Hiking the Huge Mountains of Mexico City: Izta-Popo National Park

Unless you’re looking out of an airplane window, you might not even notice that Mexico City is surrounded by mountains, including the second and third highest in the entire country. You can see the green slopes and sometimes snow-capped peaks off in the distance when you finally escape the dense neighborhoods of the mega-metropolis.

At least ten national parks are within driving distance of the the city, meaning hiking trails, ziplines, ATM rentals, old ruined convents, waterfalls, caves, and expanses of pine forest. You might even get lucky and see animals like weasels, the tiny teporingo rabbit, white-tailed deer, long-tailed wood partridges, horned lizards, tarantulas, and rattlesnakes. Don’t be afraid of these last two–they’ll leave you alone if you leave them alone.

What you should make you cautious, however, are badly-marked trails and some safety issues, especially robberies. So if you want to go hiking near Mexico City, go in a group, stay on the most obvious trails, and come prepared with rain gear, layers of warm clothing, food, and lots of water. Also, choose a national park where you must pay an entrance fee and can park in an official parking lot, which will greatly reduce (if not eliminate) the possibility of criminals on the trail.

If the trail takes you high into the mountains, even better. For all these reasons, Itza-Popo National Park is probably the best for a day of hiking near Mexico City. I’ll write about other places in later posts, like the Cubres de Ajusco and Nevado de Toluca national parks.

You’ll need a car to get to there, or else pay for a long taxi or uber ride. Driving there is straightforward–just follow directions on Waze or Google Maps to the Paso de Cortés (Cortés’s Pass), where the park entrance is located. Get up early; the best light for photographs is in the morning, and rain is most likely in the afternoon, especially in summer.

Izta-Popo National Park

The two tallest mountains next to Mexico City, which are also the second and third highest in the country, are actually volcanos, one active and one long extinct. Active Popocatépetl has that classic cone with a wisp of smoke coming from the crater, while Iztaccíhuatl has a rocky, broken peak that gives few obvious clues to its volcanic origins.

Both of these pre-Hispanic names are quite a mouthful, so they’re usually abbreviated as Popo and Izta (pronounces EES-ta). They were revered as gods by the native Mexica, along with neighboring peak Tlaloc, named after the rain god.

In the Nahuatl language, Popocatépetl means “mountain that steams,” as it’s been active since ancient times. Iztaccíhuatl means “white woman”–like many mountains in the world, people have identified the features of a reclining body in its crags and cliffs.

Popo is off-limits to hiking because of regular activity; big eruptions happened most recently in 2000 and 2005, and it ejects long columns of smoke nearly every day. So the spot for hiking is on Izta, a long, arduous and high-altitude hike that’s only for the experienced and in good shape.

A less difficult hike is the Alpino trail, which follows the saddle between the two mountains. It begins at the parking lot at the entrance to the park and ends at La Joya, the name for the area that has the parking lot for the trail up Izta. Cars can take a winding dirt road to La Joya; the Alpino trail is roughly parallel to it but follows a higher ridge, with the road mostly out of sight.

Hiking Alpino takes about two hours each way, there and back, and has great views of both mountains. If you have enough time, you can continue up the trail to Itza for an hour or two for more great views and a taste of big-mountain experience.

When you arrive, first visit the park office to register and pay the 57-peso per-person fee. Then you can decide whether to start on the Alpino trail right there or continue driving to La Joya, where the hike up Itza begins.

The park office is located at the Paso de Cortés (Cortés’s Pass), named after the Spanish conquistador Hernán Cortés, who crossed it in 1519 after leaving Cholula, the nearby pre-Hispanic capital where he and his men had slaughtered between 5,000 and 6,000 people. Legend has it that, on the way, some of his men climbed Popo to collect sulfur for gunpowder for their canons and rifles. Then they descended into the Valley of Mexico to eventually conquer Tenochitlan, the island city that’s now the central part of Mexico City.

Yes, it’s a long story, and a fascinating one.

Today, a bumpy dirt road leads down the mountain slopes from the Paso de Cortes to Cholula, one of the most attractive towns in the area, with its yellow church built atop a massive, mostly unexcavated pyramid that resembles a hill. So, a nice two-day trip is an early morning hike in the national park, a twisty downhill drive to Cholula, and an evening and next morning exploring the town. You could also visit the city of Puebla right next to Cholula, making for a weekend of dramatic nature, pleasant towns, great food, and astounding history.

The Monarch Butterfly Migration to Mexico

If I told you that, every year, millions of insects migrate thousands of miles from the eastern U.S. and Canada to the same part of central Mexico, would you want to go there to see them? Probably not, if you’re imagining roaches or locusts or something similarly horrible.

