Every November, tens of millions of monarch butterflies fly up to 4,000 km from Canada and the United States to a handful of fir-covered mountaintops west of Mexico City, and hang there in clusters so dense the branches bend. The Monarch Butterfly Biosphere Reserve is the most famous of Mexico’s protected areas, and it sums up the country’s parks well: the big draw is often a season, not a view.
Mexico has some 70 national parks and around 45 biosphere reserves, and the reserves are usually the better trip. Gray whales calve in the lagoons of the El Vizcaíno sanctuary in Baja from January to March; flamingos crowd the estuary at Celestún; and the mangroves and lagoons of Sian Ka’an start a short drive south of Tulum.
The landscapes are just as big. The Copper Canyon system in Chihuahua is deeper in places than the Grand Canyon, the walls of the Sumidero Canyon rise about 1,000 m above a river you ride by boat, and a chain of volcanoes crosses the middle of the country, from Nevado de Toluca to Pico de Orizaba, the highest peak in Mexico.
At a Glance#
- The one to plan around: the Monarch Butterfly Biosphere Reserve, from mid-November to March, about three to four hours from Mexico City.
- Canyons: the Copper Canyon by the Chepe train, with Basaseachic Falls nearby, and the boat trip through Sumidero Canyon in Chiapas.
- Whales and sea life: gray whales at El Vizcaíno near Guerrero Negro, sea lions at Isla Espíritu Santo off La Paz, giant mantas at the Revillagigedo Islands and whale sharks off Holbox.
- Volcanoes: Iztaccíhuatl and Popocatépetl from Paso de Cortés, the crater lakes of Nevado de Toluca, La Malinche and Pico de Orizaba.
- Yucatán wetlands: Sian Ka’an south of Tulum and the flamingos of Celestún.
- Deserts and the north: the craters and dunes of El Pinacate in Sonora, Cumbres de Monterrey and the dawn bird flight at the Cave of Swallows.
- Best season: November to April for almost everything; summer rains turn the waterfalls on but close some high trails.
Monarch Butterfly Biosphere Reserve#
The Monarch Butterfly Biosphere Reserve covers the high oyamel fir forests on the border of Michoacán and the State of Mexico, at about 3,000 m. The butterflies arrive from late October and early November, settle in their colonies by December and stay until about mid-March, when they mate and head north. The best weeks are late January and February: the colonies are at full size, and on a warm, sunny day they lift off the trees by the thousand around midday and fill the air. On a cold, cloudy morning they stay clustered and still, so plan a spare day if you can.
Only a few sanctuaries are open to visitors. El Rosario, near Angangueo and Ocampo in Michoacán, is the largest and most visited, with a steep climb of roughly an hour from the car park. Sierra Chincua, also near Angangueo, has a gentler trail. Piedra Herrada, in the State of Mexico near Valle de Bravo, is the closest to the capital at around 2.5 to 3 hours by road and the easiest day trip. You walk or ride a hired horse up the trail, then a local guide leads you to the colony and keeps the group quiet behind a rope. Each sanctuary charges a modest entry fee, and guides and horses are paid separately.
Most visitors come on a tour from Mexico City, a long day of six to eight hours on the road. Staying in Angangueo, Zitácuaro or Valle de Bravo lets you be at the gate at opening, before the crowds. See our safety guide for the current advisory on Michoacán before you choose a sanctuary.
The volcano parks#
The Trans-Mexican Volcanic Belt crosses the country just south of Mexico City, and several of its peaks sit inside national parks you can reach in a day. The classic is Paso de Cortés, the 3,600 m saddle between Iztaccíhuatl (about 5,230 m) and Popocatépetl (about 5,400 m), reached by road from Amecameca. Popocatépetl is one of the most active volcanoes in North America and climbing it is banned; you see it smoking from the pass. Iztaccíhuatl, the “sleeping woman”, is the hiking volcano: trails start at La Joya, a short drive beyond the pass, and fit climbers attempt the summit in a long day with a guide. Register and pay the park fee at the Paso de Cortés visitor centre.
Nevado de Toluca, an hour from Toluca, is the easiest high crater in Mexico: a road climbs to the Parque de los Venados, where private cars must stop, and from there you walk or cycle up to the crater and down to the Sol and Luna lakes inside it. The crater is closed at times for bad weather. La Malinche in Tlaxcala is the standard acclimatisation hike, a non-technical climb to about 4,460 m from the cabins at its base. Pico de Orizaba, at about 5,600 m the third-highest mountain in North America, is a glaciated climb from Tlachichuca for experienced mountaineers between November and March.

