FULL SUMMARY

Napa is a wonderful area for bike riding and climbing.  Located in the heart of California Wine Country, there are wonderful vineyard rides in the Napa Valley, but also some challenging and scenic climbs up and away, from both the western and eastern sides of the Valley.

Mt. St. Helena

THE ONLY 360 DEGREE VIEWS IN NAPA VALLEY

Cycling Mt. St. Helena - view of Mt. St. Helena across vineyards 

View of Napa Valley from Mt. St. Helena.

Mt. St. Helena is the most difficult bike climb in the Northern Bay Area and offers 360 degree views from the top.  Note however, that, while we have navigated the rugged second half of the climb on a road bike with 28mm tires, this climb is best attempted on a gravel bike with knobby tires, or even a mountain bike.

Spring Mountain

SECOND HARDEST CLIMB IN NAPA VALLEY

Bicycle climb Napa County - Spring Mountain Road - pond, vineyard, mountains 

Surrounded by hillside vineyards on this climb.

Spring Mountain Road is our favorite route to and from Napa and Sonoma Counties.  This climb passes through beautiful mountainside vineyards while challenging us with extremely steep grades, particularly over that last 1.7 miles which average 12.2%.

Oakville Grade

STEEPEST 1 MILE IN NAPA COUNTY

Ride from Oakville through pleasant vineyards to the start of one of the steepest mile segments in California (#1 Napa County, #6 California,  #19 US).
