Climb Summary


Trinity West

 Trinity West ranks #12 on the Tri-County Top 25 list with Fiets Index of 3.67. This is a favorite climb for local cyclists and is one of the few connectors between Napa and Sonoma Counties.  The views are not spectacular, but the climb is challenging and generally a steady 6-10% from start to finish.   The finish of this climb is at the intersection of Cavedale and Trinity Roads at the Mayacamas Volunteer Fire Station where there is normally water and a cycling pump - it is "cyclist friendly." [Thank you MVFD!].

Start is just east of Hwy 12

Dry Creek/Trinity East


    Another challenging climb is Dry Creek Road/Trinity Road East (Dry Creek becomes Trinity Road a little over halfway up the climb).  This ascent is almost a match for Trinity Road West (west 2.9 v. east  2.7 miles and 8.8% west v. 8.3% east).  There is more shade on the east side and, apparently because it is in Napa County, the road is a bit smoother.  

Start at the bridge at the bottom of the climb - you will know where the start is, trust us!

Note that Dry Creek / Trinity East does not summit at the same location as Trinity West as the road connects the two endpoints along a relatively flat .6 mile ridge line.

 Traffic/Roadway surface:  This is a narrow 2 lane road that is very hazardous to descend.  On this descent, riders encounter rough road, gravel, unexpectedly sharp and technical turns on steep grades.  There have been many serious cycling accidents and some rider deaths on this  road over the years.