Fortunately, the protagonist of this voyage is the monarch butterfly, pleasant creatures to walk among as they gather in great groups on the trunks of tall oyamel fir trees in the mountain forests of Michoacan and the State of Mexico.


This migration is one of the largest in the world, certainly the largest in North America, and the only one by insects that includes the return trip. And it happens right above our heads every year—millions of butterflies following no leader but instinct.

Or is it something more than instinct? It’s still a mystery to scientists how these masses of butterflies return to the same specific areas every year, a relatively small region of the central Mexican plateau that’s about a four-hour drive from Mexico City.

Although the precise method is unknown—it may have to do with Earth’s magnetic field, the wind currents of the northern hemisphere, or some kind of insect collective unconscious, the purpose is clear: escaping the cold winters of the north, which the butterflies are far too sensitive to survive, for the perpetual spring weather of the Mexican highlands, like so many other northern visitors. Much of the Mexican altiplano is arid and desert-like, but the areas around its mountain ranges have forest groves with enough humidity to support the needs of countless creatures, including the monarch butterfly.


Another mysterious phenomenon is involved in this migration: the birth of a special generation that lives much longer than the average butterfly. Most monarchs live only a few weeks, but in late summer, the migratory generation is born, the final generation of the year. Also called the Methusula generation, named after the biblical character who lived 969 years, these butterflies have a lifespan of up to nine months, allowing them to migrate south to Mexico, gather together in the trees for warmth and protection, breed and produce the next generation.

These successive generations have the typical two-to-five-week lifespan, so they fly north in stages, laying eggs and dying along the way. About four generations later, once the voyage is over, the migratory generation is born once again, destined to travel south like their great-great-great grandparents did the year before.


These insects face plenty of obstacles on the way, in both the north and south. For instance, according to the Washington Post, 20 million monarch butterflies die every year from getting hit by cars.

In the U.S. and Canada, the main threat comes from a decline in milkweed, which the butterflies rely on for food. More factory farms and fewer milkweed plants means less food for the monarchs. The butterflies also face danger from the weather—one harsh chill on the way, and an entire flock can be wiped out.


In Mexico, the greatest threat comes from habitat loss, especially logging, which is why the Mexican government has designated eight butterfly reserves. Five are open for limited tourism. You must stay on designated trails, and touching the butterflies is forbidden.

Besides being important sources of food for creatures higher on the food chain, monarch butterflies are important pollinators, like bees. Therefore, conservation efforts are underway in both countries. It’s such an important issue that the fate of monarch butterflies was a topic of discussion during a summit of North American leaders Barack Obama, Peña Nieto and Stephen Harper in 2014 in Toluca, the nearest big city to the reserves. Afterwards, Michelle Obama planted milkweed and other plants favored by monarchs at the White House.


I visited the largest reserve in Mexico, El Rosario, in March of 2019. We left early from Toluca, the capital of the State of Mexico, taking the highway west to the state of Michoacan. More remote parts of Michoacan have a bad reputation for danger from drug gangs, but there’s little to worry about on this well-worn route between the monarch butterfly reserves and Mexico City. (Toluca is on the way.)

Two hours into the drive, as we grew closer to the reserve, a few butterflies fluttered on the side of the twisting road, but nothing like the dense clouds we hoped to see. No matter, we pressed on, and after about three hours on a smooth highway surrounded by low brown hills, patches of rolling forest, and small concrete towns, we reached the parking lot for El Rosario.


First there was an uphill walk on a twisting path lined with wooden structures containing small restaurants and vendors, most selling butterfly-related souvenirs: painted ceramic decorations, tablecloths, and t-shirts, all decorated with the familiar orange and black pattern. Many had buckets of fresh fruit for sale, including peaches, strawberries, and blackberries bigger your thumb. Smoke poured from open grills in front of the restaurants, while teenagers holding laminated menus called out the specialties of each.


The entrance to the reserve appeared after this gauntlet, a wide arch above the crowds. By now the butterflies were thick in the air. We paid the 50-peso entrance fee (about $2.50 USD) and entered the reserve.


One long trail in a big loop went up and then down the mountain slope among the tall oyamel fir trees. A few other trails branched off from this loop, but they were either blocked off or for horses only. According to the guides selling horse rides, the butterflies were even thicker higher in the mountains and away from the crowds.

Some tree trunks were completely covered in butterflies, fluttering masses that resembled the leaves of dense creeper ivy in black and orange. The sky was full of them, the ground too, though mostly with corpses of the fallen. We passed several pools of muddy water where butterflies drank on the surface and from all sides.