Closer to the city, the Desierto de los Leones park has forest trails around a 17th-century Carmelite convent, and the lakes of Lagunas de Zempoala sit in pine forest on the road to Cuernavaca. Both are weekend escapes for Mexico City families, quiet on weekdays.
Altitude and volcano alerts
Paso de Cortés, Nevado de Toluca and La Malinche all start well above 3,000 m. Spend two or three days in Mexico City first, walk slowly and turn back if you get a bad headache. Access to Popocatépetl’s slopes depends on the volcano’s alert level, which can close roads around it at short notice.
Copper Canyon#
The Copper Canyon, Barrancas del Cobre in Spanish, is a network of six main canyons in the Sierra Tarahumara of Chihuahua, several of them deeper than the Grand Canyon. It is home to the Rarámuri, and the way most people see it is from the Chepe railway, which runs about 650 km between the plains of Chihuahua and the Pacific at Los Mochis, through 86 tunnels and over 37 bridges. The faster, more comfortable Chepe Express covers the most scenic section, between Creel and Los Mochis; the Chepe Regional runs the whole line.
Break the journey rather than riding straight through. Creel is the main base, a timber town with tours to the Rarámuri villages, Lake Arareco and the Valley of the Monks. Divisadero is the classic viewpoint over three canyons at once, and the adjoining Barrancas del Cobre Adventure Park has a cable car and some of the longest ziplines in the world. Urique, at the bottom of the deepest canyon, is a long, hair-raising drive down but the most rewarding stop for hikers. Plan three to five days.
Basaseachic Falls, about three hours north of Creel, drops some 246 m in one leap, the highest permanent waterfall in Mexico. It flows strongest from July to September, after the rains, and the walk from the rim to the base takes an hour or two each way. Book Chepe Express seats well ahead for Easter and Christmas, and check current conditions in the Sierra Tarahumara in our safety guide.

Sumidero Canyon and Chiapas#
Sumidero Canyon National Park is the easiest big canyon in Mexico to see: launches leave from Chiapa de Corzo and from the Cahuaré jetty near Tuxtla Gutiérrez for a trip of about two hours up the Grijalva River, between walls that rise around 1,000 m. On the way you usually see crocodiles basking on the banks, spider monkeys, herons and the moss-covered “Christmas tree” rock formation where a waterfall runs in the wet season. A road along the rim from Tuxtla has five viewpoints over the canyon; a taxi or tour can do both the boat and the viewpoints in a day.
Chiapas also has the country’s best jungle. The Lacandon rainforest along the Guatemalan border protects the ruins of Yaxchilán and Bonampak, and the tour from Palenque that visits them includes a boat ride on the Usumacinta River. Near the Guatemalan border, Lagunas de Montebello National Park has dozens of lakes in shades of blue and green, a long day trip from San Cristóbal de las Casas that can include the ruins of Chinkultic. The waterfalls of Agua Azul and Misol-Ha are usually visited on the road between San Cristóbal and Palenque, at their bluest from March to May before the rains turn them muddy. For the ruins, see our historic sites guide.
Yucatán and the Caribbean#
Sian Ka’an, a UNESCO World Heritage biosphere reserve covering more than 5,000 square km south of Tulum, is a mix of lagoons, mangrove channels, savannah, jungle and reef. Most visitors take a boat tour, either from Punta Allen at the end of the bumpy sand road down the coast, for dolphins, turtles and fly-fishing flats, or from the Muyil side, where you float down an ancient Maya canal through the mangroves in a life jacket. Pay the reserve fee at the entrance checkpoint, and go with a local cooperative guide.
On the Gulf side, the estuary at Celestún, about 90 minutes from Mérida, is the easiest place to see American flamingos: boats leave from the beach and the bridge, with the largest flocks from about November to March. The Ría Lagartos reserve on the north coast has even bigger breeding colonies and the pink salt ponds of Las Coloradas. Off the Caribbean coast, Holbox is the base for swimming with whale sharks from about June to September, and Isla Contoy, a bird sanctuary north of Isla Mujeres, takes a limited number of visitors a day on licensed boats. For the Yucatán’s beaches and cenotes, see our beaches guide.
Baja California and the Gulf of California#
The Whale Sanctuary of El Vizcaíno protects the lagoons where Pacific gray whales mate and give birth each winter, after swimming down from the Arctic. At Laguna Ojo de Liebre, just outside Guerrero Negro, and at San Ignacio Lagoon further south, licensed pangas take small groups out among the whales, and mothers often bring their calves right up to the boat to be touched. The season runs from about mid-December to April, with the most calves in February and March. Bahía Magdalena, reached from Puerto López Mateos, is closer to La Paz and Los Cabos.

