After staying out way too late the night before, had a brutally dusty morning at Upper Antelope Canyon. It really does live up to its reputation, especially if you can get a tour starting between 10:30am and 12:30pm or so (depending on time of year). But make sure to be prepared for tons of dust, most companies use open-sided trucks to transport you, so everything gets dusty as hell. Only one company uses enclosed vans, and given how popular the tours are, you probably won't have much choice in who you book.
After doing two different tours that moring, indulging in the light beams and dust that Upper Antelope Canyon is so popular for, have to say that Antelope Canyon Tours's open-sided trucks were more than balanced out by their very personable tour guide who loved taking pictures. By comparison, Antelope Slot Canyon Tours felt like a very mechanical, very precise machine for their (also very experienced) tour guide as he cranked through instructions on camera settings and took photos with less artistry. Their vans were a much superior experience to the open-sided trucks, tho. Both companies have multiple guides so your experience may vary.
Lower Antelope Canyon was next. Only two companies here, used Ken's Tours, which had very knowledgable and friendly guides who had a strong local's view-- very cool. The waves and arches and formations here aren't as spectacular as the upper canyon, but they still have plenty of Instagram-worthy formations. Strongly suggest doing Lower Antelope Canyon before Upper Antelope Canyon so you don't get spoiled by the latter first!
Had an okay dinner at State 48 Tavern. Solid drink selection, they admit up front they serve USDA choice beef (and did a pretty decent job at it!), but the steakhouse soup was kind of gross and the vegetable side never arrived. Potato salad was pretty good tho?
