The next year, on May 30, 1910, U.S. President William Howard Taft used presidential proclamation to designate Rainbow Bridge National Monument. Teddy Roosevelt and Zane Grey were among the first visitors to make the trek by foot and horseback from Oljeto or Navajo Mountain. In 1924 S.I. and Hubert Richardson built a road north from Red Lake (Tonalea) to the west side of Navajo Mountain, where they built a rustic stone building and facilities for mules and visitors, calling it Rainbow Lodge. They established a trail from the lodge to Cliff Canyon, then over Redbud Pass to Bridge Canyon. The 14-mile trip from the lodge to Rainbow Bridge could be made in one day by mule or horse. Bill and Catherine Wilson operated the lodge from 1928 to 1951, except for the World War II years. In 1942 Barry Goldwater (later US Senator and presidential candidate) acquired a half interest in the lodge. The main building at the site burned in August, 1951. Merritt and Winona Holloway operated the lodge in 1952, using a garage building as a dining hall. Miles Hedrick conducted some trips from the lodge site for the next few years, before the site was abandoned. The site is now the trailhead for hikers to the bridge. Due to erosion, Redbud Pass is no longer passable for horses.
