Munds Park Summit

Munds Park is not a formally signed mountain pass the way Snoqualmie or Loveland are. It is an unincorporated community on I-17 in Coconino County, and the road reaches its local high point near here, crossing around 6,500 feet before the long drop south toward the Verde Valley. The feature drivers actually care about is the grade south of Munds Park, not a discrete named summit. When people say "Munds Park Summit," they mean this stretch of high country where the cool, snowy Colorado Plateau gives way to the descent into the desert.

For a southbound truck this is the start of a 6 percent grade that runs about 13 miles through S-curves toward Camp Verde. Brakes heat up fast on a pull that long, so AARoads notes drivers are advised to use a lower gear than normal for interstate travel. There is a brake-check station for trucks and vehicles pulling trailers at the scenic view area just south of mile marker 313, overlooking Pine Tank and Cedar Tank canyons. That is the place to stop and set your gear before you commit to the descent. Northbound is the opposite problem: a sustained climb out of the lower country up onto the plateau.

Munds Park is also the last services until Camp Verde when you are heading south, off Exit 322 at Munds Ranch Road and Pinewood Boulevard. It sits roughly 21 miles south of Flagstaff and about 126 miles north of Phoenix, surrounded by the Coconino National Forest. Across the whole I-17 corridor the elevation play is large: the road climbs more than a mile between Phoenix at 1,117 feet and Flagstaff near 7,000 feet, and drops roughly 5,500 feet coming back down. Winter storms close this segment episodically, never on a fixed schedule.

• Studded tires are legal statewide Oct 1 to May 1 (ADOT Know Snow and Ice)

Arizona does not run a numbered chain-level system. There is no R-1, R-2, or R-3 here the way California, Colorado, and Washington post it. ADOT puts up conditional restrictions only when a storm calls for them, and the highway signs read "Chains or 4WD required" when that is in effect. Otherwise ADOT advises snow tires, chains, or studded tires as recommended or required on snowy, icy roads, but does not mandate them on a calendar. Studded tires are legal statewide from October 1 to May 1. There is no published chain-control "season" with start and end dates for this segment, so plan to carry chains through the winter and check the posted restriction before you climb. Closures clear when the storm passes and the road reopens, usually within hours. Check current conditions on ADOT 511 or call 888-411-7623.

Munds Park traces back to about 1876, when rancher William (Madison) Munds drove cattle from Oregon down to Arizona's Verde Valley and used the high meadow, the "park," as summer grazing headquarters. The Munds name stuck to more than the community: it also marks Munds Canyon, Munds Mountain, and the Munds Mountain Wilderness. The permanent Christensen Rest Area at milepost 324 had been closed since 2002 for age and budget reasons, according to the Arizona Daily Sun.

In April 2020, during the COVID-19 pandemic, ADOT temporarily reopened that Christensen Rest Area along with the Parks Rest Area on I-40, exclusively for commercial drivers. ADOT Director John Halikowski said at the time that long-haul truckers were working tirelessly to support the nation during a difficult time. The road's winter closures show up again and again in the record: northbound I-17 shut south of Munds Park on February 2, 2024, with ADOT citing multiple disabled vehicles at milepost 310; a March 2025 storm closed the southbound side at milepost 323 on a Friday afternoon; and on February 18, 2026, the southbound lanes closed near Munds Park around 4:20 p.m. and reopened about an hour and 15 minutes later.
