St. Helena is the second to last town as you head north along the Highway 29 corridor, with the highway itself doubling as the town's main street. That can mean a bit of traffic, especially during afternoon school dismissal. It's a small price to pay, though, for what can be an ideal base camp for your Napa Valley excursion.
The area has a long history, dating to the indigenous Wappo people (Robert Mondavi named his house and estate Wappo Hill). The current town is the resulting evolution of the settlement started in the 1840s by Dr. Edward Bale, who received a Mexican land grant. Henry Still founded the town in 1854, with Dr. George Belden Crane, an early influential vintner, arriving in 1855 (remnants of his vineyard and estate are now part of Salvestrin Winery).
Through the 19th century, the town's White Sulphur Springs drew San Franciscans, while the Gold Rush and the railroad spurred economic development. Following winemaker Charles Krug's first commercial bottling in 1858, the wine industry grew, and many of its historical landmarks, including the Beringer, Forni (now Freemark Abbey) and William Cole (now Ballantine) wineries, still stand. Prohibition brought difficult times and the area pivoted from grapes to prunes (the most important crop in the 1930s) alongside apples, cherries, pears, walnuts, plums and hops. Mature fruit trees and nut trees are still spread through verdant residential areas, contributing to St. Helena's reputation as the prettiest town in the valley.
Since the rebirth of the wine industry after Prohibition, St. Helena has become the valley's beating heart, with many prominent winemakers and vintners calling it home. Get up early enough and you may bump into some of them at the local coffee shops, fueling up for their day.
The St. Helena AVA covers just over 9,000 acres around the town, with Ehlers Estate marking the valley's narrowest point between the western Mayacamas and eastern Vaca range. The most densely planted sub-AVA in Napa Valley, with 6,800 acres of vines, the area takes in nearly 100 wineries. Included here are suggested tasting rooms on Spring Mountain as well, which rises above the town's western side.
While Yountville remains the culinary center of the valley, thanks primarily to chef Thomas Keller, St. Helena is no slouch. The town's best spots have a decidedly local-driven vibe, especially for happy hour and dinner, when many tourists head back down valley. There's a consistent theme of Cal-Italian cuisine, not surprising considering both the Italian heritage of agricultural families in the area and the fact that it's darn delicious with wine.
While downtown Napa continues to grow, St. Helena retains a bucolic charm. Its hotels are generally on the smaller side, which does put pressure on vacancies and, in turn, price; book your stay well-ahead and think about visiting during off-peak times of year (March and November can be lovely, for example).
