INTRO
This climb shares is the first 5 1/2 miles of the most difficult climb in the North Bay Area (Mt. St. Helena). Old Lawley Toll Road intersects with Hwy 29 just before the highway pitches up for its 5 mile climb to Robert Louis Stevenson State Park (OLTR runs roughly parallel to Hwy 29 for 3 miles until intersecting it again a little over halfway to the pass).
