San Tan Mountain Regional Park: Every Trail, Fee and Rule, Checked Against the County’s Own Pages

San Tan Mountain Regional Park is more than 10,000 acres of Sonoran Desert on Queen Creek’s southern edge, at 6533 W. Phillips Road. The land sits in Pinal County, and Maricopa County Parks and Recreation operates it. Entry is $10 per vehicle, the standard Maricopa County parks rate effective January 1, 2026. The gate is open 5 a.m. to 9 p.m. from May 1 through October 31 and 6 a.m. to 8 p.m. from November 1 through April 30. Its nine named trails add up to 20.1 miles by our sum of the county’s own rows, and every one of them is open to hikers, cyclists and horses.

That split is not a technicality — it dates to a 1986 agreement among the two counties and the Bureau of Land Management, and it decides whose fees and whose rules you are under. The hours, fees, trail rows and rules below come from the county’s own pages as of September 20, 2026, including the fee rises already approved for 2027 and 2028; where the Town of Queen Creek, the National Weather Service or the Postal Service is the source instead, the page says so. One line on the county’s page we print only with a warning attached: the ZIP code. It is the largest open space in our guide to things to do in Queen Creek.

The Honest San Tan Verdict

Twenty miles of multi-use desert trail for $10 a carload, immediately south of Queen Creek, run by a county that publishes its fees, its rules and its trail mileage in full. What it does not publish — a drive time, equestrian staging, any heat-closure policy — is why the tables below exist.
Who it fits: Anyone who wants real desert mileage and elevation without crossing the valley; households that will visit parks in the Maricopa County system a dozen or more times a year and can amortize the $120 annual pass; and riders and cyclists who want trails that are legally open to them rather than merely tolerated.
Who should choose elsewhere: Anyone who does not want to pay a gate fee for a walk, or who needs a short, near-flat loop — only two of the nine trails are rated Easy and the shortest is 0.7 miles. Anyone hauling a horse trailer should call first: the county publishes no staging-area or trailer-parking detail at all.
The one catch: The hours are seasonal, and the Town of Queen Creek’s own parks page publishes a different set. Maricopa County operates the gate, so the county’s page is the one to plan around: 6 a.m. to 8 p.m. from November 1 through April 30. A January sunset loop planned around a 9 p.m. closing ends at a locked gate.

1.The Basics, and the Hours Three Sources Disagree On

Maricopa County Parks and Recreation runs the park and calls it more than 10,000 acres of Sonoran Desert, from about 1,400 feet to over 2,500 feet. The Town of Queen Creek’s About page puts it at 10,200 acres; both are official, so we quote the operator and flag the other. The line the operator publishes is (602) 506-2930 ext. 7; the (480) 655-5554 on the Town’s parks page is the Town’s own number, not the park’s.

Gate and Nature Center hours, Maricopa County Parks (September 2026)
SeasonPark gate hoursNature Center hours
May 1 – Oct 315:00 a.m. – 9:00 p.m. daily7:00 a.m. – 2:00 p.m. Mon–Sat, closed Sunday
Nov 1 – Apr 306:00 a.m. – 8:00 p.m. daily8:00 a.m. – 4:00 p.m. daily
Heads up

Two official pages disagree. The Town of Queen Creek’s parks page lists 6 a.m.–8 p.m. Sunday to Thursday and 6 a.m.–10 p.m. Friday and Saturday, and a map listing checked in an earlier research pass, and not re-checked for this page, showed a flat 5 a.m.–9 p.m. year-round. Maricopa County operates the gate, so the table above is the schedule to plan around.

2.Why a Maricopa County Park Sits in Pinal County

A 1986 agreement among Maricopa County, Pinal County and the federal Bureau of Land Management created the park; the core was federal land, and Maricopa County has added acreage since. The ground is entirely inside Pinal County, the operation entirely Maricopa County’s — the same puzzle as which county Queen Creek is in, in a harder form.

  • You pay Maricopa County’s fee schedule while standing in Pinal County.
  • Maricopa County park rules apply — the leash length, trail-use rules and fire ban below are all theirs.
  • A Maricopa County annual pass works here, because San Tan is one of that system’s parks.

One warning before you type the address anywhere. The county publishes it as 6533 W. Phillips Road, Queen Creek, AZ 85144, and that ZIP is contested: the Postal Service’s own recommended city for 85144 is San Tan Valley, with Queen Creek only an accepted alternate, and an independent geocode of the same street returns 85142 instead. The coordinates are the solid part — (33.16802, -111.63538), matching the county’s own map link to four decimals. Use the street address and the coordinates, and read how the local ZIP codes actually work before reading anything into the number.

The human history runs far deeper than the 1986 paperwork. The Hohokam farmed this ground from roughly A.D. 1100 to 1450, and the evidence is still on the surface in the form of rockpile agricultural fields — roughly 350 years of cultivation on land that had no Queen Creek, no county line and no gate fee.

