Parque Nacional Nevado de Toluca

Parque Nacional Nevado de Toluca protects the extinct Xinantécatl volcano, Mexico's fourth-highest peak, whose collapsed crater holds two turquoise crater lakes, Laguna del Sol and Laguna de la Luna, at an elevation of roughly 4,200 meters. Visitors typically drive to the Parque de los Venados hut at about 4,050 meters, then hike the marked trail into the crater to reach the lakeshores, a round trip of three to five hours depending on fitness and altitude acclimatization. The high-altitude terrain shifts from pine and pine-oak forest on the lower slopes to open alpine grassland and bare volcanic rock near the crater rim, with the lakes themselves framed by the crater's jagged walls -- the classic photo vantage point is the rim trail looking down over both lakes together. Because the park sits above 3,500 meters for most of its accessible area, altitude sickness is a real risk for visitors arriving directly from lower elevations, and weather can turn quickly from clear skies to fog, wind, or snow even outside winter. Access to the crater itself has been intermittently restricted by CONANP for safety and environmental-recovery reasons in recent years, so visitors should confirm current conditions before making the trip. The park is busiest on weekends during the dry season from November through April, when clear mornings offer the best lake visibility before afternoon cloud cover typically rolls in.
