Tucson's hiking season has started, and this year access depends on the calendar. On Mount Lemmon, the Marshall Gulch trails are open only Friday through Sunday and on federal holidays. Kinney Road on the west side is closed until late November. Several roads in Saguaro National Park's Tucson Mountain District are closed with no reopening date at all. Meanwhile, Sabino Canyon added shuttle capacity on its busiest trail approach.
Before choosing a trail, figure out which day you're going. The same plan that works on a Saturday hits a locked gate on a Tuesday.
Mount Lemmon's top trails keep weekend hours until mid-December
Construction at Marshall Gulch has split the week in two. Starting July 27, the Arizona Trail, Marshall Gulch Trail #3, Aspen Trail #93 and Sunset Trail #90 reopened to hikers on Fridays, Saturdays, Sundays and all federal holidays. Monday through Thursday, the whole area is closed for public safety while crews work. The Coronado National Forest alert, last updated August 1, confirms that schedule and runs through December 17, 2026. The Arizona Trail Association's update says trailhead parking stays closed until December 15, 2026. On weekdays, the association points Arizona Trail users to the Mint Spring Trail instead.
The federal-holiday exception adds a few weekdays to the open list. The rest of this fall's holidays fall on weekdays: Columbus Day on Monday, October 12; Veterans Day on Wednesday, November 11; and Thanksgiving on Thursday, November 26. Under the posted rule, the trails should be open on all three.
Parking moved rather than disappeared. A finished Pima County project in Summerhaven added a paved 75-space lot and 21 roadside spaces along Sabino Canyon Park Road, resurfaced about half a mile of road, and built a five-foot Arizona Trail bypass path near Marshall Gulch. With the trailhead lot closed, the Arizona Trail Association names the Summerhaven lot as the place to park.
Weekdays point to Catalina State Park and Saguaro's east side
When the Marshall Gulch area is closed, two nearby options stay fully open on the same days.
Catalina State Park has scheduled its fall programs around weekdays as much as weekends. A Native Plant Walk on Thursday, October 15, runs from 7:30 to 10:30 a.m. and heads down into Romero Canyon. Guided bird walks start Sunday, October 18, and continue on Sundays, Wednesdays and select Mondays through May 17, 2027.
Saguaro National Park's Rincon Mountain District, the east side, has no closures. The park's current conditions page lists every road, picnic area and trail there as open. Through May 31, the Rincon Mountain Visitor Center is open daily from 9 a.m. to 5 p.m., with water on the patio and at the bike ramada.
Here is how the week looks across the three areas most affected this fall:
| Day | Marshall Gulch area, Mount Lemmon | Saguaro, Rincon Mountain District | Saguaro, Tucson Mountain District |
|---|---|---|---|
| Monday to Thursday | Closed for construction, except federal holidays | All roads and trails open | Bajada Loop Drive, Hohokam Road and Golden Gate Road closed |
| Friday to Sunday | Trails open to hikers; trailhead parking closed | All roads and trails open | Same closures apply |
| Federal holidays | Trails open to hikers | All roads and trails open | Same closures apply |
The west side has one closure with an end date and one without
The Tucson Mountain District has two separate closures, and only one of them has an end date.
The one with a date is Kinney Road. Per a National Park Service alert posted September 11, Kinney Road is closed from the eastern intersection of McCain Loop to the Arizona-Sonora Desert Museum from October 1 through November 24, and McCain Loop is the posted detour. Anyone heading to the Desert Museum through the end of November should plan on the McCain Loop route. The alert does not give a reason for the closure.
The one without a date is inside the park. The same alert closes Bajada Loop Drive, including all of Hohokam Road and Golden Gate Road, because of road damage from September storms. It will reopen only after the road is repaired, the area is declared safe and the signs come down. That also affects a route some cyclists and hikers use regularly. Golden Gate Road between the Sendero Esperanza trailhead and Picture Rocks Road is normally closed to cars and serves as a multi-use trail for hikers, cyclists and riders on horseback. The alert covers all of Golden Gate Road. Check the conditions page before planning a ride on that stretch.
