Sapodilla Hill is a limestone ridge on the southwest tip of Providenciales, near Chalk Sound. Its flat rock faces are covered with carvings left by sailors from the 17th to 19th centuries — names, ship names, dates, and elaborate pictures carved into the stone during stopovers. The earliest dated inscription is from the late 1600s; many are from the 1700s and early 1800s, the peak of the island's use as a waypoint for ships working the Caribbean.
The hill is a short climb from the road — fifteen minutes to the summit, which offers good views over Chalk Sound and the south coast. The carvings are scattered across several rock faces near the top; some are faded but still legible, others are remarkably crisp. The site is unguarded and freely accessible; the carvings are the kind of thing you can touch but should not.
