Boulder Gulch - South Fork Trail Junction

Hike the moderate 6.8-mile Tower Mountain via South Fork Trail, gaining 2124 feet to alpine meadows and the summit in under four hours.

Prepare for a challenging alpine hike on the Boulder Gulch Trail, a difficult route spanning 14.8 miles (23.9 km) with a significant elevation gain of 5015 feet (1528 metres). You can expect to spend around 8 hours and 49 minutes navigating its varied terrain. The journey begins with a gentle ascent through quaking aspen groves, gradually transitioning to a steep climb. As you gain altitude, you will encounter refreshing waterfalls and eventually reach a high pass situated between Storm Peak and Tower Mountain, offering expansive views of the surrounding wilderness. The trail culminates at Velocity Basin, where a serene alpine lake reflects the towering peaks, providing a classic high-country vista.

This remote and high-elevation trail demands careful preparation. Be aware that you might encounter snow patches even in mid-June, and above 12,000 feet, the path can become faint, requiring careful navigation through scree fields. Always check the weather forecast for potential thunderstorms before you start, as exposure to lightning is a risk. This is a hardcore alpine experience, so plan your visit accordingly to ensure a safe and enjoyable trip.

Boulder Gulch Trail is nestled within the San Juan National Forest, offering a true wilderness experience away from crowds. Its challenging nature and remote setting make it a notable route for experienced hikers seeking solitude and dramatic high-country scenery. The trail's journey through diverse landscapes, from aspen forests to alpine passes and basins, showcases the rich natural environment of this mountainous region.
