Nevado de Toluca Crater Lakes Trail (Laguna del Sol y Laguna de la Luna)

The crater lakes trail begins at the same Parque de los Venados trailhead used for the Pico del Fraile route, inside the Nevado de Toluca Flora and Fauna Protection Area, reached by private vehicle or taxi from Toluca; the paved approach road has had seasonal closures since December 2025, so access should be confirmed before departure. From the trailhead near 3,600m, the marked path covers approximately 8.5km round trip with 500-600m of cumulative elevation gain to viewpoints on the crater rim above Laguna del Sol and Laguna de la Luna, the two glacial lakes sitting at 4,209m and 4,216m inside the extinct Xinantecatl volcano. The route climbs through pine forest for its lower half, offering intermittent shade, before opening onto exposed volcanic terrain of packed dirt and loose rock as it nears the rim; unlike the adjacent summit route, this trail does not require technical scrambling, though the thin air and loose footing near the top still demand caution. Notable landmarks include the treeline boundary, the first clear view of Laguna del Sol from the rim path, and the saddle between the two lakes where both bodies of water are visible together; this saddle makes a natural turn-around point for hikers not continuing toward the summit ridge. There are no refuge huts, food concessions, or water sources beyond the Parque de los Venados entrance, so 2-3 litres of water per person should be carried for the full round trip. Because the lakes sit above 4,200m, altitude acclimatization in Toluca for a day or two beforehand is advised, and the reflective volcanic terrain combined with intense high-altitude sun makes sunglasses and sun protection essential even on cool days.
