Devil’s Bridge in Antigua

Devil's Bridge in Antigua

Natural bridge at the sea with a stormy basin between the bridge and mainland. The bridge is some 20 m long and up to 4 m wide. There are several smaller blowholes at this natural arch.

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.
