Overview: Walnut Canyon is a scenic limestone gorge located just east of Flagstaff and preserved as a National Monument. While not a canyoneering route, it offers a unique opportunity to explore a canyon environment combined with significant archaeological history.

The canyon is known for its well preserved cliff dwellings built by the Sinagua people around 1100 to 1250. Visitors can access these ruins via maintained trails that descend into the canyon.

This is a highly accessible canyon experience suitable for all skill levels, but it should be considered a hiking and historical site rather than a technical or exploratory canyon route.

Approach: From Flagstaff, head east on I-40 to Exit 204 and follow signs to Walnut Canyon National Monument. Drive to the Visitor Center where parking and facilities are available.

Route Description: The primary route is the Island Trail, a paved loop that descends into the canyon and circles a large rock formation containing numerous cliff dwellings.

The trail includes a significant number of steps and elevation change, making the return climb moderately strenuous despite the short distance.

The Rim Trail provides a less strenuous alternative along the canyon rim with overlooks into the canyon. Walnut Creek is typically dry or seasonal due to upstream water control and changing climate conditions. Expect dry conditions throughout most of the year.

Exit

• Island Trail: Complete the loop and return to the Visitor Center
• Rim Trail: Out and back along the canyon rim
