Every guidebook points you to the same three beaches. Nobody hands you a map to the ponds.
They sit behind old lava flows, fed by fresh water pushing up through the rock, calm enough to mirror the palms standing over them. No waves. No crowds. Just still water, black rock, and the kind of quiet you don't get anywhere near a resort.
You find them the same way most people who actually live here found them — someone tells you, or you go looking on a day you didn't have anywhere else to be.
That's part of what separates visiting the island from living on it. The beaches are for everyone. The ponds are for the people who slowed down enough to notice they were there.
If you're planning a trip, don't just chase the postcard spots. Ask a local where the water's still. That question alone will take you somewhere the tour buses never go.
