Boscastle Blowhole
Nearly horizontal blowhole that can be observed shortly before or after low tide, at rough sea. Sometimes the fountains go some 30 – 40 m far.

Slanted plume of water that shoots through a narrow hole that goes through the rocky island. Here is also Post Office or Devil’s Letterbox – hole that sucks in the air. The suction is sufficient to “swallow” a letter.
