Bring water, chow and extra tires. Serious technical short and long climbs will challenge the sickest riders and you can easily put together an all day ride without ever doubling your line. Lots of slick rocks, H2O crossing, mud and switchbacks. This is my fav. It has every kind of riding you can think of.
Trails are very well marked and maps are available at headquarters.
I ride here 2-5 days a week. It's taken me a few years to figure the place out, but the place has it all from steep loose granite to smooth,flowing singletrack. Most people park at HQ and bike up fire road, ride single track, then ride the fire road back down. Let me tell you that is a big waste of effort. There are many better ways to stay on single track the entire time and get more downhill than uphill.