The path took about two hours with slow walking and lots of stopping for pictures or to just take in the spectacle. With continuous walking, it would take about an hour. I couldn’t help but think that any other insect swarm might not be so pleasant, but the colorful butterflies instead made for a peaceful, beautiful sight. The light sound of fluttering wings was like a breeze through stiff leaves.

For the most part the butterflies stayed well above our heads, although regularly one or two would drift down to land on a shoulder or forearm. One of the park’s rules was to not touch any butterflies, and it seemed well respected for the most part. You had to watch your step as well, because many butterflies ended up landing on the path.


Once we left the park, we took a different route home, on narrow highways through the forested mountains of Michoacan to the magic town of El Oro, which translates to The Gold.

El Oro used to be a gold mining community that attracted prospectors from all over the world, especially from English companies, which is reflected today with names like Brockman for a large reservoir next to the town. Buildings like the Municipal Palace and the Juarez Theatre have art nouveau and neoclassical architecture that you don’t usually see in Mexican small towns, which are typically in the Spanish colonial style.


We ate lunch in the Vagon Express Minero restaurant inside an old converted train car in the center of town. When someone stood up or a waitress walked by, the whole car rocked back and forth with the motion. The food was ok; the atmosphere better.


I’d already been to Tlapujajua, another magic town just up the road, but never to El Oro itself. Both are nice and quite different—Tlapujajua is all winding cobblestone streets on the side of a mountain slope, while El Oro is relatively flat and laid out in a grid. Visiting both in one day would be easy, and would give a nice introduction to the tranquil, friendly Mexican magic towns.

The magic town designation is a program in Mexico to recognize and preserve the most beautiful and representative small towns in the country. At the moment there are 121. I’ve been to many—maybe 40 or 50—and each has something unique or interesting.

In El Oro, it’s certainly the ambiance, with qualities not seen elsewhere in Mexico—British names and wooden buildings, a train car restaurant, and an old train station across the street that’s now a museum. Besides the Tequila trains that leave from Guadalajara and the Copper Canyon train in the north, there are no passenger trains in Mexico, so these are rare sights.


Another good stop near the reserves is Valle de Bravo in the State of Mexico, which is in the opposite direction from El Oro and Tlapujajua. With its large reservoir for boat rides, tall mountains for parasailing or mountain biking, and pretty town center, Valle de Bravo is a popular weekend destination for people living in the madness of Mexico City. If you wanted to spend more than one day on your butterfly adventure, a small hotel in Valle de Bravo would be your best choice.

How to get there

Many websites offer tours to the butterfly reserves, some for thousands of U.S. dollars. Unless you’ve got the money and want a comprehensive scientific explanation of everything you’ll see, however, you don’t need a tour, especially considering the low entrance fees for the reserves. El Rosario was 50 pesos, about $2.50 USD, and I’m sure the other reserves have similar prices, if not the same.

All you need is a rental car and a GPS or a cell phone with the Waze app to help you navigate. The highways and roads are generally good but can become confusing once you leave the highway at Zitacuaro and pass through small towns on the way to the reserve. There aren’t many street signs in the towns—most are confusing grids of one-way streets, many with parked cars partially blocking the way. Here’s where you’ll need to follow Waze, or if there’s traffic, you can follow the cars in front of you—they’re probably going to the reserve.

The reserves are open from mid-November to March, with the best times for viewing butterflies from January to early March.

Travel in Costa Rica

I’d like to thank my favorite travel website Transitions Abroad for publishing my newest story Do It Yourself Travel in Costa Rica. Please click the link for the story and lots of photos. Below are some more.


Costa Rica was an easy trip from Mexico: After a few hours on a direct flight, we arrived in the capital San Jose, where we rented a car and drove all day to a hotel cabin outside Volcan Tenorio National Park, famous for the multicolored Rio Celeste.


National Parks were our priority in Costa Rica. Besides Tenorio, we also spent a day of hiking at the foot of another volcano, Arenal, and then spent several days at Manuel Antonio on the Pacific Ocean, stopping on the way at Carara National Park. All four were quite different: rainforests from distinct ecosystems, mountains or coast, and always lots of animals.


Below is a Capuchin monkey in Manuel Antonio National Park. We also saw squirrel monkeys, coati, agouti, deer, crocodiles, caimans, lots of lizards like iguanas and chameleons, countless birds, and a sloth. (Read about the sloth in the article.)


San Jose was an interesting place to walk around for a few hours before we returned the rental car and flew back to Mexico.


And yes, we did the zipline thing. This is supposedly the longest zipline in Central America, about 8/10 of a mile. Very fun and worthwhile.


Exploring Costa Rica by car and on foot was a fantastic trip for many reasons, especially for the nature. I hope to go back soon. Read more about it and get lots of advice in Do It Yourself Travel in Costa Rica.
