Climb Summary

Climb Summary

This is an exceptional, yet brief, climb in the northwestern section of  Napa Valley.

Start of climb affords wonderful view of the mighty Mt. St. Helena just across the Napa Valley

This climb more than any other in Napa County offers a  legitimate redwood forest-like experience.  Although there are negligible  vineyard views throughout the climb, we are treated to a near-private ride, completely shaded by a canopy of tree branches (redwoods for much of  the climb) and one spectacular photo op of Mt. St. Helena 8 miles north.  We highly recommend this short up-and-back climb for those travelling  through or near Calistoga - you will not be disappointed.

   Traffic/Roadway surface:  This is a very narrow road (essentially one  lane towards the top) with no center line, rough pavement and a fair  amount of loose gravel and debris (careful on the descent).  However,  there is very little traffic along the climb and we rank this as a fairly safe  ascent.
