Longtail Lighthouse - The remaining tower from Longtail Point Lighthouse located about 1-1/2 miles North of the mouth of The Fox River. The lighthouse was built in 1847 and the limestone tower is all that remains. Once you reach the island by boat, the tower is accessible by traveling through thick vegetation, including wild raspberry bramble. Oh, and snakes! Not my favorite creatures in the world...fear, panic, running and some not so funny moments, may or may not occur on the island.