The islands and protected areas of the Gulf of California are a World Heritage site of desert islands and rich water. From La Paz, day boats run to Isla Espíritu Santo, with red cliffs, empty beaches and a sea lion colony at Los Islotes you can snorkel with; La Paz bay also has whale sharks from about October to April. Cabo Pulmo National Park, north of San José del Cabo, has the healthiest reef in the gulf after a fishing ban brought it back. Far out in the Pacific, the Revillagigedo Islands are reached only by liveaboard dive boats from Cabo San Lucas, a crossing of about a day, for giant mantas, dolphins and sharks between November and May.
The Pacific coast and the north#
Off Punta Mita, north of Puerto Vallarta, Islas Marietas National Park is famous for its Hidden Beach, a crater-like beach open to the sky that you reach by swimming through a short tunnel. Visits are capped and only licensed operators can land there, so book a permitted tour rather than buying from a beach tout; many trips only snorkel nearby. On the Oaxaca coast west of Puerto Escondido, Lagunas de Chacahua is a sleepy park of mangrove lagoons and a long surf beach, reached by boat from Zapotalito.
In the northwest, El Pinacate y Gran Desierto de Altar in Sonora is a World Heritage landscape of black lava fields, giant round craters such as El Elegante and the largest field of active sand dunes in North America. It is a couple of hours’ drive from Puerto Peñasco; register at the visitor centre, carry plenty of water and avoid the summer heat. Above Monterrey, Cumbres de Monterrey National Park has the Cola de Caballo waterfall and the limestone walls of Cañón La Huasteca, popular with climbers.
In San Luis Potosí, the Cave of Swallows is a sinkhole about 370 m deep. At dawn, thousands of swifts and parakeets spiral up out of it, and at dusk they dive back in. It anchors a trip to the Huasteca Potosina, a region of turquoise rivers and waterfalls such as Tamul.

How to visit#
Mexico’s parks and reserves are run by CONANP, the national protected areas commission, and most charge a daily conservation fee paid at the gate or included in a tour price, often in the form of a wristband. Facilities are basic by US or European standards: expect a gate, a car park and perhaps a small visitor centre, with few marked trails beyond the main routes. In many places, including the monarch sanctuaries, Sumidero and the whale lagoons, the land or the boats belong to local ejidos and cooperatives, and hiring their guides is required or simply the way things work.
A car makes Baja, the volcano parks and the Yucatán much easier, but drive in daylight and stick to toll roads where you can; our getting around guide covers car hire and buses. Tours from Mexico City, Tulum, La Paz and Tuxtla are good value for the harder trips. Bring cash in pesos for fees, guides and boats, because card machines are rare at park gates.
The dry season, from November to April, is the best time for almost every park, and it lines up with the butterflies, whales and flamingos. The rainy season, from June to October, fills the waterfalls and turns the forests green, but brings afternoon storms, hurricane risk on the coasts and muddy roads. See our best time to visit guide for month-by-month weather.
Wildlife seasons are short and fixed, so build your route around them: monarchs and gray whales overlap in February, which makes a trip that combines Mexico City with Baja California Sur easy to plan.
Rules are simple and enforced by guides: stay on the trail and behind the ropes at the monarch colonies, keep quiet and do not touch the butterflies, never chase or crowd whales or whale sharks, and use reef-safe sunscreen or none in marine parks, where some operators ask you to wear a rash vest instead. Drones need a permit in protected areas.

Mexico national parks FAQs#
What is the most famous national park in Mexico?
The Monarch Butterfly Biosphere Reserve is the best known, followed by the Copper Canyon and Sumidero Canyon. For marine life, the whale lagoons of El Vizcaíno and the islands of the Gulf of California are as famous as any land park.
When can you see the monarch butterflies in Mexico?
The butterflies are in the sanctuaries from about November to mid-March. The best time is late January and February, on a sunny day around midday, when the colonies are at their largest and most active.
Can you visit the monarch butterflies as a day trip from Mexico City?
Yes. Piedra Herrada near Valle de Bravo is about 2.5 to 3 hours away and is the easiest day trip; El Rosario and Sierra Chincua take longer. Tours leave Mexico City early in the morning and return in the evening.
When is whale watching season in Baja California?
Gray whales are in the Baja lagoons from about mid-December to April, with the most mothers and calves in February and March. Humpbacks pass Los Cabos and Puerto Vallarta from about December to March.
How long does the Copper Canyon train take?
The full Chepe line between Chihuahua and Los Mochis takes most of a day without stops. Most people ride the scenic section between Creel and Los Mochis on the Chepe Express and break the trip for a night or two at Creel or Divisadero.
Can you climb Popocatépetl?
No. Popocatépetl is an active volcano and climbing it is banned. You can see it from Paso de Cortés and hike or climb its neighbour Iztaccíhuatl instead, ideally with a guide.
Do I need a guide in Mexican national parks?
For the monarch sanctuaries, the whale lagoons, Sumidero Canyon and Sian Ka’an’s boat tours, yes, because access is through local guides and licensed boats. For the volcano parks and easier trails near Mexico City you can go alone, though a guide is wise above 4,000 m.
What is the best time to visit Mexico's national parks?
November to April, the dry season, is best for most parks and for the butterflies, whales and flamingos. The summer rainy season is good for waterfalls such as Basaseachic but brings storms and muddy roads.
