Boca de Túnel Hanging Bridges

The Parque Ecoturístico Boca de Túnel lies roughly 15 kilometres from Calvillo in the Sierra del Laurel, in the south-western corner of Aguascalientes, Mexico, where the Presa de los Alamitos backs up into a narrow rock canyon. The park's defining feature is a circuit of hanging footbridges, thirteen in the commonly cited count, strung between the canyon walls above the water, supplemented by zip lines, rappel points and a set of shoreline paths. Two frames dominate the location. The first is from the bridges themselves, looking straight down the canyon along the line of cable and timber decking, with the reservoir below and the forested walls converging toward the dam mouth that gives the park its name. The second is from the shore looking up, where a person crossing a bridge provides scale against the rock face, which is the shot that makes the place legible. Because the canyon is deep and narrow, light is the constraint: the sun only reaches the water for a few hours either side of midday, and outside that window the gorge sits in flat shade while the rim above remains bright, a contrast range that is difficult to hold. Midday, unusual for landscape work, is therefore genuinely the best time here. The dry season from October to May brings clearer water and firmer trails; the summer rains raise the reservoir, cloud the water and make the rock and decking slippery. Access is by a partly unpaved road from Calvillo and the park charges a modest entrance fee, typically a few tens of pesos per person, with the zip line and rappel activities priced separately; opening is generally daytime hours with weekend operation most reliable, and hours are worth confirming with the park before travelling. Tripods are impractical on the bridges, which move underfoot and are shared with other visitors, so handheld work with a fast shutter is the realistic approach. Spray and humidity near the water justify a rain cover. Drone flight should be cleared with park staff.
