Southwest winter road trip itinerary: a 10-day Arizona and New Mexico loop

Route Phoenix, AZ → Phoenix, AZ

Distance 1,850 miles

Estimated fuel $280

A 10-day winter loop from Phoenix through Saguaro, White Sands, Carlsbad Caverns, Santa Fe, Petrified Forest and the Grand Canyon, with current park fees, missile-test and mountain-road warnings, and a warm low-elevation variant.

The best Southwest winter road trip itinerary for 10 days is a loop from Phoenix. It runs east through Tucson and Saguaro, Chiricahua, White Sands and Carlsbad Caverns, then north to Santa Fe and back west along I-40 via Petrified Forest, the Grand Canyon's South Rim and Sedona. That's about 1,850 miles, with no day much over 5 hours of driving. The southern half (Tucson to Carlsbad) is reliably mild from December to February. The northern half (Santa Fe, Flagstaff, the Grand Canyon) sits at 7,000 feet, give or take, and can bring snow and ice. If you want warmth above all, use the low-elevation variant described below.

Why this loop works in winter

Most classic Southwest loops are built for spring and fall. In winter, the high plateaus of southern Utah get cold and short on daylight, which is why the Utah Mighty 5 road trip is better saved for another season. This loop keeps the first five days in the low desert and the Chihuahuan basins of southern Arizona and New Mexico, where winter is the comfortable season for hiking. It saves the high-country stops for the second half, where you can trim them if a storm moves in.

Day by day

Days 1-2: Tucson, Saguaro and Chiricahua

Saguaro National Park has two districts on opposite sides of Tucson, and one $25 vehicle pass covers both for 7 days. The park does not take cash. Do the Tucson Mountain District (west) on the afternoon of day 1. On day 2, drive the Rincon Mountain District's Cactus Forest Loop in the morning. Then head east on I-10 to Willcox and Chiricahua National Monument, known for its rock spires. Check the monument's NPS page for current road and trail status before you go.

Day 3: White Sands National Park

Take I-10 east to Las Cruces, then US 70 over San Augustin Pass to White Sands. Entry costs $25 per vehicle for 7 days, and the park takes cash or card. Plan this day around missile testing. The NPS says the park road can close for up to three hours when the neighboring White Sands Missile Range is testing, and that US 70 between Las Cruces and Alamogordo also closes during tests. Check the park closure page the day before. The park is closed on Thanksgiving and Christmas Day and can close unexpectedly in winter for unsafe roads or weather. The NPS posts closures on its Facebook page and on NMRoads, the New Mexico DOT's road-conditions site. Stay for sunset on Dunes Drive, then sleep in Alamogordo.

Days 4-5: Over the mountains to Carlsbad Caverns

US 82 east from Alamogordo climbs through Cloudcroft in the Sacramento Mountains before dropping to Artesia and Carlsbad. It is the most winter-exposed road in the southern half of the loop, so check NMRoads that morning. If it's icy, go around via US 54 and US 380, or through El Paso.

Carlsbad Caverns needs two things: a $1 timed-entry reservation on Recreation.gov, required year-round, and a $15 per-person entrance fee (age 16 and up) paid at the visitor center. An America the Beautiful pass covers the entrance fee but not the reservation. The cavern is closed on Thanksgiving, Christmas and New Year's Day. As of the park's latest fee page, all ranger-guided tours are suspended, so plan on the self-guided Natural Entrance and Big Room routes. Use the spare half day for Guadalupe Mountains National Park across the Texas line, or rest in Carlsbad.

Days 6-7: Santa Fe

Day 6 is a long transfer north through Roswell. Santa Fe is the cultural stop of the trip: adobe streets, museums, galleries and New Mexican food. At about 7,000 feet, it is also cold in winter, so pack a real coat. Bandelier National Monument is the obvious day trip if roads are clear.

Day 8: Petrified Forest National Park

Take I-25 south to Albuquerque, then I-40 west. Petrified Forest charges $25 per vehicle and takes cards only. The park road connects I-40 at the north (Painted Desert) end with US 180 at the south end, so you can drive straight through and continue to Holbrook. Taking petrified wood from the park is a federal offense.

Days 9-10: Grand Canyon South Rim and Sedona

The South Rim is open all year. The North Rim is not part of a winter trip: it closes seasonally, and the NPS fee page notes it was closed for the 2025 season after the Dragon Bravo Fire. Entry is $35 per private vehicle for 7 days, cards only. Non-US residents aged 16 and over pay an extra $100 per person unless they hold an annual or America the Beautiful pass. Grand Canyon is one of the parks where this applies. Watch sunset from the rim, then on day 10 drive down to Sedona through Flagstaff and back to Phoenix. Check AZ511, the Arizona DOT's traveler information site, for I-40 and I-17 conditions. Both cross high country around Flagstaff.

