South Coldwater and Lakes Trail Loop

This loop is generally considered difficult. It covers approximately 11.5 miles (18.5 km) with significant elevation gain, around 1,700 feet (513 m). Hikers will encounter varied terrain, including old logging roadbeds, steep climbs through forests, and potentially brushy or exposed sections. One part involves gaining about 1,500 feet in just two miles, making it a challenging endeavor.

Due to its length, significant elevation gain, and challenging terrain, the full South Coldwater and Lakes Trail Loop is not recommended for beginners or young children. It's best suited for experienced hikers with good physical fitness. However, shorter, easier sections of the Coldwater Lake Trail might be more suitable for families looking for a less strenuous experience in the area.

The trail offers incredibly diverse terrain and scenery, showcasing the powerful impact and recovery from the 1980 Mount St. Helens eruption. You'll traverse young forests of alder and willow, ash-pocketed slopes that bloom with wildflowers, and sections of old logging roads. As you climb, expect breathtaking panoramic views of the Mount St. Helens crater, Coldwater Lake, Coldwater Peak, and Johnston Ridge. The landscape is a striking mix of scarred terrain and remarkable natural regeneration.

A truly unique aspect of this trail is its direct connection to the 1980 eruption. You'll encounter rusting remains of logging equipment, such as bulldozers and yarding towers, left exactly where they were destroyed by the volcanic blast. These artifacts serve as powerful reminders of the eruption's force. Coldwater Lake itself is a post-eruption formation, offering a unique perspective on the area's recovery.

The Mount St. Helens area is known for its wildlife, and elk are frequently spotted in this part of the monument. Keep an eye out for other forest animals and a variety of bird species as you hike through the regenerating landscape.
