You step off the bus into humid forest; the air smells of wet earth and hot mineral vents. The trail pushes forward beneath a roof of heliconia and cecropia, and the Celeste River appears like a painted ribbon — bright turquoise where sunlight hits suspended minerals and pale where steam gathers. The river dares you closer, steam rising from thermal pools and mud pots that bubble like a simmering kettle.
