Boka Pistol

Boca Pistol, Curaçao

One of the spectacular bokas or narrow inlets. As the wave reaches it, it shoots the water backward in the air with a great force, resembling a powerful blowhole.

Watamula Hole

Large window – opening down to the sea, located at the northern shore of the island. This is a former blowhole that now for most of the time is too large to create spectacular fountains. During stronger winds and the right direction of the wind, there still are observed nice spouts from Watamula Hole. There are though smaller blowholes to the north-east from Watamula hole and further, around the famous “bokas” of Curaçao (e.g. Boka Kalki), with the limestone terraces that are characteristic for many active blowholes.
