What is Skyline Regional Park?
The White Tank Mountains run south almost to I-10, and the last 8,700 acres of them belong not to the county but to the City of Buckeye, which opened Skyline Regional Park in January 2016 with seven miles of trail and has been adding to it since. There are now more than 20 miles of purpose-built hiking, mountain-biking and equestrian trail climbing from a trailhead at about 1,500 feet into the rocky southern end of the range, with ramadas, flush restrooms, a horse staging area and a short loop of seven primitive campsites. In 2026 the Bureau of Land Management approved a 25-year lease that adds about 640 acres of federal land to the park.
It is the plain, well-built, uncrowded cousin of the county parks. No nature center, no petroglyph plaza, no gate fee. The trails are newer and better graded than the old canyon routes at White Tank Mountain Regional Park ten miles north, which is why West Valley mountain bikers have adopted it, and because Buckeye is far from almost everyone, you can ride on a January Saturday and meet a dozen people. The campsites, A through G, each have a table and a fire ring on a level pad, flush restrooms a short walk away, no hookups, no drinking water and a view east over Buckeye’s lights to the Estrellas. Campers report about $20 a night, booked through the city at least 72 hours ahead, with a seven-night maximum.
What you get is the only free mountain park on the west side of the Valley, with the best-graded bike trails in the White Tanks and the cheapest legal campsite within an hour of Scottsdale. What you do not get is water for people, a landmark, a campground away from the trailhead, or a reservation system you can trust without a screenshot.
How to do Skyline right
Pay nothing to visit, book early to camp. No entry fee. Camping is about $20 a night through the city’s online portal, which is run by a third-party vendor, requires an account and 72 hours’ notice, and does not always behave; it has been known to double-book, so screenshot your confirmation and arrive before dark to claim your pad. Confirm with Buckeye Parks and Recreation if anything looks wrong. Walk-ups are sometimes accommodated for one night and cannot be counted on.
Get there. Loop 101 south to I-10 west, about 35 miles across the Valley past the Loop 303 to Watson Road (exit 117), then north two miles to the park entrance on the left. Figure 55 minutes from Old Town with no traffic, and avoid westbound I-10 at the evening rush. Everything is paved. The trailhead lot is large and rarely full; the campground loop is just beyond it, close enough that early hikers will walk past your tent.
Pick the season. October through April. Trails are open sunrise to sunset year round and the gate closes at 10 p.m.; in summer the park is a first-light-only place, like every low-desert trail in the Valley, and the summer rules apply.
Water. None for people. Flush restrooms at the trailhead, a trough for horses. Bring every drop for the day and the night. There is no trash service at the sites, so pack it out.
Pick a site and a trail. Sites A through G are spread out and level, which matters more than any amenity here, and the view east over Buckeye at night is a long way from the Valley’s glow. The trails nearest the trailhead get the dawn traffic from Verrado; walk or ride 20 minutes in and you will have the mountain. The four-mile Turnbuckle Loop is the standard first visit; Skyline Crest climbs to the park’s high point at 3,152 feet.
Fire. Fire bans are not posted online, so call the city before you count on a campfire.
Horses. Welcome, with a staging area and water trough at the trailhead, and several trails built with riders in mind.
Dogs. On leash on all trails and at the campsites.
Skip it if you want hookups, showers or a destination. The county’s White Tank campground is 20 minutes north with both, and Estrella Mountain Regional Park and its campground are the other west-side option. For a free trail system and a $20 night under a dark sky, this is the best deal on the west side.
The suburb that leased itself a mountain range
The White Tanks are named for what the rain does to them: storms rushing down the steep canyons scour depressions, tanks, into the white granite at the range’s base, and the tanks held water in a dry country. Hohokam farmers of the Gila and the Agua Fria hunted and gathered in the range and left petroglyphs in its canyons, which is most of what the county park to the north interprets; the range itself is young, a block of metamorphic rock lifted along a detachment fault about 30 million years ago and topped by Barry Goldwater Peak at 4,083 feet.
Buckeye began as a canal. Malie Jackson, an Ohioan, dug ten miles of ditch off the Gila between 1884 and 1886, and in 1888 laid out a town he called Sidney after his hometown; everyone called it Buckeye after the canal, and the name became legal in 1910. The town incorporated in 1929 on 440 acres and stayed a farm town for most of a century, with the White Tanks to its north left as federal range for cattle and the occasional prospector while Maricopa County built its regional park on the range’s northern end.
Then Buckeye became the fastest-growing city of its size in the country. Between 2010 and 2020 its population rose from 50,876 to 91,502, about 80 percent, as master-planned communities, Verrado foremost, climbed the southern foothills of the White Tanks, and the city annexed its way to 393 square miles, the second-largest city by area in Arizona. The land above the subdivisions was still federal. Rather than wait for the county, the city went to the Bureau of Land Management and leased it: about 8,700 acres of the southern White Tanks on a 25-year recreation lease, after which the park reverts to the city.
Skyline Regional Park opened in January 2016 with seven miles of trail, ramadas, flush restrooms and a horse staging area, built new rather than inherited, which is why the grades suit mountain bikes. The network grew past 20 miles, with the Turnbuckle Loop as its signature, the Skyline Crest trail to the park’s 3,152-foot high point, Javelina summit looking back to downtown Phoenix, and, in 2018, 0.6 miles of accessible trail with interpretive panels. The city added monthly guided hikes and star parties under skies that are, for the Valley, dark. The seven-site campground came in beside the trailhead, dry, cheap and booked through a vendor’s portal. In 2026 the BLM approved a new 25-year lease adding about 640 acres.
What is coming is Buckeye. The city expects to keep growing toward the park on every side that is not mountain, and the lease arrangement means the park’s future depends on the BLM and the city agreeing every quarter century.
Why it matters
Skyline is what a boom suburb did instead of waiting for the county: it leased a mountain range from the federal government and built a park from scratch, free, with trails designed for the people who actually use the West Valley’s desert, mountain bikers and horse riders and families from Verrado. It explains how the fastest-growing part of the Valley thinks about open space, as infrastructure to build now rather than land to protect later, and it is the only free mountain park on the west side. For a Scottsdale visitor the verdict is practical. It is nearly an hour away and has no landmark, and the campground is small and next to the trailhead; but for a free trail system, a 20-minute walk to an empty mountain and a $20 night under a dark sky, nothing else in the Valley competes. Book three days ahead, screenshot it, and bring every drop of water.
