2 Best Sights in Central Maipo, Side Trips from Santiago

The De Martino family has been making wine in Isla de Maipo since 1934 and were the first in Chile to bottle Carménère, now Chile's signature grape. The winery is a strong proponent of organic viticulture. Its winemaking team has done groundbreaking work in seeking out the country's finest terroirs. Tours and tastings are run at a variety of price points and interest levels, and there's an elegant lunch for a minimum of seven people and buffet for less. Several vegetarian entreé options are available alongside meat and seafood.

Don Francisco Undurraga Vicuña founded this traditional winery in 1885 in the town of Talagante, 34 km (21 miles) southwest of Santiago. Today you can tour the gardens—designed by George Dubois, who planned Santiago's Parque Forestal—or take a look at the facilities and enjoy a tasting. Reserve ahead for a spot on a tour in English or Spanish. Viña Undurraga is along the way to Pomaire, so you might visit both in the same day. Private tours for a minimum of two participants begin weekdays at noon and must be reserved two days in advance at a cost of 28,000 pesos per person.
