Slide Rock State Park ends roadside parking queues starting May 1

Slide Rock State Park is ending the familiar Highway 89A backup at the gate. Starting May 1, once the Sedona-area park’s roughly 156-space lot fills, drivers will no longer be allowed to line up on the road and wait for an opening.

That changes the trip for anyone counting on a late-morning arrival. Arizona State Parks says the lot can stay closed for hours or even all day once full, so visitors who miss the first wave may be turned away until spaces reopen. The park opens at 8 a.m. and closes at 5 p.m., and KJZZ reported the site can hold about 165 vehicles. Michelle Thompson, deputy assistant director for Arizona State Parks and Trails, said the roadside queue is dangerous for highway traffic and blocks workers from getting to the park.

The move matters because Slide Rock is not a small local stop. Northern Arizona University’s visitation data show 456,700 visitors in fiscal 2024 and 474,700 in fiscal 2025, numbers that help explain why the access point has become a choke point. Arizona State Parks said it has worked with the Arizona Department of Transportation for years to ease congestion on the approach to Oak Creek Canyon, but the new rule draws a harder line: no more waiting in line on 89A when the lot is full.

Other limits already shape the visit. Drop-offs, walk-ins and bicycles are not allowed at Slide Rock at any time. Pets are barred from May 1 through Sept. 30, and they are not allowed in the creek area year-round. The park also says its Slide Rock Market stays open year-round with seasonal hours and basic supplies such as ice, snacks, water and sunscreen, useful for anyone trying to salvage a day when parking is tight.

The park’s popularity is no accident. Slide Rock is a 43-acre historic apple farm in Oak Creek Canyon, originally the Pendley Homestead. Frank L. Pendley arrived in the canyon in 1907, acquired the land in 1910, and apple planting began in 1912. Opened and dedicated in October 1987, the site centers on an 80-foot sandstone chute and a half-mile stretch of Oak Creek for swimming, wading and sliding. With peak summer crowds approaching, the parking lot is now the first obstacle, not the last.
