Oro Valley's Holiday Season Hinges on One December Weekend

"One of Southern Arizona's largest holiday celebrations returns with live performances, artisan shopping, family art experiences, community activations, holiday music, seasonal food experiences, and the lighting of Oro Valley's signature holiday tree." That is how the Oro Valley Marketplace describes the Oro Valley Holiday Festival of the Arts & Tree Lighting Celebration, set for Saturday and Sunday, December 5 and 6, 2026.

The festival is free. Saturday runs from 10 a.m. to 6:15 p.m., and Sunday runs from 10 a.m. to 4 p.m. On the same Saturday, Tohono Chul opens Holiday Nights to the general public at 6 p.m. That leaves fifteen minutes of overlap between the season's two biggest events. Around them, the calendar fills with a midday garden event, a volunteer morning in Catalina State Park, a members' preview and a second cluster of events one week later. Oro Valley's 2026 holiday season is easiest to plan from December 5 outward.

November Builds Toward December 5

Most of November takes place outdoors and in daylight, at Catalina State Park and Tohono Chul. These dates are already posted:

• Fridays and Saturdays through November 28, 5 to 8 p.m.: Jazz Under the Stars at Tohono Chul's Garden Bistro, 7366 North Paseo del Norte. Admission is $5 for the public and free for members. Blue Dream Trio opens the November lineup on the 6th, and Blue Skies Trio closes it on the 28th.
• Saturday, November 7, 3 p.m.: The Marana Big PHAT Band plays music from the '60s through the '80s, arranged for a 20-piece big band. The show is at the Trailhead Stage during Catalina State Park's Music in the Mountains series. The park says to bring a chair.
• Sunday, November 8: Barrio Bread sells fresh loaves from 9 to 11 a.m. at Tohono Chul's Children's Ramada. That afternoon from 4 to 7, Tohono Chul and Tucson City of Gastronomy present Terruño: Flavors of the Desert, a 21-and-over evening at $150 per person. Earlier that morning at 7:15, the Everyone Runs Veterans Day trail race starts from Catalina State Park's main trailhead lot. It offers 10.6-mile, 5.3-mile and 5K distances with Aravaipa Running, and registration is required.
• Saturday, November 14, 5 to 8 p.m.: Oro Valley Parks and Recreation hosts Bark in the Park at Steam Pump Ranch, 10901 N. Oracle Road. It is free, with food trucks, vendors and a dog costume contest.
• Saturday, November 21: Ben Tully plays the Catalina Trailhead Stage at 3 p.m. From 6 to 8 p.m., The Game Plan screens at Naranja Park, 810 Naranja Drive, as part of the Town's Movies in the Park.

Two things about these dates matter in December. Jazz Under the Stars ends November 28, the Saturday after Thanksgiving, so Tohono Chul goes about a week without a regular evening program before Holiday Nights begins. Music in the Mountains also ends with Ben Tully on November 21, which leaves the Catalina Trailhead Stage without a scheduled concert for the rest of the year.

Anyone driving into Catalina State Park this season should know about a construction project. Arizona State Parks scheduled work on a wash crossing to begin the week of October 19, 2026, with completion expected in May 2027. Construction vehicles, noise and workers will be on the main road into the park, though park activities are not affected.

Thanksgiving at El Conquistador

Thanksgiving falls on November 26, the last major date before December. El Conquistador Tucson, A Hilton Resort, is serving a Thanksgiving Brunch from 10 a.m. to 2 p.m. The menu includes carved turkey, prime rib, bacon-wrapped pork tenderloin, made-to-order omelets, chilled seafood, a hot buffet and desserts. The resort's flyer lists $98 per adult and $34 for ages 6 to 12, with tax and gratuity added; children 5 and under eat free. Reservations are taken by phone at (520) 544-1255, and payment is due at booking.

The flyer gives no reservation cutoff. Because payment is collected when you book, calling early is the safer course for a party of any size.

Three Calendars Meet on December 4 Through 6

December's first weekend is the busiest stretch of the season. Holiday Nights opens with a Members' Night on Friday, December 4, then opens to the public the next evening, during the festival's longer day. Two smaller events, one at Tohono Chul and one at Catalina State Park, also fall on Saturday.

The festival's organizer, Art State Arizona, was formerly the Southern Arizona Arts & Cultural Alliance. It began in 1997 as the Greater Oro Valley Arts Council and now works statewide. Its listing says the event "brings together thousands of residents and visitors each year."

The 2026 listing does not give a tree-lighting time. The Town's 2025 announcement listed a 6 p.m. lighting for last year's festival, but that time applied to 2025 only. Before choosing between the tree and a Tohono Chul entry time on Saturday night, check the Marketplace listing again in late November.

How Saturday, December 5 Fits Together

Buffel Slayers ends at noon in Catalina State Park, and Arboretum on Tap starts at noon at Tohono Chul, so one person can't do both. Each fits naturally with the festival. One option is a park morning followed by an afternoon at the Marketplace. The other is the Marketplace in the morning, then the Adaptive Arboretum from noon to 3, which is free with garden admission.

The festival stays open until 6:15, and Holiday Nights runs from 6 to 9. Tohono Chul describes three weekends of holiday lights in the gardens, with live music, festive food and drink, holiday shopping and Santa visits. If you stay at the Marketplace until the festival closes, you'll miss the start of Holiday Nights, but the later part of the evening will still be open to you.

Two newer businesses make easy stops on the way. Tucson Foodie reported in mid-March 2026 that Bloom Tea was open at 12115 N. Oracle Road, Suite 145, serving loose-leaf tea, matcha, tea lattes and pastries. On the La Cañada side of Town, Desert Drifter Coffee opened April 24 at 10335 N. La Cañada Drive, as KGUN 9 reported.

The Second Weekend Takes Some of the Pressure Off

If December 5 doesn't fit your plans, most of the season repeats a week later with smaller crowds. Holiday Nights also runs December 11 through 13 and 18 through 20, from 6 to 9 p.m. Several events cluster around those dates:

1. Friday, December 11, 6 to 8 p.m.: Star Party at Catalina State Park's Ringtail Group Area. The Tucson Amateur Astronomy Association brings the telescopes, and admission is free with the park entrance fee. The same morning, Nature Journaling meets at 8:30 at the Trailhead Picnic Area.
2. Saturday, December 12, 9 a.m. to 1 p.m.: At Steam Pump Ranch, Second Saturdays has holiday crafts all morning and live music from Lost in Eden from 10:30 to noon. During the same hours, Heirloom Farmers Markets holds Holidays at the Markets at the Oro Valley Farmers Market on the ranch grounds, with holiday shopping, music and a free raffle.
3. Sunday, December 13: Barrio Bread returns to Tohono Chul for its December pop-up.
4. Saturday, December 19, 9 a.m. to 1 p.m.: Holidays at the Markets returns to Steam Pump Ranch, the day after Holiday Nights begins its final weekend.

The Steam Pump Ranch market runs every Saturday, and its winter hours of 9 a.m. to 1 p.m. began October 3. The December 12 and 19 holiday editions are special versions of the regular market. Catalina State Park also keeps up its regular programs through December. Guided bird walks run Sundays and Wednesdays at 8:30 a.m., plus Mondays December 7 and 21. Catalina Nights, a guided one-mile walk on the Nature Trail, meets December 4 and 18 at 5:45 p.m. and is capped at 20 people with registration required. Catalina Nights on December 4 conflicts with Tohono Chul's Members' Night, so members will have to pick one.

When you are deciding where to spend a December, the season's calendar matters too, especially if you are thinking about a second home here for the winter months.