The Red Hills Visitor Center stays on its usual season hours, open daily from 9 a.m. to 5 p.m. through May 31.
Sabino Canyon added capacity on the Seven Falls approach
At the base of the Catalinas, the change makes access easier. The Sabino Canyon Crawler now runs 23-passenger electric shuttles on the 1.9-mile Bear Canyon route to Bear Canyon Overlook and the Seven Falls trailhead, according to the Pima Association of Governments. The new shuttles supplement the larger Sabino Canyon shuttle and may also run the main Sabino route during slower months.
The operator's FAQ lists fares of $15 for adults and $8 for children on the Sabino Canyon tram, and $8 for adults and $5 for children on the Bear Canyon shuttle. Children under three ride free with a guardian. Saturday night tours run through October 31, with departure times posted online. The operator's daytime schedule is not confirmed in any recent source, so check its site for current departure times before planning around the last shuttle back.
Tumamoc Hill keeps its usual rules. The University of Arizona's Desert Laboratory page allows walking on the paved road daily from 4 a.m. to 10 p.m. and does not allow bicycles on the hill.
The fall calendar, matched to the access schedule
Several of this fall's organized outings fit around the closures. The Sabino Canyon Naturalists' free hike on Friday, October 16, covers the Sunset and Aspen trails. That is about 4 miles with 500 feet of climbing, meeting at 7:45 a.m. at the Sunset Trailhead near Catalina Highway milepost 22.9. Both trails are inside the Marshall Gulch area that opens on Fridays, so the hike falls on one of the days the area is open.
| Date | Event | Where | How it fits the access schedule |
|---|---|---|---|
| Saturday, Oct. 10 | Wildlife Extravaganza, free | Historic Boathouse at the base of Tumamoc Hill | Visit Tucson's listing points visitors to street or dirt-lot parking, not parking on the hill |
| Saturday, Oct. 10 | Star Party with the Tucson Amateur Astronomy Association | Catalina State Park | Start time varies by date; check the park listing |
| Thursday, Oct. 15 | Native Plant Walk, 7:30 to 10:30 a.m. | Catalina State Park, into Romero Canyon | A weekday outing while Marshall Gulch is closed |
| Friday, Oct. 16 | Sabino Canyon Naturalists' Sunset and Aspen hike | Sunset Trailhead, Catalina Highway milepost 22.9 | Falls on an open day for the Marshall Gulch area |
| Sunday, Oct. 18 | Guided bird walks begin | Catalina State Park | Continue Sundays, Wednesdays and select Mondays through May 17, 2027 |
| Sunday, Nov. 8 | Veterans Day trail race, 7:15 a.m. | Catalina State Park | Distances of 10.6 miles, 5.3 miles and 5K, run with Aravaipa Running |
| Saturday, Nov. 21 | 43rd El Tour de Tucson | Citywide | The organizer says the event usually draws more than 11,000 cyclists |
| Tuesday, Nov. 24 | Scheduled end of the Kinney Road closure | Between McCain Loop and the Desert Museum | Bajada Loop Drive has no posted reopening date |
The race details are on the Catalina State Park event page, and the ride date is posted by El Tour de Tucson.
The trail race on November 8 and El Tour on November 21 are fixed events. The Marshall Gulch weekday closure through mid-December, the Kinney Road reopening on November 24 and the Bajada Loop repairs all depend on construction and road work, so the Forest Service alert and the Saguaro conditions page are worth checking the morning you go. On the Chuck Huckelberry Loop, AZ Luminaria reported in June that Pima County is working on a Loop Improvement Plan, with a framework expected before the end of 2026.
Part of everyday life in Tucson is how close a home is to the trailheads you actually use, whether that's Catalina State Park, the Rincon side of Saguaro or the road up Mount Lemmon. If that's part of your thinking about where to live next, Michael Fleming is glad to talk through how different parts of Tucson line up with the places you get outside. Let's Connect.
