Lounging on a beach with a tropical drink at a resort in Cancun or Tulum makes for a great escape from the frozen tundra. That's why so many Minnesotans — myself included — head to the Yucatan, that peninsula at the southern tip of Mexico that splits the Caribbean Sea and the Gulf of Mexico. Sunshine is abundant. Thoughts of snow melt with the warmth. Relaxation rolls in with each wave.

But I've also ventured beyond the popular Yucatan beaches. During my last trip, I stayed in Merida, a landlocked city with a rich Mayan and colonial history. On day trips from there, I found places with more locals than tourists, I searched for alligators and flamingos, swam in caves and bumped down remote roads that led to shockingly pink waters, where river and the Gulf of Mexico meet.

Each of these off-the-beaten-path places is alluring in its own way, and visiting them is surprisingly easy. In fact, some of the locations I've explored — all hidden oases of the Yucatan, within an hour or two of Merida — can be easily experienced during a day trip from the Yucatan's Caribbean side. As for the beach chair back at the resort with your name on it, well, it'll be waiting for you.

Ria Lagartos

As my partner Joel and I climbed onto a small boat, a fisherman approached us. He showed us his day's catch of a not-so-ordinary-looking fish. Then he wished us luck in capturing an alligator.

I wondered about that comment, even though the small fishing village of Rio Lagartos translates to Alligator River. But we weren't here after a 2½-hour ride from Merida to catch anything, least of all a scaly reptile. We'd come to explore the bird-rich tangle of nature on the town's edge known as the Ria Lagartos Biosphere Reserve.

The 233-square-mile reserve holds mangrove forest, saltwater estuaries and sand dunes — and about 400 species of birds, including snowy white ibis and brown pelicans. It's most known, though, for its vast population of flamingos, said to be the largest in Mexico.

We cut our hourlong boat ride short because of an impending storm, so we didn't make it to the flamingos' nesting site. We were, however, mesmerized by the number of beautiful birds we encountered. In the end we spotted one alligator and a handful of visitors with white clay smeared on their bodies for its alleged healing benefits. A beautiful sunset greeted us as we made our watery way back to our car.

Las Coloradas

After our adventure along the river, we took a short drive to "the pink sea of Yucatan" known as Las Coloradas. These saline lakes appear in otherworldly hues of rose and pink, a result of high concentrations of algae, shrimp and other organisms. Flamingos, which are gray early in life, become pink after feeding on the organisms in the colored saltwater. It is prohibited to go into the water. There isn't much infrastructure for travelers — bring your lunch — but the scene is worth the drive (thetravelblog.at/pink-lagoon-las-coloradas/).

Choco-Story Museum

About 40 miles south of Merida, Joel and I hiked through the ancient Mayan city of Uxmal, where archaeological finds include a pyramid, palaces and other buildings that are among the best preserved Mayan ruins in the country.So after exploring Uxmal, a popular tourist site, we didn't expect much in comparison when we dropped in at the Choco-Story Museum across the street. But the museum offered far more than anticipated.

We learned about the history of cocoa and its importance to the Mayan people. I was even more surprised by the museum grounds, where paths cut through lush vegetation, past an array of parakeets and to a visit with rescued spider monkeys. We also saw a re-enactment of a Mayan shaman cleansing. And then there was the gift shop: Let's not forget about the amount of chocolate I coveted (choco-storymexico.com/uxmal---ingles.html).

Cenote Hacienda Mucuyche

One of the most unusual natural wonders in the Yucatan Peninsula are its cenotes, sinkholes created by the collapse of limestone. There are 6,000 of these pools in the Yucatan. They were once used as religious places for the Mayan people, who considered them sacred wells. Today, many offer rappelling activities, diving equipment and rope courses.

Among my favorites are Cenote Hubiku in Valladolid, and Cenote Hacienda Mucuyche in Abala. One day, we set out from Merida to find Mucuyche. After an hour's drive, we came to a village where thatch-roofed palapas lined dirt roads, their inhabitants sleeping in hammocks. A wooden sign with "cenote" carved into it seemed like a good omen. Horses were tied to a tree. The crowing of roosters penetrated the air. At the entrance to a deep cave, life jackets dangled from a rope. We were invited to visit the small family cenote for a small fee, but it wasn't Cenote Hacienda Mucuyche.

"Down the street, two blocks to the left," a man instructed. We soon came upon a large stone gate — and our destination. We waited to buy tickets behind a handful of mostly Mexican tourists. Inside, we were led on a brief tour through what remained of a beautiful, historic hacienda that once housed a wealthy family. Then we followed a winding path lined by trees that led to a cave with turquoise water. It was magical, peaceful and tranquil.

A guide led us, wading, through the pools into a dark cave. I put on the goggles the site provided, dipped my head into the water and saw a wonder of the world. That may be an exaggeration, but it looked like New Mexico's Carlsbad Caverns, only underwater. Stalactites seemed to go on forever.

Back into the light, we floated down a long green stream lined by pothos vines to a subterranean waterfall.

Like most cenotes today, Hacienda Mucuyche has locker rooms and a restaurant where local Mayan women make homemade corn tortillas (cenotes haciendamucuyche.com/en).

Celestún

The small fishing village of Celestun, about 60 miles from Merida, is near the Celestun Biosphere Reserve, a main courtship area for greater pink flamingos who flock there during fall and winter. Tour guides on the beach wait under palapas to take visitors on small-boat excursions to see the flamingos and freshwater springs. We opted to lounge on the secluded white-sand beach, which we shared with locals, cold beers in our hands. It was just another day on the Yucatan.

Xcaret

The only tourist trap we encountered was Xcaret, a park with a $100 entrance fee, in Playa del Carmen. It felt like a zoo by the ocean, but there was one part that we found phenomenal: the cultural area that included a maze through a makeshift Mexican cemetery, a Mexican rodeo and a big cultural show at the end of the evening that was worth the price of admission alone.
