Select participants and date
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.

Adventure Tips
Wear water‑ready footwear
Choose shoes with good grip and drainage — you’ll move between wet boulders, river crossings and slick coastal limestone.
Bring a small dry bag
Protect electronics and dry a change of clothes for the return drive; a 5–10L bag is ideal.
Know your swim limits
Guides provide life vests but strong swimming and comfort in caves are required for certain sections and optional jumps.
Use reef‑ and freshwater‑safe sunscreen
Rinse off before entering freshwater pools and avoid chemical sunscreens that harm aquatic systems.
Local Insights
Wildlife

History
Cueva del Indio contains dozens of Taino petroglyphs; the cave and coastal platform were important ceremonial and observation sites before European contact.
Conservation
Guides emphasize minimal-impact practices — avoid touching petroglyphs, use reef/freshwater-safe products and pack out trash to protect fragile cave and river ecosystems.
