We did the 4-hour UTV/Rappelling Slot Canyon Tour and it was freakin' amazing! Rob was an amazing guide and we had a total blast!! We hadn't ever done any rappelling before but Rob was a great teacher and we were super into it by the end (and definitely wanna come back and to more/harder rappels!).
They had to change our tour time by a half hour because they were so busy, so they called about a week or 2 in advance about it, but it ended up working out great since we ended up just the 2 of us and our guide Rob!
The headquarters has a bathroom, a small fridge with some drinks for sale, and a bunch of cool merch for sale. You get there and sign waivers (if you didn't fill them out online already) and then get a bit of gear harnessed up on you plus a helmet. You want to leave most things in the car and only really take some water (though Rob also brought a bottle of cold water for each person), camera/phone, sunglasses, and maybe a hat (though you're wearing the helmet the whole time). No bathrooms on the trail (except some trees toward the beginning, so go before you go!
The UTV trip out to the hike and canyons was bouncy and fun and pretty. The initial hike wasn't super long but it was somewhat steep up some hills, mostly rock and sand, so maybe a little slippery at times, but not bad at all and definitely no scrambling or anything difficult. Then you have a bunch of rappels of different heights and hiking in the slot canyons and there some scrambling over or under boulders or shimmying through narrow areas. Rock climbing experience is definitely not needed and only a small amount of coordination is really needed! After the last rappel we walked out of the canyon and was right back at the UTV! The short drive back to base was like the drive going out and when we got back we took off the helmets and harnesses and that was it!
Rob mentioned they also run some local airbnb locations which sounded cool and if we book there (or another trip with EZE) then we'd get a discount if we told them we already did a trip with them. He also recommended Archie's food truck right next door and their food was indeed great (see my review of that for more info!).
