When the sun slides beneath the mangrove canopy at Laguna Grande, the water starts to remember light in a way that feels like astonishment made visible. Paddlers push off from a small sandy launch and move silently between roots and reflection, the mangroves leaning close as if to listen. With each stroke the kayak cuts a neon path: tiny organisms flare where the hull disturbs the surface, and the bay answers with a slow, living glow.
