6 Best Sights in Oaxaca, Mexico

The recently excavated Copalita archeological site is just 10 minutes from Huatulco's sleek hotel zone (a MX$70 taxi ride from La Crucecita's main plaza) but feels like a step back into another era. The well-designed site, a joint project by FONATUR and Mexico's National Institute of Anthropology and History, features the restored archaeological remains of the ancient city of Copalitan, occupied by the Zapotec and Mixtec peoples as far back as 500 BC. Plan to spend a few hours browsing the modern museum and its well-curated collection of ceremonial objects such as obsidian knives, jade jewelry, and funeral masks, and leave time for a stroll beneath a canopy of tropical trees to reach a spectacular cliff-side lookout across the Copalita River. Along the way, there are restored buildings from the Classic Period, including the Serpents Pyramid, a ball court, the Great Temple, and a pre-Hispanic lighthouse. Take insect repellent, a hat, water, and sturdy walking shoes.

Although several hotels, shops, and restaurants (serving mostly lunch and dinner) are near the main road, Boulevard Benito Juárez, the area is still being developed. A marina is located at the eastern end of the bay. Playa Chahué itself has a negative reputation: people reportedly drown here more than water conditions seem to warrant. At the main beach you'll find a swimming pool, changing rooms, restrooms, a restaurant and bar, children's playground, and shaded lounge chairs at the Hotel Castillo Club de Playa Chahué (admission MX$100). Amenities: food and drink; parking. Best for: walking; partiers.

The aquamarine, calm waters of this bay are a nice spot for swimming, although the area can be busy with tourists, vendors, and touts when cruise ships are in town. This is the most developed of Huatulco's nine bays. Browse for quality keepsakes in the upscale shops; dine with your toes in the sand at a seafood restaurant; mingle with the locals in the central zócalo; stroll the promenade; or just sip a cool drink and take in the lively beach scene. You can arrange boat tours, snorkeling excursions, and fishing trips at the marina. Amenities: food and drink; toilets. Best for: swimming; walking.

One of the largest and most impressive bays in the Huatulco area, Tangolunda is also the most developed, with a string of luxury hotels, a golf course, and a small shopping mall with restaurants across from the Barceló hotel on Boulevard Benito Juárez. It's about 10 minutes by taxi or bus from La Crucecita. The most swimmable section of the beach is at the easterly stretch near Dreams Hotel. If you're not staying at one of the hotels, there are few amenities directly on the beach, but you can inquire about a day pass at the Barceló or Dreams. Expect to see lots of vendors plying wares such as silver jewelry and inexpensive wooden toys. Amenities: food and drink; water sports. Best for: swimming; walking; snorkeling.

This hub of commerce most closely resembles a real Mexican town. Its leafy central plaza is flanked by the Parroquia de Nuestra Señora de Guadalupe church, whose interior is covered with hand-painted frescoes; on the ceiling is an impressive fresco the locals claim is the world's largest image of the Virgin of Guadalupe. You can dine, hang out at a bar or sidewalk café, enjoy an ice cream, and browse in boutiques. You'll also find ATMs, a modern bus station, and Internet cafés here.

If you're looking for the best fishing and water sports in the area, head to this beach west of Bahía Santa Cruz, where dozens of fishermen aren't shy about offering their services from the moment you set foot in the sand. It's a great place to head out on a fishing boat in the early morning (negotiate a price with one of the captains on the beach); when you come back to Playa Entrega, have one of the little seafood restaurants on the beach cook up your catch. Lobster fishing is another option, as are snorkeling and kayaking. The calm waters are good for children or timid swimmers. Amenities: food and drink; water sports. Best for: swimming; fishing; snorkeling.