Warm-weather variant: stay low the whole way

If snow is forecast for the north, or you simply want the warmest possible winter road trip, swap days 6-10. From Carlsbad, head back west via El Paso and Las Cruces to Silver City, then to Tucson and Phoenix. Spend the spare days in the Sonoran Desert, for example at Organ Pipe Cactus National Monument or Catalina State Park near Tucson. You lose Santa Fe and the Grand Canyon but keep the whole trip in milder, lower terrain. Texas fits too: the Big Bend and Marfa winter itinerary covers the same Chihuahuan Desert landscape further east.

Costs: park fees and fuel

Item	Cost	Notes
Saguaro National Park	$25 per vehicle	Both districts, 7 days, card only
White Sands National Park	$25 per vehicle	7 days, cash or card
Carlsbad Caverns	$15 per person 16+, plus $1 reservation	Reservation required even with a pass
Petrified Forest National Park	$25 per vehicle	7 days, card only
Grand Canyon National Park	$35 per vehicle (+$100 per non-US resident 16+)	7 days, card only
America the Beautiful annual pass	$80 US residents / $250 non-residents	Covers all of the above except the Carlsbad reservation
Fuel	About $280	1,850 miles at 28 mpg and about $4.20/gal regular, a blend of AAA's Nov 4, 2026 averages for Arizona ($4.38) and New Mexico ($4.02)

For two adults, the individual park fees add up to about $142, so the $80 annual pass pays for itself on this loop. For non-US visitors, the $250 pass costs less than one Grand Canyon surcharge for three people. Fees and fuel prices change, so check NPS and AAA before you go.

What travelers report

Winter weather reaches the south too. In a 2021 RoadTrip America thread on a November-December Southwest trip, a long-time moderator cautioned that even southern Arizona and West Texas can see winter weather. They said it shouldn't stop you, but you should be aware of it, especially if you're traveling by RV.
Watch the storm track and stay flexible. On a Fodor's thread about a Christmas-to-New Year's road trip across southern Texas, New Mexico and Arizona, posters suggested White Sands, Carlsbad Caverns, Chiricahua and Tucson's Saguaro. One traveler described the 2014-15 holiday ice storm that cancelled their West Texas reservations, and said keeping an eye on the forecast let them reroute around it.
Short visits are enough at some stops. In an older Fodor's thread planning a January-February trip, an experienced poster suggested about half a day for White Sands. They also found Saguaro's west district a more interesting drive than the flatter east loop. The trip planner eventually dropped Carlsbad Caverns as too far out of the way and possibly too cold. Another poster found motel lodging near the cavern entrance disappointing. That thread predates White Sands becoming a national park in 2019, so treat the details as dated.
Campers need to book far ahead. On the Escape trailer owners' forum, a couple planning a December Arizona camping trip in 2023 were told that Arizona state parks such as Catalina State Park near Tucson open reservations 12 months ahead. Another member recommended the Organ Pipe Cactus campground for its paved pull-through RV sites, which have no hookups.

What to watch out for

US 70 missile-test closures can hold you up for hours between Las Cruces and Alamogordo. Check the White Sands closure page the day before.
Mountain passes. US 82 through Cloudcroft, I-25 near Santa Fe, and I-40 and I-17 around Flagstaff can ice up. Check NMRoads and AZ511 each morning and have a backup route.
Holiday closures. White Sands closes on Thanksgiving and Christmas Day, and Carlsbad Caverns closes on Thanksgiving, Christmas and New Year's Day. Plan around them if you travel over the holidays.
Short daylight. December days are short. Schedule the long transfer days (3, 6 and 8) so you arrive before dark, especially on two-lane roads.
Forgetting the Carlsbad reservation. The $1 timed-entry ticket is required even with an annual pass.
Cash-only assumptions. Saguaro, Petrified Forest and Grand Canyon don't accept cash. Bring a card.

Bottom line

For a Southwest road trip in December, January or February, this Arizona and New Mexico loop gives you warm desert hiking in the south and the Grand Canyon in the north in 10 days with manageable driving. Buy the America the Beautiful pass, book the Carlsbad reservation, check White Sands closures and mountain road conditions daily, and switch to the low-elevation variant if a storm hits the plateau. For a shorter winter trip in the same desert, see the 4-day Big Bend road trip from San Antonio.
