Colorado River State Historic Park sits along the banks of the Colorado River in downtown Yuma, preserving one of the most important transportation crossings in the American Southwest. This 10-acre state historic site occupies the grounds of the former Yuma Quartermaster Depot, where the U.S. Army supplied military outposts across Arizona and the desert Southwest from the 1860s through the early 1900s.

The park’s restored adobe and wooden buildings house excellent exhibits tracing Yuma’s role as a critical river crossing point — from Native American trade routes and Spanish explorers to steamboat commerce and the arrival of the railroad. The original storehouse, commanding officer’s quarters, and corral office have been carefully preserved, giving visitors a tangible connection to frontier-era logistics and desert survival.

Walking the shaded grounds, you’ll find interpretive displays on Colorado River steamboat navigation, military supply chains, and the diverse communities that shaped Yuma’s identity. The park’s riverside location offers pleasant views and a welcome patch of green in the Sonoran Desert.

With a strong 4.5-star rating across 444 reviews, visitors consistently praise the knowledgeable staff and well-curated museum exhibits. Plan about an hour to explore the buildings and grounds thoroughly.

Best time to visit: October through April, when Yuma’s temperatures are comfortable in the 70s and 80s. Summer heat regularly exceeds 110°F, making outdoor exploration uncomfortable. Winter visitors — and Yuma draws plenty of snowbirds — will find this an ideal morning outing before exploring the nearby Yuma Territorial Prison State Historic Park just up the river.
