DeLeon Spring is situated in a circular, conical depression measuring 189 ft (57.6 m) north to south and 168 ft (51.2 m) east to west. The maximum pool depth measures 28.0 ft (8.5 m) over the vent. The bottom is sand, except at the vent where some limestone is exposed. A single vent issues water from the center of the pool. The water is clear with a light greenish color. There was a visible boil over the vent during January 2002. There are patches of algae on the bottom and suspended algal filaments and particles in the water. No other aquatic vegetation is present in the spring pool. A concrete wall with numerous access ladders and a concrete sidewalk encircle the spring pool. The spring outflow pours through a concrete weir on the west side of the spring pool, then down a 3 ft (0.9 m) drop into the wide, natural spring run. From here, the spring run flows approximately 0.25 miles (0.4 km) westward into Lake Woodruff from the northeast. To the south and east of the spring, high ground gently slopes to approximately 6 to 8 ft (1.8 to 2.4 m) above the spring water level. To the north and west are swampy, forested lowlands of Lake Woodruff and the St. Johns River system. Surrounding land is developed and landscaped as part of the state park. Divers report a small underwater cave at DeLeon Spring (Rosenau et al., 1977).
The spring is within DeLeon State Park which has full facilities.
