Bluebird Lake

Overview

Bluebird Lake is a long, strenuous out-and-back to a high alpine cirque tucked beneath Ouzel Peak on the Continental Divide. Expect about 13.3 miles total with roughly 2,700–3,000 feet of gain, and plan 6–8 hours depending on pace and stops. The payoff is big alpine drama at roughly 10,980 feet, but you earn it with steady climbing and a rocky, steep finale.

What You’ll See

From the Wild Basin Trailhead, the route follows the North Fork of the St. Vrain River through subalpine forest, with optional short spurs to Copeland Falls, Calypso Cascades, and Ouzel Falls—great morale boosters on the way up. Higher, the trail traverses the west wall of the canyon through open country (including the 1978 Ouzel Fire area) with expanding views and wildflowers in season. The final approach tops out above a stark cirque basin with Bluebird Lake framed by Ouzel Peak and neighboring summits.

Trail Character and Challenges

Footing is generally good early, but expect rocky sections and several side stream crossings. The last 1–2 miles are notably steeper and more rugged with limited shade. A narrow upper gulch can hold snow well into summer, and a short bit of scrambling/boulder-hopping is often required to actually reach the lakeshore. In high runoff, crossings near Ouzel Creek can be wet.

Logistics and Rules

Start at the Wild Basin Trailhead, which has a medium-sized lot—arrive early to park and to beat crowds. Park entry fees apply, and timed-entry reservations are typically required during peak season. Pets are not allowed on park trails. Toilets are at the trailhead; drinking water may be available in season. Backcountry camping is by permit only at designated sites; you’ll pass the Upper Ouzel Creek campsite near the start of the final climb (also the stock limit for horses).

Timing and Tips

Best season is roughly late spring through fall, with the most reliable snow-free conditions in mid to late summer. Shoulder seasons can mean lingering snow/ice up high—traction can help. Start early for cooler temps, steadier weather, and a quieter trail; afternoon thunderstorms are common. Carry plenty of water and calories—this is an all-day effort—and be ready for altitude if you’re coming from lower elevations.

Is It For You?

If you like a big, varied day—waterfalls, fire-scar views, and a dramatic alpine finish—this delivers. If the mileage feels a bit much, consider turning around at Ouzel Falls for a shorter day, or take the signed spur to Ouzel Lake for an easier lake payoff. Strong, experienced hikers sometimes continue beyond Bluebird toward Isolation Lake on rough, minimally marked terrain—only if you have the skills, time, and navigation tools.
