Starting at the Bear Lake Trailhead, this hike quickly immerses you in the soft rustle of aspen groves, their golden leaves beckoning with a quiet invitation. The path climbs steadily up the Bierstadt Moraine, where Longs Peak peers over the horizon—a granite giant watching over the landscape. Moving beyond the moraine, the trail dips into dense forest and follows the murmuring Mill Creek Drainage, a waterway that seems to dare you onward with every ripple.

A short detour leads to Two Rivers Lake and Lake Helene, two subalpine jewels framed by rugged ridges like Notchtop and Ptarmigan Point. These lakes mirror the sharp edges of their surroundings, creating a moment of calm reflection before the hike challenges you again. From here, descending into Odessa Gorge reveals an elemental contrast: Grace Falls crashes beneath sheer cliffs, water rushing as if thrust forward by the mountain itself. The vista opens, offering unobstructed views of Little Matterhorn and The Gable, rocky spires that sharpen the sky.

By the time you arrive at Odessa Lake, just over four miles in, the effort feels earned. The lake sparkles with clarity, held within a basin carved by ancient forces and surrounded by peaks that keep watch. This is the mountain’s theater—raw, grand, and fiercely alive.

To extend the experience, plan a two-car shuttle: park one at Bear Lake and the other at Fern Lake Trailhead. From Odessa Lake, continue down toward Fern Lake, passing through the East Troublesome Fire’s burn scar—a stark, powerful reminder of nature’s cycles. Along the way, Fern Falls, the Pool, and Arch Rocks demand attention with their unique character before ending at Fern Lake Trailhead. The full loop stretches nearly 10 miles, blending forest, waterfalls, alpine lakes, and expansive views into one signature Rocky Mountain adventure.

Prepare for variable terrain, from well-maintained paths to rugged sections through the burn area. Hydration, sturdy footwear, and timing your hike to avoid midday heat or afternoon storms will keep the experience comfortable and safe. This route challenges with its length and elevation but rewards each step with vivid encounters and landscapes that embody the Rockies’ true spirit.

Whether you’re after a day of exploration or a full mountain immersion, the Bear Lake to Odessa Lake hike offers a crisp balance of adventure and accessibility—raw nature that invites respect and rewards persistence.
