Chapultepec Forest: Mexico City's Green Heart

Chapultepec Forest covers roughly 686 hectares in the Miguel Hidalgo borough, making it more than twice the size of New York's Central Park. The park is free to enter and most of it stays open every day, though the main First Section closes on Mondays.

That Monday closure catches people off guard. I've watched families rattle the gates at the Paseo de la Reforma entrance around 9 a.m., only to find staff directing them toward the Second Section instead. If your itinerary has any flexibility, build your Chapultepec day around Tuesday through Sunday and treat Monday as a museum-and-markets day elsewhere in the city.

Sections, Hours, and How to Get There

The park is split into four sections, and they behave very differently. The First Section holds almost everything a first-time visitor wants: Chapultepec Castle, the National Museum of Anthropology, the zoo, the botanical garden, and the main lake. The Second and Third Sections are quieter, greener, and mostly local. The Fourth Section, opened in 2023, sits further west near Santa Fe and includes the new Cineteca Nacional.

Opening hours by section

The official schedule lists the First Section as open Tuesday to Sunday, 5:00 to 18:00, with no pets allowed. The Second and Third Sections stay open 24 hours, 365 days a year, and leashed dogs are welcome in the Second apart from the El Sope running track. The Fourth Section opens daily from 10:00 to 19:00. These hours hold on public holidays and school vacations, but they are subject to change — check the official Bosque de Chapultepec site before you go.

Individual venues inside the park run their own clocks. The zoo is free and opens Tuesday to Sunday, 9:00 to 17:00, closed Mondays plus January 1 and December 25. The National Museum of Anthropology opens Tuesday to Sunday, 9:00 to 18:00, and closes on Mondays. Chapultepec Castle (the National Museum of History) also closes Mondays, 9:00 to 17:00 the rest of the week.

Metro, Metrobús, and Cablebús

Metro Line 1 drops you at Chapultepec station directly across from the First Section's main gate. Line 7 serves Auditorio, which puts you closest to the anthropology museum and the castle path, and Constituyentes, which feeds into the Second Section. Metrobús Line 7 stops at Chapultepec, Gandhi, and Antropología. The Cablebús Line 3 connects to Los Pinos station on the eastern edge of the First Section and runs Monday to Friday from 5:00 to 23:00, Saturday from 6:00, and Sunday from 7:00.

My own habit: arrive via Auditorio on a weekday morning, walk the castle first before the queues form, then drift downhill toward the anthropology museum. By the time you exit, the food stalls along the lake are open and the crowds have thinned from their late-morning peak.

What to See and How Long It Takes

A fast loop of the First Section takes about three hours. Doing a museum properly plus the castle adds another half day. I've met travelers who spent an entire week in Chapultepec across repeat visits, and I don't think they were exaggerating.

The First Section essentials

Chapultepec Castle sits at the top of the hill and offers the best panoramic view of the city you'll get without a drone. The walk up is shaded and takes 15 to 20 minutes at an easy pace. The National Museum of Anthropology next door is genuinely one of the great museums of the Americas, with the Aztec Sun Stone as its centerpiece, and 90 minutes is the bare minimum I'd give it. The zoo's axolotl exhibit alone justifies the free entry.

Lago Mayor anchors the weekend scene. Rowboats rent by the hour, and the surrounding path is flat enough for strollers and wheelchairs. The Jardín Botánico, entered from Paseo de la Reforma, opens Tuesday to Sunday, 9:00 to 16:00, and costs nothing.

Beyond the First Section

Sections Two and Three reward people who've already ticked off the castle. The Second has the Museo de Historia Natural, the Aztlán amusement park, and the Dolores reservoir. The Third is where the forest actually feels like forest — trails, fewer vendors, and cyclists on the main paths. Stick to marked routes and go in daylight. Sundown in the Third Section is not the moment to test your sense of direction.

Ticket costs in 2026

Entry to the forest is free. Museums are not. As of January 2026, INAH-run sites including the anthropology museum and Chapultepec Castle charge 210 pesos for foreign visitors and 105 pesos for Mexican nationals and residents with ID. Sundays remain free for Mexican citizens and residents only. Private museums run differently: the Museo Tamayo and Museo de Arte Moderno charge 95 pesos, and the Papalote children's museum charges 220 pesos with some experiences priced separately. Fees are subject to change — check the official site for current rates.

When to Go and What to Expect

Mexico City's dry season runs roughly November through May, and that's the window I'd pick. March, April, and May bring the clearest skies and the warmest afternoons, with highs around 25°C. The rainy season from June to September means afternoon downpours that flood paths and empty the park fast. September is the wettest month, with around 183 mm of rain.

Weekday mornings are your friend. By 10:00 on a Saturday, the lake edge is a wall of picnic blankets and elote carts, and the castle ticket line stretches down the hill. Sunday transforms the park into the city's living room — free museum entry for locals, pony rides, vendors everywhere. It's a fantastic cultural experience and a terrible time to see anything efficiently. Pick one.

Comfortable shoes matter more than you think. Exploring the First Section on foot typically covers 5 to 8 kilometers, and the hill to the castle is steep in places. Bring water; the vendors inside charge tourist prices.

Is Chapultepec Forest open on Mondays?

The First Section is closed on Mondays. The Second and Third Sections remain open 24 hours, and the Fourth Section opens daily from 10:00 to 19:00. Most museums inside the park also close on Mondays, so plan a Monday visit around the quieter sections or skip the park entirely.

How do I get to Chapultepec Forest by public transport?

Take Metro Line 1 to Chapultepec station for the First Section's main gate, or Line 7 to Auditorio for the anthropology museum and castle. Metrobús Line 7 stops at Chapultepec, Gandhi, and Antropología. A taxi from the Zócalo takes about 6 minutes outside rush hour.

How much time should I budget for Chapultepec?

A quick walk through the First Section takes about three hours. Add the castle and one major museum and you're at a full day. Sections Two and Three are worth a half day each if you want to escape the tourist core.
