A short descent from the Paso Ancho parking area leads down stone steps into a limestone gorge where the Río Tamasopo has carved a natural rock bridge and cavern, with a series of turquoise swimming pools and a waterfall pouring through the cave mouth.
The trailhead for Puente de Dios sits at a signed parking area off the unpaved access road that branches from the Tamasopo-Rioverde highway near the Paso Ancho turnoff, about 15 minutes by car from Tamasopo town; visitors pay a small parking fee at the lot before continuing on foot. From the entrance booth, a stone staircase of roughly 800 meters descends about 40 meters through dry tropical forest into a limestone gorge carved by the Río Tamasopo. The path is largely stepped and shaded by jungle canopy for the first stretch, opening onto exposed rock ledges as it nears the river. Footing changes from concrete and stone steps to wet, algae-slicked limestone close to the water, so grip matters more than speed. The route passes a mirador partway down with a first view over the turquoise pools before continuing to the natural rock bridge itself, where the river has bored a tunnel through the cliff and a waterfall drops through the cave mouth into a plunge pool. Most visitors turn around at this main pool, since the passage beyond into the cave interior involves swimming through partially submerged sections and is not part of the maintained walking trail. There is no drinking water or refuge hut along the descent; all supplies should be carried down from the entrance, where changing rooms, bathrooms and life-jacket rental are available. The site is prone to closure after heavy rain, when the river rises and turns brown, so conditions should be checked in advance during the June-to-September wet season. Overall the walk itself is short and moderate in grade, but the wet limestone near the pools demands careful footing, and the return climb back up the stone staircase in humid heat is the main physical challenge of the outing.
