Once called La Presa del Muerto, this 48-hectare wetland shelters migratory white pelicans, holds protected status since 2009, and costs nothing to enter.
Locals still call it La Presa del Muerto — the Dead Man's Reservoir. That grim nickname belongs to Parque Espejo de los Lirios, a 48-hectare wetland park in Cuautitlán Izcalli, México, where still water once hid the bodies of murdered landowners and now reflects migrating white pelicans against an open sky. The official name translates as Mirror of the Lilies, but the old one tells you more about what this place has survived.
The park sits at the intersection of Avenida El Jacal and Avenida Constitución, covering 487,000 square meters — an area the size of 68 football pitches carved out of Mexico City's northern sprawl. At its center, a 14-hectare artificial lake fed by a canal from the Presa de Guadalupe drops to depths beyond 2.5 meters.
A 2-kilometer clay running track circles the water, and the perimeter fills with basketball courts, football fields, cycling paths, and family palapas with grills. But the draw isn't the infrastructure. It's the unlikely survival of open water and wetland in a metropolitan zone of over 22 million people, and the birds that figured this out before the guidebooks did.
The park opens daily at 6 AM and closes at 6 PM. Entry is free. Pets are not allowed — a rule that, given the resident birdlife, makes sense.
History
Before Cuautitlán Izcalli existed as a municipality — it was formally created in 1973 — the body of water at its heart served as a cattle watering hole. No one built it for recreation or conservation. It was functional, rural, and largely ignored by anyone who didn't own livestock.
What happened between the ranching era and the park's current incarnation as a protected natural area involves murder, bureaucratic failure, and one politician's attempt to fix a promise that had rusted for sixteen years.
The turning point
On December 17, 2009, the Gaceta Municipal of Cuautitlán Izcalli published a decree that should have changed everything. The park was officially designated an Área Natural Protegida — a legally protected natural area — with prohibitions on land-use change and criminal penalties for violations. The decree was precise: 487,407.31 square meters of wetland, pinned to two named avenues, shielded by law.
Then nothing happened. The Plan de Manejo — the management plan required by law to give the decree teeth — was never written. For sixteen years, the park held protected status on paper while receiving no corresponding protection on the ground. Local media would later describe the situation as una promesa oxidada — a rusty promise.
On September 26, 2025, municipal president Daniel Serrano formally re-declared the park's protected status and announced a full rehabilitation program. The city council finally approved the long-overdue management plan. Serrano's announcement was, in effect, an admission: the 2009 decree had been ignored by every administration that followed it. Whether this attempt proves different remains the park's open question.
Yes, especially if you're already in northern Estado de México — it's free, nearly 49 hectares (roughly 68 soccer fields), and genuinely peaceful for a municipal park. The 14-hectare lake is the draw: still water that reflects the sky and, in winter, attracts migratory white pelicans that locals describe as an emotional sight.
One to two hours covers a full loop of the 2-kilometer clay track around the lake with time to watch the birds. Families with children tend to stay longer given the cycling paths, mechanical rides, horse rides, and basketball courts on site.
No — pets are not permitted. The restriction is consistent with the park's Área Natural Protegida status, which prohibits activities that disturb the wetland and its resident wildlife.
White pelicans have used the lake as a migratory refuge since at least February 2004. They typically arrive in winter months; checking the Gobierno de Izcalli Facebook page close to your visit is the most reliable way to confirm current sightings.
Take the Tren Suburbano to Lechería station, then catch a micro toward the park — ask the driver for "Espejo de los Lirios" — or take one toward the Palacio Municipal de Izcalli and a short taxi from there. The entrance is at Av. El Jacal and Av. Constitución.
Entry to the park is free. Paid parking is available on Av. El Jacal and Av. Constitución for visitors arriving by car. Individual activities like horse rides and mechanical rides may carry their own fees, though these are not confirmed in official sources.
The lake was historically called "La Presa del Muerto" — The Dead Man's Reservoir — a name tied to oral accounts of land dispute murders, with bodies allegedly dumped in the water. The area became a public park in 1973 and was formally declared a protected natural area in December 2009, though the legally required management plan went unwritten for sixteen years until the city council finally approved it in late 2025.
The park has a 2-kilometer clay running track, cycling paths including a children's circuit, basketball courts, football fields, a swimming pool, horse rides, family palapas with grills, and a small tourist bus called the Izcalli Bus. A cultural walkway — the Paseo Cultural Juan Pablo II, established in 2006 — runs through the grounds with a statue of Pope John Paul II.
