The park has two ravines up to 120 feet deep with steep banks at 45 degree angles. Unlike common gullies, trenches or sinkholes caused by temporary flooding, the steephead ravine is a permanent feature with a spring-fed creek that never dries up, called Whitewater Branch. The underground water bubbling up cuts into the bank and carries the sand and soil downstream to the St. Johns River.
Known for: The Ravine Loop is closed to vehicle traffic one hour before sunset, but remains open for pedestrians, bicycles, and wheelchairs. The garden's peak flowering period is azalea season, late January to April. Numerous picnic sites, equipped with tables and grills, are available to visitors.
