Exploring Long Canyon: Boulder's Hidden Forested Gem

Nestled in Boulder’s Open Space and Mountain Parks, Long Canyon offers a surprisingly lush escape—a short yet richly rewarding hike that stands in stark contrast to the arid foothill surroundings.

Distance: 1.5 miles with significant elevation change approximately 905 feet making this a moderately strenuous yet manageable out-and-back adventure.

Difficulty: Rated hard by the City of Boulder with steep sections that are icy during the winter. Trekking poles are recommended and from October to March microspikes or snowshoes are recommended .

Trail Width: 1-3 feet.

Access: Head to Flagstaff Road and park at Realization Point. From there, cross the road, follow signs toward Green Mountain Lodge, then look for the Long Canyon Trail signage.

Just a short drive from downtown Boulder, the Long Canyon Trail offers an almost secret forested portal into Boulder’s foothills. Despite its proximity to the city, the hike remains underappreciated—ideal for hikers craving quiet immersion in a lush, verdant setting.

The journey begins near Flagstaff Road. Park at Realization Point, cross the street, and head down toward the old Green Mountain Lodge. Follow signage into a cool, narrow canyon that drops you quickly into shaded pines, aspens, and wildflower-laden clearings.

This small canyon hides an extraordinary botanical treasure: a tiny stand of paper birch trees that survived the Ice Age and now grow among their less ancient neighbors. It’s rare to find these birches in Colorado—and a sign that this trail bridges past and present. The trail feels almost rainforest-like—peaceful, green, and alive.

Though the trail gains between 760 to 900 feet over just 1.5 miles, making it a challenging ascent on the return, it remains approachable for most fit hikers. Just prepare accordingly—icy patches emerge from fall through spring, so microspikes and trekking poles are wise gear for safety.

Wildlife is another delight; bird-song fills the air, and you might catch a glimpse of deer or even wild turkeys as they forage among the undergrowth. Despite its richness, you’ll likely have most of the trail to yourself—even on weekends. With only a handful of hikers reported at 7 a.m., it’s serenity at its finest.

Reach a junction with Ranger Trail, and you’ll open options to extend your journey toward Green Mountain or Gregory Canyon—adding distance, new terrain, and fresh perspectives.

Long Canyon is not just another Boulder hike—it’s a quiet gem. Perfect for a reflective morning walk, a nature-filled escape, or a quick adventure when time is short. With its ecological significance, solitude, and scenic charm, it’s a must for locals and visitors alike seeking beauty off the beaten path.
