Green Springs, also known in the past as Green Sulphur Spring and Green Spring, was long the jewel of the park and a popular attraction for tourists and travel writers, who found its waters exotic, strange, and often ethereal, with more than one visitor admiring their delicate green color. Once said to be bottomless, the spring actually has lateral vents and a widening shaft descending 76 feet to a silt-covered limestone floor. Algae and sulphur affect its color, while dry spells can darken the water and even stop its discharge. When the spring runs, its waters join a small creek that drains other nearby springs and eventually flows into Lake Monroe. The retaining wall dates from the 1940s, when owners of a swimming concession replaced the natural outlet to create a shallow area for children. Over time the place drew a wide cast of people, including Florida natives, Seminole Wars soldiers, and Cornelius Taylor, who promoted his spring in the 1840s with bottled water and promises of good health. Decades later the area still attracted visitors from far and near, while legends persisted, including tales that the spring appeared overnight after dynamiters drained another spring to the north, or that a wagon fell into it and emerged from a vent in the ocean. Mystery remained central to the experience, and in the 1860s one traveler to Enterprise felt she had left America for some foreign realm amid weird, wild, luxuriant nature.
