The last streaks of daylight fade over Puntarenas, that long, narrow strip of land that stretches into the Gulf of Nicoya like a finger pointing to the horizon. Streetlights hum to life along the Paseo de los Turistas, the scent of grilled fish drifts from seaside sodas, and the port’s daytime clatter melts into the lazy rhythm of a coastal evening. But beyond the laughter and music, just past the glow of town, a darker, quieter world is waiting — the mangroves.
The boat rocks gently as you step in, the water already inky and still. A silver moon, swollen and bright, hangs low, turning the channels into liquid mirrors. The motor hums softly, then dies, replaced by the sound of oars dipping into water. The air is thick with the scent of salt and earth, the kind that clings to your skin. Shadows loom on either side — tangled roots and gnarled trunks that look like they could lift themselves from the water and walk.

Somewhere in the distance, a heron lets out a sharp, almost scolding call. Then, the magic begins. A torch beam slices through the dark, catching a sudden glimmer — two red pinpricks in the black, unblinking. Crocodile. Your guide smiles, as if this is nothing unusual, and it isn’t. Not here. Not in a place where the night belongs to creatures most of us only read about.
Bats flicker overhead like scraps of paper caught in a breeze. Tiny fish ripple under the boat, and now and then, a flash of silver arcs through the air, as if leaping for the moon itself. On certain nights, the water stirs with sparks — bioluminescent plankton lighting up like underwater stars when disturbed, turning every oar stroke into a galaxy in motion.
Your guide begins to tell a story — one you’ve never heard before. It’s about a fisherman who followed a glowing light deep into these mangroves and never came back. Some say it was the lantern of a ghost ship captain, forever searching for a crew. Others say it was just fireflies reflecting on the tide. You’d like to believe the first version. It feels right in a place like this.
And yet, there’s no fear — only the quiet thrill of being somewhere untouched, somewhere that hasn’t changed in decades. This is where Costa Rica keeps its secrets. Where the country’s culture is more than fiestas and beaches; it’s here, in the whispered legends passed down through generations, told under the cover of night.
When you return to shore, the town feels almost too bright, too noisy. You can still hear the soft lap of water against roots, still see those red eyes in the dark. You realise that while you came for an adventure, what you found was something richer — a connection to the wild heart of Puntarenas, beating softly under the moon.
