Meadows - 8.4 Miles Round-Trip

The Tonahutu Trail is accessible from the North Inlet Trailhead at Grand Lake, and the Kawuneeche Visitor Center via the Tonahutu Spur.

It arcs 13 miles northeast to Flattop Mountain on the Continental Divide, forming the western half of the most popular thru-hike in Rocky Mountain National Park.

While few tackle the Tonahutu in its entirety, many use it to access Big Meadows, an aptly named expanse that supports large numbers of elk and moose. The Tonahutu route into Big Meadows is longer than beginning at Green Mountain Trailhead, but preferable for lighter crowds and a particularly active wildlife corridor along the creek.

Mild grades and good trail conditions are ideal for families, backpackers and winter recreation, and anglers will enjoy easy access to deep oxbows in a pastoral setting. The following description begins at the Kawuneeche Visitor Center on the Tonahutu Spur:

The trail heads east through dense lodgepole to join the main Tonahutu Trail at .65 miles (8,695’). The Tonahutu Trail steepens past Harbison Ditch (.8 miles), then levels for an extended period.

Though the canopy is badly marred by beetle kill, the forest floor is brightened by flowers and a verdant herbaceous layer. Deadfall creates useful viewing lanes, and late-summer travelers will enjoy mushrooms and raspberry patches along the way.

Tonahutu Creek is first visible at 1.1 miles, where the forest gradually opens and diversifies. Medium-sized meadows appear at 1.7 and 2.2 miles before a third opening reveals a long, open corridor that you’ll follow into the main meadow (3.0 miles : 9,325’).

The trail enters a contrastingly healthy swath of moss-draped fir to the Paintbrush backcountry campsite (3.55 miles : 9,265’), then edges up against the meadow (3.9 miles). Use this partially concealed segment to look for elk, moose and bear in open space.

The trail passes a spur for South Meadows and Big Meadows Group campsites (4.05 miles : 9,390'), which crosses Tonahutu Creek to the east side of the meadow. A few steps ahead is the Green Mountain Trail junction on the northwest corner of Big Meadows (4.2 miles : 9.397’).

Those with time should continue on the Tonahutu Trail a bit longer for exceptional views and additional perspective on the route you took to this point.

Worth Noting

  • Enjoy wildlife from a distance. Moose in particular can be dangerous if startled, with calves or during the rut. Moose have poor eyesight, a deficiency that may contribute to negative encounters.
  • The 2013 Big Meadows Fire was started by lightning on June 10. It burned about 610 acres before containment, with minimal impact on the meadow-proper.
  • The Tonahutu Trail sees heavy equestrian travel. Honor yield protocols for horses.
