Sunrise, 90mins tour for group of 5 novices. $120 per person minus 10% discount + tax + tip.
I think many of their customers are more advanced, but they were great/patient / friendly with our group of novices/never been on horse. Walked with occasional trot. One guide gave some running discussion about flora / natural history; perfect since we just wanted to ride and see, didn't need a cowboy shtick. They showed us a little peak, a valley, a juniper tree made into a "clubhouse"...
All in all perfect for us East Coasters who just wanted a little taste of the desert. They pick up from Four Seasons.
