Grand Canyon, Flagstaff & Sedona: Colorado Plateau in Three Days

A 400-foot-deep limestone canyon east of Flagstaff with 25 accessible Sinagua cliff dwellings built into natural alcoves in the canyon walls between 1100 and 1250 CE. The Island Trail (1 mile, 185 steps down and back up) passes directly past 25 rooms in the alcoves — close enough to see the original mud plaster and handholds worn into the rock. Unlike many cliff dwelling sites where you view from a distance, Walnut Canyon puts you at the level of the rooms. The Rim Trail above (0.7 miles, flat) provides an overview perspective of the canyon structure.

Flagstaff's historic downtown still runs along the original alignment of Route 66 — the mother road passed through the city center before the interstate bypass. Heritage Square and the pedestrian blocks around the Santa Fe Railroad depot have preserved the 1920s-1940s brick commercial vernacular; the Weatherford Hotel (1900, Italian Renaissance facade) is the most prominent building. Flagstaff sits at 6,900 feet in the Ponderosa pine forest, making it noticeably cooler than Phoenix in any season. The NAU campus and the Museum of Northern Arizona (Navajo, Hopi, and Zuni collections — best such collection in the Southwest) are within walking or driving distance.

The 1894 private observatory on Mars Hill where Clyde Tombaugh discovered Pluto in February 1930 using the 13-inch astrograph telescope (still on display). Percival Lowell founded the observatory to study Mars; his detailed observations of what he believed to be Martian canal networks were controversial in his time and wrong, but his telescopes also produced the first accurate measurements of galaxy recession velocity that contributed to Hubble's expansion of the universe discovery. Daytime tours visit the 1896 Clark Refractor (24-inch, one of the most historically significant telescopes in America) and the Pluto discovery telescope dome; evening sessions offer live sky viewing.

A 1927 downtown Flagstaff landmark — built by a public stock sale after the community decided the city needed a proper hotel; rooms named after John Wayne, Bob Hope, Humphrey Bogart, and other celebrities who stayed here during the Route 66 era. Central location on San Francisco Street, walking distance from Lowell Observatory and the Route 66 restaurant strip. Tomorrow's Grand Canyon drive is 1 hour north on US-180 or AZ-64.

Mather Point is the South Rim's main orientation overlook — the first viewpoint most visitors reach, with a paved amphitheater-style terrace above a 1,000-foot vertical drop to the Tonto Platform below. The canyon at this point is 10 miles wide rim-to-rim and 5,249 feet deep; the Colorado River appears as a thin brown line 4,500 feet below. The Grand Canyon Visitor Center 200 yards behind the overlook has the best introductory exhibits on the canyon's geology (2 billion years of rock layers exposed), ecology, and Ancestral Puebloan occupation.

The historic Grand Canyon Village at the top of the Bright Angel Trail — the trail used by the Havasupai for centuries before Fred Harvey's company built the 1905 El Tovar Hotel and the 1935 Mary Colter-designed Bright Angel Lodge directly on the rim. El Tovar is a National Historic Landmark: log and native stone construction, the only hotel on the rim with actual canyon-view rooms. The Bright Angel Lodge has a geological fireplace built by Mary Colter using rocks collected from each of the canyon's geological strata in sequence from the floor up. Lunch at the El Tovar dining room is booked well ahead; the Arizona Room at Bright Angel Lodge is easier.

Hermit Road runs 7 miles west from Grand Canyon Village along the South Rim — accessible by free NPS shuttle (no private vehicles March–November). Hopi Point is the most-visited sunset viewpoint on the South Rim, with a long unobstructed view up and down the Colorado River corridor. The Abyss, 2 miles west, is a sheer 3,000-foot drop-off with a different canyon geometry — the Great Mohave Wall rises straight across. Powell Point has the canyon's memorial to explorer John Wesley Powell. The full round trip takes 2-3 hours by shuttle with stops.

The 1905 National Historic Landmark hotel directly on the Grand Canyon South Rim — the Fred Harvey Company's flagship property, built in a style combining Swiss chalet and Norwegian villa influences with the native stone and timber of the canyon country. Rooms sell out a year in advance for the canyon-view category; the Village area rooms are booked 6 months ahead. Bright Angel Lodge (adjacent, also historic, lower price) is the alternative. Tomorrow's Desert View Drive starts from the South Rim Village east.

Mary Colter's 1932 70-foot stone watchtower at the eastern end of Desert View Drive — inspired by Ancestral Puebloan towers at Hovenweep and Mesa Verde, built with the participation of Hopi artists who painted the interior murals. The watchtower gives the most expansive canyon view available from the South Rim: the Colorado River bends visible in both directions, the Painted Desert begins beyond the canyon's north wall, and on clear days the San Francisco Peaks above Flagstaff are visible to the south. The viewpoint in the morning catches the light differently than the sunset-oriented west-facing overlooks.

A 1956 Roman Catholic chapel cantilevered into the red sandstone cliffs south of Sedona — an architect-designed building integrated into the rock formation rather than placed beside it. The drive south from Desert View through Cameron and then Oak Creek Canyon (US-89A, one of the most scenic highway descents in Arizona) arrives at Sedona through the canyon rather than from the desert, which gives a dramatic introduction to the red rock formations from above.

The Spanish colonial-style arts complex off AZ-179 south of Uptown Sedona — sycamore-shaded courtyards with 45 independent galleries. The Cathedral Rock view from the Bell Rock Vista parking area nearby is one of the most photographed scenes in Arizona: the twin-spired red sandstone formation rising above a curve of Oak Creek. The return drive to Phoenix on I-17 takes about 2 hours from Sedona.
