The bridge at the site was designed as a rainbow-arch style structure, which gives the location its name.
The site served as a major thoroughfare for early motorized travelers moving through Ute Pass before the construction of modern highway bypasses.
The water is part of the Fountain Creek watershed, which flows through the heart of Colorado Springs.
Geologically, the canyon exposes layers of Fountain Formation sandstone common to the Front Range.
Rainbow Falls Historic Site is defined by the iconic 19th-century concrete arch bridge spanning Fountain Creek. The site features a notable 40-foot waterfall that creates a plunge pool frequently used by visitors for swimming. Originally constructed in 1923, the bridge is listed on the National Register of Historic Places and represents early U.S. Highway 24 infrastructure. The trail leading to the falls is short and primarily follows the creek bed, requiring navigation over rocks and uneven terrain. The area serves as a popular geologic point of interest in the Manitou Springs region. Visitors often encounter graffiti on the surrounding canyon walls, which contrasts with the natural cascade. Due to the narrow canyon environment, the water levels fluctuate significantly based on upstream mountain runoff and weather conditions.
Position yourself on the north side of the bridge looking south to capture the arch framing the waterfall.
Wear water shoes or sandals with secure straps to navigate the rocky creek bed comfortably.
Bring a waterproof bag for your phone and keys if you intend to swim in the plunge pool.
Visit during mid-week to avoid crowds, as the limited parking area fills quickly on weekends.
Do not attempt to park on the shoulder of the highway or in unofficial areas, as vehicles are frequently ticketed or towed for safety violations.
The site is occasionally closed during periods of heavy flash flood risk or for maintenance; check local El Paso County community services alerts before departing.
Practice Leave No Trace principles; pack out all trash and respect the historical integrity of the bridge structure by not climbing on the masonry.
