Diving Punta Sur & the Devil's Throat
Coral towers and chimneys pierced by tunnels and caverns. The signature feature is the Devil's Throat — a narrow chimney that drops through the coral and opens deep on the wall, reaching roughly 28–40 m across the swim-through.
It is an overhead environment with no direct ascent, at depths where gas planning and steady buoyancy matter. We dive it only with experienced advanced divers.
If it is not the right fit on the day — for your experience or the conditions — we will say so and pick another site.
