13-Nights Classic Mexico Adventure - Classic from $2,399

Located on Mexico's Yucatan Peninsula in the fascinating Mundo Maya Region,
Merida provides a looking glass that reveals both colonial influence and the
mystique of an ancient civilization. In fact, the city is built on the exact
site of an indigenous ceremonial center.

Easily one of the best way to see Merida is by climbing into a calesa - a
high-wheeled, horse-drawn carriage. The city is also easily explored by foot.
As you amble past whitewashed houses, through lively marketplaces and around
the flower-filled Plaza Mayor, you'll begin to feel as if you've stepped back
in time. You can also visit one of Mexico's oldest cathedrals, built from the
stones of a Mayan temple, explore Paseo Montejo, a Parisian-style boulevard
lined with Victorian mansions, and visit the treasure-filled museums.

Wind down with the friendly locals in the welcoming bars and restaurants of
the old colonial district. If you want to travel even further back in time,
you'll find Merida is surrounded by one of the richest collections of Mayan
ruins in Mexico. Chichen Itza, Uxmal, Dzibilchaltun, and more are just a short
trip away.

On the outskirts of Palenque, located near the Mexico-Guatemala border approximately 300 mi/485 km southwest of Merida, lie some of the most impressive Mayan ruins in the country. Climb the tall Temple of the Inscriptions and then descend to the site of the impressive, restored crypt of the Mayan king Pakal. The crypt itself is closed off to visitors, but there's a replica at the Museum of Anthropology in Mexico City. Investigate other ruins to look at carvings and bas-reliefs.

We consider Palenque well worth a visit, but it is extremely hot and humid in the summer. To avoid the worst of it, get an early-morning start.

If you leave the park following the Otulum River down the hill, you will discover several excavated temples and get to many pretty waterfalls cascading into natural bathing pools, a great place to cool off after wandering around the ruins. Some pleasant hotels are found in the village, if you wish to overnight in the area.

If you have time, travel 60 mi/100 km south to the Agua Azul waterfalls. These turquoise cascades are some of Mexico's natural wonders (just try to ignore the tacky food huts dotting the lower end of the falls). You can swim there, but do so with care—several people have drowned.

Puebla, Mexico, located 80 mi/130 km east of Mexico City, has played an important role in the nation's history: The only Mexican victory over foreign invaders took place there when Maximilian's French Foreign Legion was defeated on 5 May 1862 (now celebrated as Cinco de Mayo).

Puebla has more than 60 churches (including its grand 16th-century cathedral) and a "secret convent" (it remained active after convents and monasteries were outlawed in 1857). It's known for manufacturing colorful tiles (dating back to the 1600s), as well as antiques, talavera pottery and mole poblano, a rich chocolate and chili sauce that was first prepared there by the nuns and has become one of Mexico's signature dishes.

Museo Bello contains an impressive collection of colonial-era art, and Santa Rosa Convent is fascinating for its enormous tiled kitchen and museum of local crafts. Other sights include the Bazaar of Toads (known for antiquities and antiques, not frogs); the Parian, an art market; the Art District, where tourists can gape at artists at work; and Los Remedios Church with El Popo volcano in the background.

Just strolling the city's streets is a treat, too: Many buildings are covered in gorgeous tiles, and shops display an irresistible array of Puebla's famous hand-painted talavera pottery.

From the Alameda, a leafy center of activity since Aztec times, to the Zona Rosa, a chic shopping neighborhood, Mexico City offers endless options to urban adventurers.

Founded by the Aztecs as Tenochtitlán in 1325, Mexico City is both the oldest and the highest (7,349 ft) metropolis on the North American continent. And with nearly 24 million inhabitants, it is the most populous city in the world. It is Mexico's cultural, political, and financial core -- braving the 21st century but clinging to its deeply entrenched Aztec heritage.

You only need to stand in the center of the Plaza of Three Cultures to visually comprehend the undisputed significance of this city. Here, the remains of an Aztec pyramid, a colonial church, and a towering modern office building face one another, a testament to the city's prominence in ancient and contemporary history. Located at the heart of the Americas, Mexico City has been a center of life and commerce for more than 2,000 years. The Teotihuacán, Toltec, Aztec, and European conquistadors all contributed to the city's fascinating evolution, art, and heritage. Although residents refer to their city as simply México (meh-hee-koh), its multitude of ancient ruins, colonial masterpieces, and modern architecture has prompted others to call it "The City of Palaces."

The central downtown area resembles a European city, dominated by ornate buildings and broad boulevards, and interspersed with public art, parks, and gardens. This sprawling city is thoroughly modern and, in places, unsightly and chaotic, but it never strays far from its historical roots. In the center are the partially excavated ruins of the main Aztec temple; pyramids rise just beyond the city.
