Boca del Diablo
A sea blowhole on the Samaná coast where swell forces spray through a rock opening.

On the exposed northern coast of the Samaná peninsula, swell drives into a cave under the rock and forces water and air out through an opening in the shelf above, sending spray several metres up when the sea is running. On calm days it does very little. The rock around it is sharp and unfenced and the surge is unpredictable. A rough track leaves the Las Galeras road and ends near the shelf.
What you actually see
- The blowhole - spray forced up through the rock when swell drives into the cave below.
- The rock shelf - the sharp limestone platform the opening sits in.
- The exposed coast - the northern shore of the peninsula facing open ocean.
- The surge - the unpredictable pulses of water coming through.
When to go
December to April has the northern swell that makes it work. On flat days there is nothing to see. Winter storms give the strongest effect.
Honest expectations
With no swell there is nothing happening at all. The rock is unfenced and people have been swept off similar shelves; standing close is genuinely dangerous. The access track is rough.
Nearby
Las Galeras is east, and Playa El Valle is west.
