Canon del Sumidero from the Water and the Arbol de Navidad

Open lanchas leave the pier at Chiapa de Corzo and run 35 km downstream through canyon walls exceeding 1,000 m, turning back at the Chicoasen dam; shooting from the boat means working with a moving, low platform rather than a fixed frame, so foreground is the boat's gunwale and background is the canyon wall sliding past. The Arbol de Navidad, a moss-covered travertine formation shaped like a fir tree, is the set-piece subject and only carries a proper flow of water in and just after the rainy season; it cannot be reached by road, so the boat is the only vantage point. Seats on the right-hand side going downstream give the better angle on the formation. Morning departures from 08:00 find the water glassy and the canyon walls still shaded, producing calmer reflections, while the Arbol de Navidad itself is best lit in the late morning once direct sun reaches the far bank. July to November is when water actually flows over the Arbol de Navidad; December to April brings clearer skies and calmer water but a much thinner cascade. Boats depart once full rather than on a fixed schedule, generally between 08:00 and 16:00, and there is no fixed queue for seating beyond claiming a position as the boat fills, so early arrival at the pier secures the favoured right-hand seats. Tripods are impractical from a moving boat; no permit or fee applies beyond the standard fare of about 250-300 MXN (approx USD 15-18) per person for the two-hour round trip, cash in pesos.
