Trail Description:
Fairly smooth ride with occasional fun on blacktop, dirt road, single trails, and even through a tunnel under Rinaldi. Some nice steep sections, too. The full route takes you from the bottom of this trail, goes 3 miles to the top, then turns around and and comes back down for a good downhill leg. Should take about an hour if you're good, 1.5 hours if you're me.
How to get there:
Start near the maintenance yard just north of Devonshire and Tunney and follow the Mission Trail all the way up Limekiln Canyon to Sesnon.
Additional Notes:
The tunnel under Rinaldi is passable almost all year. The rocks and pools shift after a rain.
