Just two years ago, the restaurants and shops in this colonial Mexican city were closed off to outsiders after protesters and soldiers briefly turned it into a battleground. Now, peace has returned, and so have the tourists.

One of the most diverse places in Mexico, the city and its surroundings are a treasure trove of indigenous crafts and a destination for history buffs seeking a firsthand encounter with ancient civilizations. But one of the main reasons to go is the food.

VISIT the capital of the "cloud people" -- the ruins of Monte Albán on a mountain over the city. Look down over the valley from atop pyramids and explore fields where the ancient city’s inhabitants once played a mystical ball game (monte-alban.com).

EAT mole, the rich chocolate and chili sauce that is the region's signature dish, in the tiny dining room of Maria Bonita (52-951-516-7233). Buy some at the Benito Juarez Market to take home.

SHOP for whimsical wooden sculptures known as alebrijes that are inspired by the artists' dreams, and black clay pottery from nearby villages along Alcalá, a pedestrian street lined with galleries and cafés.

SAMPLE delicate shaved ice in flavors like rose, tequila and burnt milk sold by vendors in the shady plaza next to one of the city's many stunning churches, La Soledad.
