You step off the shaded coastal road and the Atlantic wind immediately rearranges your hair and your plans. Ahead, the 7 arches — a battered limestone bridge scored by waves — curve like a natural colonnade framing the sea. Beneath your boots the rock smells of salt and age; above, gulls wheel and claim the skyline. This is Cueva del Indio, where you begin the day tracing the shoreline to a Taino cave whose walls still hold hand-carved petroglyphs that point back to a pre‑Columbian Puerto Rico.
