Tucson is one of the few cities in the world completely encircled by mountains, creating a dramatic and scenic backdrop.

Water Bodies (Rivers, Lakes, Waterfalls)

Once a perennial river, its flow now is mostly ephemeral due to groundwater pumping and dam construction upstream, though treated effluent has restored a perennial flow in certain stretches through the city. The river's floodplain was the site of some of the earliest agricultural irrigation in North America, dating back over 4,000 years .

Landmarks

Mission San Xavier del Bac

Known as the "White Dove of the Desert," this magnificent Spanish Catholic mission is the most iconic landmark in the Tucson area. Founded in 1700 by the Italian Jesuit priest Eusebio Francisco Kino, the current church building was constructed between 1783 and 1797 . It is a stunning example of Spanish Colonial architecture with a beautifully ornate, sculpted facade and a famous interior filled with original statues, frescoes, and carvings. Located on the Tohono O'odham Nation San Xavier Indian Reservation, about 10 miles south of downtown Tucson, it remains an active parish and a place of pilgrimage.

El Tiradito (The Wishing Shrine)

Listed on the National Register of Historic Places, El Tiradito is a unique and melancholic shrine located in the historic Barrio Viejo. It is the only place in the United States dedicated to a person buried in unconsecrated ground, a young man who, according to legend, died a sinful death. Visitors light candles and make wishes by placing them in the crumbling adobe walls of the shrine, a tradition that has continued for over a century .

The Turquoise Trail

For a self-guided tour of Tucson's history, the Turquoise Trail is a 2.4-mile paved walking trail through downtown . A project of the Presidio Museum, the route is marked by a painted turquoise stripe on the sidewalk. It connects over 20 historic sites, including the site of the original Presidio San Agustín del Tucsón (near the modern Pima County Courthouse), the historic Railroad Depot, the beautiful St. Augustine Cathedral, and numerous examples of 19th-century adobe architecture . The trail is also an open-air art gallery, featuring iconic murals like the El Tour de Tucson mural and the multi-story La Mujer Empoderada .

Sentinel Peak / "A" Mountain

This volcanic hill just west of downtown is the very "black hill" (cuk ṣon) from which Tucson gets its name . It is more popularly known as "A" Mountain for the large, white "A" (for the University of Arizona) that was constructed on its slope in 1916. It offers a panoramic view of the entire Tucson basin and is a popular spot for watching sunsets.

Old Tucson Studios

Located in the Tucson Mountains, this attraction began as a movie set in 1939 for the film Arizona.

Tucson's Culinary Landscape: A UNESCO City of Gastronomy

Tucson's food scene is unlike any other in the United States, a distinction officially recognized in 2015 when it was named a UNESCO City of Gastronomy, the first in the country . This honor is a testament to more than 4,000 years of uninterrupted agricultural history, a rich tapestry woven from Indigenous, Spanish Colonial, Mexican, and Anglo influences .

The Foundation: 4,000 Years of Food History

Tucson's culinary story begins with the desert. The Tohono O'odham and other Indigenous peoples cultivated the "Three Sisters" (corn, beans, and squash) using ancient irrigation canals, some of the oldest in North America . They also foraged for over 200 edible desert plants, a practice that continues today. You can experience this living history at Mission Garden, a living agricultural museum where heritage crops like tepary beans, Devil's Claw, and Seville oranges are grown just as they were centuries ago . Nearby, the San Xavier Co-op Farm continues these traditions, offering mesquite flour and other Indigenous foods for sale .

Iconic Dishes and Where to Find Them

The fusion of Indigenous ingredients with Spanish-introduced wheat and cattle created the foundation for Sonoran-style food. This unique cuisine is best experienced at legendary local spots.

The Spirit of the Desert: The Agave Heritage Festival

Agave is more than just the plant used for tequila and mezcal; it's a cultural touchstone. Described as "the buffalo of the plant world" by Indigenous peoples, agave has been used for food, fiber, and ceremony for millennia . Tucson celebrates this remarkable plant every April at the Agave Heritage Festival. What began as a one-day event has evolved into a multi-day festival featuring seminars, tastings, and themed dinners that explore the biodiversity, sustainability, and cultural significance of agave . You can also taste its modern applications at bars like Juniper, which features a signature cocktail with prickly pear syrup, or at the subterranean BarBata, known for its extensive "From Agave" drink menu .
