The Colchagua Valley wineries had the good sense to band together back in the 1990s, when Chile's latest wine boom was just starting. Founding the Ruta del Vino de Colchagua has paid off handsomely, not only for marketing but organizing world-class wine tourism. It's no joke; Colchagua was named "World's Best Wine Region" by Wine Enthusiast in 2005—which locals are very happy to mention. The Wine Route's office, next to the Santa Cruz Plaza Hotel on the main square, provides basic information about its 13 member wineries and arranges guided tours in English to most. Though most wineries have their own guides, few of them speak English, and some only accept visits arranged by Ruta del Vino. The office arranges tours to two or three vineyards, with or without lunch, starting from 49,000 pesos per person and up, depending on the complexity of the tour. The harvest season—March and April—kicks off with the Fiesta de la Vendimia (Grape Harvest Festival) and is always a great time to visit.
