Take in awesome views on a hike to the summit of the highest peak in the California Wine Country. You might forget you came for the wine when you gaze upon the stunning panorama at the 4,342 summit of Mount St. Helena in Robert Louis Stevenson State Park. The peak north of Calistoga looms large above the rolling hills of Napa and Sonoma counties in the Northern California Wine Country. The five-mile hike to the summit has over 2,000 feet of elevation gain, so be ready for a workout. The hike starts on Stevenson Memorial Trail, climbing just under a mile and passing through the area where the famed author Robert Louis Stevenson ("Kidnapped," "Treasure Island) honeymooned with his new bride in 1880. Next in line is the Mount St. Helena Trail, an old logging road that climbs to the summit over about four miles. Note your turn-off point or you might miss it on the way back. While the wide dirt road to the summit lacks the appeal of a single-track trail, the eye-popping views of the terrain below are a welcome trade-off. Best time to go: Clear winter days will offer the clearest views, especially a day or two after a storm goes through. Spring and fall should be gorgeous, but summer will probably be too hot and the Wine Country too crowded.
