My TWW Take

Overall fun-ness

I really like the riding at Sweetwater Preserve. It’s usually the first trail network I hit when I’m in Tucson. It has a good mix of flow and tech to get me warmed up for desert riding and the cacti-studded landscape can’t be beat.

I also like that it’s a ‘one ride and done’ kind of place. You can ride most of the trails in a single ride, so it feels like a good accomplishment, especially for your first day in Tucson.

As far as ‘fun-ness factor’, Sweetwater Preserve delivers! The descent down Desperado is a blast and there are little pockets of tech to keep things interesting.

Average difficulty

Even though the trails at Sweetwater Preserve are pretty much all rated Green (easy) and Blue (intermediate) on TrailForks, there are actually some short and sweet technical sections. They don’t warrant at Black (expert) trail ratings, but they could be a good challenge for some riders to session or keep more advanced riders on their toes. See “Best Trails to Ride” below for more info on what to expect on each trail.

Trail variety

There’s not a ton of trail variety at Sweetwater Preserve. I’d say it’s desert cross-country with a sprinkle or two of ‘enduro’. But don’t let that hold you back from riding these trails. I really enjoy them and I think you will, too!

Best trails to ride

There aren’t too many trails at Sweetwater Preserve and as I mentioned above, you can fit most of them into one ride if you want to. Here are what I consider the ‘best’ trails:

Desperado: If you’re a beginner or are riding with kids, this is a great loop to do on its own. The ridgeline descent is beautiful and the climb is built well so you don’t have to work hard for your reward. Ride it counterclockwise for the most fun descending.
Black Rock Loop: This isn’t my favorite trail, but it’s worth adding on if you want the miles. It’s a bit loose and chunky in places. I usually ride it counterclockwise, but it would be fine clockwise, too.
Redtail Ridge: A beautiful trail with some surprisingly techy stretches.
Red Canyon: I like this trail better than staying on Homestead. It’s more scenic and interesting.
Wildflower Ridge: The east side is a nice mellow climb and the west side is the best ‘techy’ descent at Sweetwater Preserve

Route recommendation

Easy Out and Back: Desperado is one of the best trails at Sweetwater. It’s fast and flowy and super fun! This route climbs up to the top of Ocotillo Hill and then reverses for an awesome descent.
Tour de Sweetwater: This route is the classic way to link up the trails at Sweetwater Preserve if you’re looking to do them all. It’s my go-to loop whenever I’m at Sweetwater.
Make it shorter: Here are two ways to make this route shorter:
Skip the Black Rock Loop. Honestly, it’s not my favorite anyway
Skip the double-back on Red Canyon and just continue onto Redtail Ridge after climbing Ocatillo Hill