3.Every Named Trail, by Length and by Elevation Change

The county publishes a mileage, an elevation-change figure and a difficulty rating for each of its nine named trails. Here they are sorted shortest to longest, with a column it does not provide — feet of elevation change per mile, our arithmetic on its own two figures. All nine are multiple-use: hikers, bikes and horses share every tread.

All nine trails, Maricopa County Parks (September 2026). The last column is our arithmetic.
Trail (code)LengthElevation changeCounty ratingChange per mile
Littleaf (LL)0.7 mi85 ftEasy121 ft
Stargazer (SG)0.8 mi88 ftEasy110 ft
Rock Peak Wash (RP-W)0.9 mi93 ftModerate103 ft
Hedgehog (HG)1.0 mi126 ftModerate126 ft
Moonlight (ML)1.3 mi131 ftModerate101 ft
Dynamite (DN)2.4 mi288 ftModerate120 ft
Goldmine (GM)2.5 mi541 ftDifficult216 ft
Malpais (MP)4.1 mi202 ftModerate-Difficult49 ft
San Tan (SA)6.4 mi234 ftModerate-Difficult37 ft

Read the last two columns together and the park sorts itself. Goldmine is the outlier — 541 feet inside 2.5 miles, or 216 feet of change per mile against 126 for the next steepest, and the only trail the county rates Difficult. Malpais and San Tan carry Moderate-Difficult on gentle grades, which leaves length as the plain reading: San Tan averages the gentlest 37 feet per mile and is still the longest walk in the park at 6.4 miles. Rock Peak Wash is rated Moderate at 0.9 miles, so short does not mean beginner here.

Goldmine is named literally. Prospectors Mansel Carter and Marion Kennedy mined gold, silver and turquoise here in the 1940s, and historic sites and graves remain near Goldmine Mountain; the same name sits north of the line at Mansel Carter Oasis Park. For desert walking closer in, the in-town option is the Queen Creek Wash trail system.

4.Entry Fees, the Pass Math and the 2027–2028 Increases

The Board of Supervisors approved this schedule on December 10, 2025, effective January 1, 2026, with rises already written in for 2027 and 2028. The $10 vehicle fee is the county’s standard rate for all its parks except the conservation areas and the Desert Outdoor Center.

Maricopa County Parks fees at San Tan — approved Dec. 10, 2025, effective Jan. 1, 2026
FeeRate nowIncrease already approved
Vehicle entry, day use$10.00$12.00 on Jan. 1, 2028
Hike, bike or equestrian entry$5.00None published
Annual day-use pass, all county parks$120.00$140 in 2027, $160 in 2028
School bus$15.00None published
Developed campsite, per night$40.00$50 in 2027, $60 in 2028
Semi-developed campsite, per night$25.00None published
Shaded RV site, per night$65.00None published
Reservation fee, non-refundable$10.00None published

At current rates the $120 annual pass breaks even on the twelfth vehicle entry — $120 divided by $10, our arithmetic — and those entries can be spread across any park in the Maricopa County system. The break-even only moves out from there: on the 2027 schedule ($140 pass, $10 entry) it takes fourteen visits, and on the 2028 schedule ($160 pass, $12 entry) fourteen again. Once-a-season visitors should keep paying at the gate.

Heads up

Two things the schedule does not settle. It publishes the $10 reservation fee as non-refundable but does not say whether it is charged once per stay or once per night, which matters most on a $25 semi-developed site. And it does not say whether the $5 hike, bike and equestrian entry is charged per person or per party. Call (602) 506-2930 ext. 7 before booking a multi-night site or planning a group around the walk-in rate.

5.Dogs, Bikes and Horses: the Rules the County Publishes

Maricopa County Parks rules at San Tan — adopted Aug. 13, 2003, revised Jan. 13, 2016
ActivityWhat the rule says
DogsLeash six feet or shorter, a current dog license, clean up; no dogs in park buildings except service animals
Horses and livestockDesignated trails and areas only, or under a special permit
BicyclesDesignated trails only, no reckless riding; ramps prohibited outside designated areas
Leaving the trailProhibited between trailheads; stay on trails designated for your use
CampingA written Department permit, plus the posted camping regulations
FiresDesignated places only; wood and charcoal banned in a posted fire ban, gas and propane in an extreme ban
Quiet hoursNo disturbing generators, motors or radios, 10 p.m. to 6 a.m.
Groups and commercial useA Special Use Permit for commercial or organized group activity outside the park’s normal design

Two of those trip people up. The dog rule is not only a leash rule — it requires a current dog license, which nobody thinks about on the way to a trailhead. And the stay-on-trail rule names the ground between trailheads, so stepping off the tread for a photograph is what it covers.

For horses the county publishes the rule but not the logistics: no staging area or trailer-parking detail appears on any San Tan page as of September 2026. Call before you haul. Two Town sites do publish equestrian facilities: Horseshoe Park & Equestrian Centre, a 38-acre dedicated event venue, and Desert Mountain Park, whose amenity list includes an equestrian staging area and wash trail access.

