Hornsby Spring has a circular spring pool measuring 155 ft (47.2 m) north to south and 147 ft (44.8 m) east to west. Its depth at the vent is 34.5 ft (10.5 m). The water is clear and slightly greenish blue. The spring has an underwater limestone ledge on the north side under a floating walkway. Algae patches are growing on limestone substrate. The spring run is approximately 0.9 miles (1.5 km) long, 15 ft (4.6 m) wide and up to 5 ft (1.5 m) deep. It flows generally westward into the Santa Fe River. During the first FGS visit, the spring was not flowing. The FGS sampled the spring during a subsequent visit when a small spring boil was visible near the wooden walkway. This spring is situated on the edge of the lowland floodplain of the Santa Fe River. The floodplain is forested with cypress, gum, and maple. High ground on the east side of the spring rises steeply to 6 ft (1.8 m) above water level, then gently rises to approximately 15 ft (4.6 m) and is a rolling sand hills terrain. The uplands are open and grassy. An underwater cave system has been mapped at Hornsby Spring.
Hornsby Spring is the central feature of the privately-owned Camp Kulaqua. The spring is developed into a swimming and recreation area. There are numerous boardwalks over and around the spring. A slide leads into the spring pool on the north side. Full facilities are located nearby.
