You step from the humid rainforest into a crest of spray and color — the waterfall hits you before you see it, a rushing curtain of impossible turquoise plunging into a calm pool. The river seems to dare you closer, its hue stealing the light and making the surrounding greens feel sharper. A guide points out Los Teñideros, the confluence where two streams mix and volcanic minerals react, producing the river’s surreal blue.
