Granite Falls - 10.3 Miles Round-Trip

Granite Falls is accessible from the Green Mountain Trailhead on the west side of Rocky Mountain National Park. The falls fan out over three tiers and several large boulders accessible from the trail. Visitors will enjoy mild grades, tranquil forests, a stop at Big Meadows, excellent wildlife viewing, and numerous backcountry campsites on the hike to Granite Falls:

The Green Mountain Trail heads east on moderate grades through a heavy fir-forest and lush understory. Peripheral meadows are ideal places to see moose and elk. Travel quickens on level grades to the edge of Big Meadows, Lower Tonahutu Trail split, and Big Meadows Backcountry Campsite (1.8 miles : 9,397').

Follow signs left on a level path for 1.2 miles around the northwest side of Big Meadows. Big Meadows is an immense, marshy expanse ideal for seeing wildlife and enjoying sheer open space.

A number of spurs provide easy access to the meadow's open perimeter. The trail wraps west to the northeast edge of Big Meadows and resumes travel in a thick fir-lodgepole forest (3.0 miles : 9,441').

The trail reaches Tonahutu Creek (3.35 miles : 9,446'), which you'll closely follow for the next 3.45 miles. The trail rises nominally to a spur for Sunset Backcountry Campsite (3.8 miles : 9,495'), just past which the forest breaks with access to a long oxbow in the creek. Sunrise Backcountry Campsite is located on the east side of this meadow (4.05 miles : 9,511').

The trail undulates in a thick, mixed forest through 4.5 miles (9,565'), then steepens on a rougher path to Lower Granite Falls Backcountry Campsite (5.05 miles : 9,748') and Granite Falls (5.2 miles : 9,785').

Granite Falls fan out and tumble about 20' before narrowing through a series of forceful chutes. A short, steep scramble leads down to outcrops with up-close views on the water's edge.

The trail switchbacks over the falls to Granite Falls Backcountry Campsite (5.35 miles : 9,921'), located on the edge of a large, wet sedge meadow, another good place to look for moose.

Worth Noting

  • Granite Falls are steep and swift. Maintain a safe distance from the falls and slick rocks that line it.

  • The west side of Rocky Mountain National Park receives a foot or more of rain per year than the east side of the Park. As a result, west side trails are generally more verdant than east side trails.

  • You may continue on from Granite Falls to Haynach Lakes, or up the Continental Divide to Flattop Mt.
