Green Mountain Trail

Overview

This short west-side classic climbs through cool conifer forest to the edge of Big Meadows, one of Rocky’s broadest valley clearings. It’s 3.5 miles total (out and back) with about 731 feet of gain, topping out at the junction by the South Tonahutu/Big Meadows and Onahu Creek trails. The route also overlaps the Continental Divide National Scenic Trail corridor, so you get a little taste of a long-distance route without committing to a big day.

Trail Experience

From Green Mountain Trailhead, the first half-mile bites: roughly 321 feet of gain on timber-and-dirt steps and a steady grade. Catch your breath—after that, the climb eases into a more forgiving ascent beneath spruce and fir. You’ll follow and cross near a creek as the forest opens into the edge of Big Meadows, an expansive, photogenic grassland ringed by dark timber and distant gray peaks. In summer, expect wildflowers in the clearings and along moist sections of trail. Reviewers frequently report wildlife sightings here; moose are the headliners, especially at dawn, dusk, and the couple of hours before sunset.

Difficulty and Conditions

Despite the modest mileage, the altitude (trailhead just under 8,800 feet) and that initial pitch make it feel like a real hike. Plan for sun on a few open stretches, and for wet or muddy patches after rain—walking straight through the mud protects trail edges. Seasonal notes have included downed trees near Big Meadows and lingering early-season snow at higher elevations in the region; this route is typically clear by early summer but can change fast with monsoon storms.

When to Hike

Mornings are best for parking, cooler temps, calmer winds, and wildlife. Summer afternoons often bring thunderstorms; aim to be headed down by early afternoon. Late spring through early fall offers the friendliest conditions and wildflowers; winter turns this into a worthy snowshoe if you’re prepared.

Wildlife and Natural Notes

Keep an eye on the meadow edges and willow-choked creek lines for Moose. Elk and Mule Deer browse the forest margins, and you’ll see (and hear) plenty of small critters like chipmunks along the way. You may notice areas of dead or dying conifers from bark beetle activity—a widespread forest health issue across the West.

Tips, Extensions, and Logistics

• Short on time? Turn around at the Big Meadows junction for the classic 3.5-mile outing. Feeling strong? Continue a bit along the Tonahutu Creek Trail toward Granite Falls for a longer day—just check conditions before you commit.
• Start early, wear sturdy footwear, and pack a light rain layer even on bluebird mornings. Bring extra water; the first climb is no joke at altitude.
• Facilities: There are restrooms at the trailhead, but the small lot can fill. Arrive early in peak season.
• Regulations: Backcountry camping near Big Meadows requires a paid permit. Pets are not allowed on park trails. Fire restrictions commonly limit campfires to designated front-country rings. Check for current west-side project closures before you go.
