    San Xavier Del Bac Mission - Vendors

    San Xavier Del Bac Mission

    I've been coming to San Xavier del Bac for a couple years and never wrote a review and honestly it…read moredeserves one. First things first the fry bread here is elite. Fresh hot and made by local vendors right out front. It's one of those simple things that just hits every time. Add in the little stands and gift shops and it turns into a whole experience not just a quick stop. The mission itself is absolutely stunning. The architecture alone will stop you in your tracks bright white against the desert with intricate details that feel almost unreal. It's still an active church which makes it feel even more special. You'll see people praying attending mass and just quietly taking it all in. The energy here is calm but alive. They host events swap meets and markets too and when they do it's packed. The community really shows up and it's cool to see so many local vendors getting love and support. That said learning the history here adds a layer. Missions like this were part of Spanish colonization and while they're beautiful that history is complicated and at times deeply painful for Indigenous communities. This mission was originally established in 1692 by Father Eusebio Kino in an existing O'odham village and the structure you see today was built in the late 1700s with O'odham labor. It's important to appreciate the beauty while also understanding the full story behind it. Overall this is one of Tucson's most iconic spots for a reason come for the fry bread stay for the history and take a moment to really appreciate where you are.

    This place was listed among Tucson's unique attractions, and it was a relatively short drive so we…read moreadded it to our itinerary. The site is less than 15 minutes south of downtown via a couple of interstates. Once you exit it is probably only a mile or so. The mission complex is located on a tribal reservation. You turn off the paved road to a large field of dirt and gravel in front of the mission. The center part of this is given over to semi-shaded stalls for vendors - food like fry bread, etc. Parking is along the sides. When we visited, the facade was partly covered with construction scaffolding, but this was wrapped with tarps that reflected the building beneath it. So you could still get a good idea of how it would look uncovered. Inside, there is the main church on the left (as you face it). This is actively used, so be quiet / respectful. Passing through there (or entering separately on the right) there are several smaller connected rooms that have displays about the history of the building and the local area. In back is a courtyard with a fountain. I'm not sure the public has access to this, but you can view it from a shaded arcade. If you like historic buildings or old missions in particular, this is an easy stop within the Tucson area. And the fry bread we got as we left the parking lot was good too!

    My son brought me here for my birthday yesterday, it was such a wonderful experience! I have lived…read morein Arizona for over 20 years and this was my first visit. I was so excited when we arrived, he didn't tell me where we were going. I love that it is a self directed tour of the facility, we totally took our time and enjoyed every view. Right as we started we saw wild turkeys in the grass, that was awesome because neither of us had seen one outside of pictures before! I loved seeing all the art along the trails, my favorite was the solar tree. Inside the facility you view the kitchen and dining area first, it is really cool that they still have the original table and chairs there. All along the way there is staff saying hello and ensuring that all is well. After completing the walking tour, we went on a behind the scenes tour of the Lung. That was fascinating!!!! I highly recommend adding that on when you go. Not only was this a walk through some history, it is also a visit to science in action, they are working on some amazing projects that are very exciting. Biosphere 2 is great for all ages, however, there is a lot of walking, both downhill and uphill, so be prepared and bring water!!!

    In the late 1800s, the Biosphere 2 property was part of the Samaniego CDO Ranch, which grew as the…read moretown of Oracle did. Nearly 50 years later, the ranch was sold to a Canadian dentist who then ran it as both a cattle farm and hunting lodge, from the 1920s - 1950s. When he passed, it was sold to Lady Margaret, Countess of Suffolk, who built a Spanish-style adobe home, servants' quarters, and a pool on the property. She lived there until her death in 1968 after which Motorola purchased the property and built both casitas and a conference center. In 1984, Space Biospheres Ventures bought the property and began construction of the current $150m facility two years later, aimed at research and development of self-sustaining space-colonization technology. It included forests, deserts, laboratories, recycling systems, pigs, chickens, hummingbirds, bush babies, and even a coral reef. The University of Arizona assumed it in 2011 and is still used as a major scientific laboratory and educational center focused on global ecology, climate change, and earth sciences. What It's Famous For If you remember the movie Bio Dome (though not filmed at the Biosphere 2) then you know the premise of what happened within Biosphere 2. Two missions, between 1991 and 1994, sealed "Biospherians" inside the glass enclosure to measure survivability. Unfortunately, low oxygen levels, coupled with dwindling food supply and a bit of hysteria, ended both experiments early. To read first-hand accounts of what it was like, click here. Is It Worth Touring? It was actually a good way to spend an hour! We toured the various areas within the domes, explored some of the outside areas, and learned a lot more about the work being done today!
