Fountain of Youth Archaeological Park, Archaeological park and National Register of Historic Places site in St. Augustine, Florida.

This 15-acre waterfront park features the legendary spring associated with Ponce de León's quest for eternal youth, along with reconstructed Timucuan village buildings, Spanish colonial exhibits, a planetarium, and a 600-foot riverwalk offering scenic views of the historic bayfront area.

The park has been promoted as the likely 1513 Florida landing site of Juan Ponce de León, though no evidence substantiates the claim; research by amateur historian Douglas Peck points instead to the Melbourne Beach area. Excavations by Dr. Kathleen Deagan in the 1990s uncovered remains of the first Spanish settlement and its fortifications at St. Augustine. The grounds were listed on the National Register of Historic Places in 2016.

The park's name and its well come from a legend, not from evidence: no proof links the site to Ponce de León's 1513 voyage. Archaeologist Kathleen Deagan's 1990s excavations here uncovered remains of the first Spanish settlement and its fortifications in St. Augustine. Luella "Diamond Lil" McConnell, who enlarged the attraction from 1904, invented stories to amuse and shock visitors until her death in 1927.

The park operates daily from 9:00 AM to 6:00 PM with tickets sold until 5:00 PM, offers free parking, welcomes pets, and provides half-price admission to St. Johns County residents upon presentation of valid identification.

Visitors can drink from the natural spring waters that flow continuously and have been linked to the fountain of youth legend for centuries, while peacocks roam the grounds and Spanish cannon demonstrations recreate the sounds of colonial times.
