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.

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.
