Troon's Fall Trail Season Runs on a Sign-Up Calendar

In late October, a walk out to Pinnacle Peak starts to call for a calendar reminder. Three changes land within about two weeks of each other. The park closes earlier, Brown's Ranch Trailhead is expected back after a summer rebuild, and the registration windows open for the park's most popular winter programs.

The daylight math explains why. Pinnacle Peak Park's posted annual schedule keeps the gates open from 5 a.m. to 8 p.m. between June 15 and July 14. That's 15 hours. From Oct. 15 the window is 6:15 a.m. to 6 p.m., and from Dec. 1 it is 7 a.m. to 5:30 p.m., or 10.5 hours. The park loses four and a half hours a day between midsummer and December. Most of that loss comes in the evening, which is when the desert is at its best this time of year.

The After-Hours Programs That Need a Sign-Up

Several of the park's fall events run past the posted closing time, and most of them need advance registration.

The clearest case is Astronomy Evenings. On Friday, Oct. 30, the session starts at 6:15 p.m., fifteen minutes after the gates would normally close. More sessions follow on Friday, Nov. 13 and Friday, Dec. 4, both at 6 p.m. The host is Mark Johnston, a NASA Solar System Ambassador. He walks the group through the planets, multiple star systems, globular clusters and nebulae visible that night through a high-end refractor telescope, and takes questions as he goes. The city suggests bringing a folding chair, binoculars and a small penlight. Registration opens 30 days before each date. Sessions are canceled for rain or overcast skies, and the Visitor Center at 480-312-0990 asks attendees to call that afternoon to confirm.

The Sunset–Full Moon Hikes work the same way, except that no registration is required. Each is a moderate 1.5-mile round trip to the Grandview Overlook, with staff and volunteers on the trail. The remaining fall dates are:

• Sunday, Oct. 25, 4:30 to 6:15 p.m.
• Tuesday, Nov. 24, 4:30 to 6 p.m.
• Wednesday, Dec. 23, 4:15 to 6:15 p.m.

On Nov. 24 the park's posted closing time is 5:30 p.m. On Dec. 23 it is also 5:30 p.m., but the hike runs until 6:15. Without a sign-up, these hikes are the main way a resident can be on the Pinnacle Peak trail after dark in late fall. The city asks hikers to arrive no later than the start time, and these hikes are also canceled for rain or overcast conditions.

The 30-Day Rule

Most of the registered programs at Pinnacle Peak Park share one rule: sign-ups open 30 days before the event. That means the calendar to watch is the registration dates, not the event dates. Counting back from the city's listings gives this rough schedule:

The Dec. 13 Trail Tales book is The Gingerbread Cowboy, a Southwest-focused picture book followed by a craft. The Geology Adventure, a guided 3/4-mile hike to the Grandview Overlook with a park geology guide, runs Saturday, Nov. 21 and Friday, Dec. 18, both at 9 a.m. It also requires registration.

The Wildlife Discovery Programs are the main exception. Local nonprofit rescue and education groups bring live animals to the Ramada from 10 a.m. to noon. The city calls them free for all ages and lists no registration step. Arizona Bat Rescue is scheduled for Nov. 14, the Phoenix Zoo for Nov. 21 and Wild at Heart for Dec. 19.

Oct. 24 Is the Busiest Date

On Saturday, Oct. 24, two separate deadlines fall within an hour of each other:

1. 8 a.m. Registration opens for the Jingle Hike to Santa on Saturday, Dec. 5. The hike is free and runs at 9 and 10 a.m. Children get a bell to jingle on the self-guided climb to meet Santa at the Grandview Overlook, followed by hot cocoa, treats, crafts and face painting. The city says space is limited and enrollment is required.
2. 9 to 11 a.m. Eek! At the Peak! takes over the park, with registration through ActiveNet. The city's preserve page lists costume contests, a scavenger hunt, Arizona Bat Rescue, nature stations, book giveaways and a DIY craft.

For the Jingle Hike, the city recommends closed-toe shoes and water. It also asks families to leave enough time to reach the overlook, since the hike is self-guided.

Brown's Ranch Is Expected Back Later This Month

Pinnacle Peak is only part of the picture. Brown's Ranch Trailhead at 30301 N. Alma School Pkwy is closed for an improvement project that the city listed with an expected start date of July 13. The project page puts the budget at $1,165,599, paid from the 2004 Preservation Sales Tax. October is Preserve Month in Scottsdale, and the city's McDowell Sonoran Preserve page, updated at the end of September, still lists the trailhead as closed. Its list of Preserve Month activities includes this line:

Watch for the grand reopening date of Brown's Ranch Trailhead anticipated for late October.

So far, "anticipated" is as firm as the city has gotten. No reopening day had been posted as of that update. The project page still gives only "Fall 2026" for completion.

When it reopens, the trailhead won't look the way it did in spring. The project page lists three changes. The parking lot has been redesigned for durability, drainage and circulation. The trailhead buildings are getting new lighting and roofing. And a new trail dispersal area reroutes five trail segments to ease congestion while protecting sensitive areas. The city hasn't published names for the rerouted segments, so regulars should expect their usual first mile to change.

Until the reopening, the closure rules still apply. Parking isn't allowed on nearby streets or in neighborhoods around the trailhead. The city points hikers to four alternatives: Tom's Thumb, Pima-Dynamite, Fraesfield and Granite Mountain. Tom's Thumb, Fraesfield and Granite Mountain have no drinking water, so bring your own.

Preserve Month brings a few extras through October. Exploration Journals for children up to third grade are available at any trailhead, along with a commemorative sticker. The McDowell Sonoran Conservancy is running guided hikes, rides and education programs all month, and its events calendar has sign-ups.

The Drive There Is Changing Too

For anyone driving to the trailheads west of Troon, the Scottsdale Road project between Jomax Road and Dixileta Drive is still underway, including a redesigned Dynamite Boulevard intersection. The city says lane reductions and turn restrictions are possible during the work. It plans to keep at least one travel lane open in each direction and is targeting completion in late 2026. The city's schedule for Pima Road between Happy Valley Road and Jomax Road shows construction starting in winter 2026 and finishing in summer 2027. That schedule was last updated in January, so treat it as a plan rather than confirmed timing.

Lunch After the Hike

The earlier closing times also change when hikers come off the trail. A morning hike now ends closer to lunch, and there's a new option nearby. Baan Thai opened at 7605 E. Pinnacle Peak Road, on the southeast corner of Miller and Pinnacle Peak, and PHOENIX magazine included it in its September openings roundup. Mouth by Southwest reported a menu that goes beyond the usual pad Thai. It has crispy pork shoulder with smoky jaew dipping sauce for $16, a Nam Tok Ribeye salad with toasted rice powder for $22, and a golden-fried whole pompano with tamarind or ginger sauce for $25.

Weekday timing matters here. Baan Thai serves from 11 a.m. to 3 p.m. and 4 to 9 p.m. Monday through Friday, so it's closed for an hour mid-afternoon. On Saturdays it's open straight through from 11 a.m. to 9 p.m., and on Sundays from noon to 9 p.m. A Saturday Wildlife Discovery morning that ends at noon leaves plenty of time for lunch.
