This loop assembles just about all of what Flagstaff has to offer in one ride. The climb up Brookbank and Oldham is steep and a little technical, but a ton more fun than the fire road.
The ride on the ridgeline at the top of Sunrise and into the Hobbit Forest offers spectacular views. Little Bear, albeit damaged from fire and flood, is absolutely fantastic downhill singletrack. Arizona Trail and Secret Trail offer classic hardpack singletrack with some climbing.
Moto Trail brings the gnar and will make you work all the way down. Last but not least... end the ride with the classic Schultz Creek Trail downhill.
