I'm really confused about the not being hardtail friendly comment. There are few trails in Tucson more hardtail friendly.

The worst part about this trail is the very rough gravel road to get there. Better to park near paved road and ride up via hohokam trail. Once there you’ll find the trail flowy and fast. Scenic too as it’s about 4,000 ft elevation.

Very fun trail. Climbs rewarded with fast and flowy downhills. The gravel road up to the trailhead is quite bumpy. In higher elevation so less cactus hazard.

Great trail! It’s a very nice break from the typical sand and cactus. The climbs is definitely worth it for the DH you get in return. Excellent Burms. Overall a great quality trail! Will be in me and the wife’s normal rotation.

Trail Daheste Loop
This trail was still being worked on when i rode it with my wife and some friends last weekend. I am a fairly new rider. This is only the third trail I’ve ridden. But it was the most fun i have had so far on a mountain bike. There was a lot more climbing than i was used to. But the down hill sections are amazing! The berms are perfect. I have a hard tail and i felt great going as fast as i could. My only complaint is at this point with the trail being so new, it was kind of tough to find the south loop. But our friend found it and we had a great time. There is no shade at all and if you think you have plenty of water, bring more. But other than that, it is great!