6.Summer Hours, the Fire Ban and the Heat Policy That Is Not There

As of September 2026 Maricopa County Parks publishes no heat-based trail-closure threshold for San Tan on its park, rules or fee pages — no posted temperature at which the trails shut. The only dated seasonal restriction is the countywide fire ban; the only heat accommodation is the gate, which opens at 5 a.m. from May 1 through October 31, an hour earlier than in winter.

Gate hours and fire ban against Phoenix Sky Harbor 1991–2020 NOAA normals (Queen Creek has none of its own)
MonthPhoenix-area average highGate hoursWood or charcoal fires
May94.5°F5 a.m. – 9 p.m.Banned from May 1
June104.2°F5 a.m. – 9 p.m.Banned
July106.5°F5 a.m. – 9 p.m.Banned
August105.1°F5 a.m. – 9 p.m.Banned
September100.4°F5 a.m. – 9 p.m.Banned through Sept. 30

November – April66.2°F (Dec.) to 85.5°F (Apr.)6 a.m. – 8 p.m.Designated places only

Those normals are Phoenix Sky Harbor’s, not Queen Creek’s — the town has no published 30-year NOAA normals of its own, as our month-by-month weather guide sets out — and Sky Harbor averages 111.3 days a year at or above 100°F. Against a 6.4-mile trail in that heat the rule writes itself: from May to September you are at the gate at 5 a.m. or picking something under a mile. Our summer survival guide covers the rest.

Good to know

The National Weather Service runs Arizona’s monsoon on a fixed calendar, June 15 to September 30, rather than on the weather. It is a communication convention, not a forecast — but it is the window in which afternoon storms and flash flooding are the planning risk on a desert wash trail, and it sits inside the May 1 to September 30 fire ban and ends on the same day.

7.The Nature Center, Camping and Getting There

The Nature Center keeps its own hours. From May 1 through October 31 it opens 7 a.m. to 2 p.m. Monday through Saturday and not at all on Sunday — so a summer Saturday afternoon finds open trails and a closed building seven hours before the gate shuts, and a summer Sunday finds the building closed all day. From November 1 through April 30 it is 8 a.m. to 4 p.m. daily. Beyond the hours the county publishes almost nothing — no square footage, no exhibit list, no opening year, no dated 2026 program calendar, only a generic link into the system-wide events listing. Call (602) 506-2930 ext. 7 for what is actually scheduled on the day you want.

Camping is reservable — developed, semi-developed, shaded RV, and group and youth sites — and every stay needs a written Department permit. The fee table above carries nightly rates for the developed, semi-developed and shaded RV sites, plus the $10 reservation fee; the county publishes no rate for the group and youth sites, so ask for those on the phone. The countywide wood-and-charcoal ban covers every night from May 1 through September 30.

The county’s route from central Phoenix is I-10 east to US 60 east, south on Ellsworth Road to Hunt Highway, east to Thompson Road, south, then west on Phillips Road to the entrance. From inside Queen Creek that is the last three legs of the same route — Hunt Highway east to Thompson Road, Thompson south, then west on Phillips Road — which is our reading of the county’s own directions, not a separate route it publishes. We publish no drive time because the county publishes none, and it gives directions to one entrance only, so confirm any second trailhead by phone.

  1. Check the county page for the season you are in — the hours change on May 1 and November 1, not on a holiday weekend.
  2. Pick the trail off the table above by elevation change per mile, not by the difficulty word alone.
  3. Bring $10 for the vehicle, or buy the annual pass if this is visit number twelve.
  4. Between May and September, be at the gate when it opens at 5 a.m., and leave the wood and charcoal at home — the countywide ban covers both from May 1 through September 30, and an extreme ban adds gas and propane.

If this park is part of why you are eyeing the south side of town, the trade-offs — the drive, the county line, what is close and what is not — are the substance of our guide to living in Queen Creek.

Is San Tan Mountain Regional Park in Queen Creek or in Pinal County?

The land is in Pinal County. The park borders the Town of Queen Creek on the south rather than sitting inside it, and the county publishes a Queen Creek mailing address for the entrance. Maricopa County Parks operates the park under a 1986 agreement with Pinal County and the Bureau of Land Management, so Maricopa County’s fees and rules apply on Pinal County ground.

Which trail is the hardest at San Tan Mountain Regional Park?

Goldmine Trail: 2.5 miles with 541 feet of elevation change, the only trail the county rates Difficult and the most elevation change per mile in the park, 216 feet by our arithmetic. Malpais and San Tan are Moderate-Difficult for their length.

Are dogs, bikes and horses allowed on the trails?

All three, on every named trail. Dogs need a leash six feet or shorter and a current dog license. Bikes stay on designated trails; horses are limited to designated trails and areas unless you hold a special permit.

Can you camp at San Tan Mountain Regional Park?

Yes. Developed, semi-developed, shaded RV and group or youth sites are reservable, and every stay needs a written Department permit. Nightly rates run $25 to $65 as of 2026, plus a $10 non-refundable reservation fee.

Do the trails close when it gets too hot?

Maricopa County Parks publishes no heat-based closure threshold for San Tan on its park, rules or fee pages as of September 2026. The gate simply opens an hour earlier, at 5 a.m., from May 1 to October 31.
