The spring water is naturally rich in sulfur, which contributes to the distinct scent often noted by visitors.
The park is situated on the site of the former Clarendon Hotel, a grand destination during the Florida winter tourism boom of the 1870s.
The spring produces approximately 1,200 gallons of water per minute.
The pool bottom is lined with concrete, contrasting with the natural sandy bottoms found in many other Florida springs.
A historic fountain remains in the park as a remnant of its 19th-century landscaping.
The park's spring run flows directly into the St. Johns River just a few yards from the main pool.
The area was originally used by the Timucua people before the development of the Victorian-era resort town.
Spring Park is home to a natural, sulfur-fed spring pool that maintains a constant temperature of 72 degrees Fahrenheit year-round. Located on the banks of the St. Johns River, the park features historic remnants of 19th-century luxury resort architecture, including remnants of the Clarendon Hotel era. The swimming area is fed by artesian water flowing through a concrete basin designed for public recreation. The park grounds span approximately 2.5 acres and provide direct access to the St. Johns River waterfront. Picnic pavilions, playground equipment, and public restroom facilities are available for visitor use. The site serves as a community gathering space for the Green Cove Springs area.

Do not expect a pristine wilderness experience; this is an urban park with a paved pool setting rather than a remote natural spring.
The spring pool may be closed periodically for maintenance or due to water quality testing; check the municipal website for current operational status.
Proper swimming attire is required in the pool; glass containers are strictly prohibited within the park boundaries.
