Harlesiel is a resort town on the East Frisian coast of Germany, at the mouth of the Harle River.
It lies in the Wittmund district, about 1 kilometre (0.62 mi) north of Carolinensiel [de].
[1] Harlesiel was founded in 1956, part of the last stages of the draining of the Harlebucht.
The inner and outer harbors of the town are divided by the pumping station which keeps the land dry; this building incorporates a lock to allow passage to the sea.
Many tourist attractions and facilities were added over the years including campgrounds, a beach, a salt water swimming pool, and a miniature golf course.
