Harvey's Cave is a technical shore-entry cave system in Northwest Florida Springs, reaching depths between 20 and 73 metres. The site presents a challenging overhead environment characterised by strong currents and variable visibility ranging from 1 to 18 metres. Water temperatures fluctuate between 13 and 25 degrees Celsius, with a warm halocline noted at 49 metres. Due to the significant depth, entanglement risks, and complex navigation, this site is strictly for advanced divers with formal cave certification. Divers must maintain precise buoyancy control and monitor gas supplies closely. Night diving is possible for qualified teams, though the hazard profile increases significantly in low-light conditions.

Cherokee Sink is a shore-entry cavern and cave site in Northwest Florida. The topography features depths ranging from 20 to 24 metres, with an average depth of 18 metres. Visibility is variable, typically between 2 and 6 metres. Due to the overhead environment, divers must manage risks including entanglement, nitrogen narcosis, and potential decompression obligations. This site is suited for intermediate divers with cavern certification, as the conditions require precise buoyancy and air management. Facilities at the site include parking and toilets. Divers should be prepared for low visibility and carry primary and backup lighting equipment for this 40-minute dive experience.

Sally Ward Spring is a technical cave and cavern site in Northwest Florida Springs, United States. The system features depths ranging from 3 to 20 metres. Divers access the site via a shore entry with on-site parking. The environment is defined by its overhead nature, requiring full cave certification and disciplined gas management. Visibility fluctuates between 6 and 21 metres depending on flow and penetration depth. Divers must maintain strict buoyancy control to prevent silting in the confined passages. Redundant lighting is necessary for navigating beyond the cavern zone, where passages become completely dark. The site is suitable only for expert divers due to the overhead environment and variable visibility.

Little Blue Spring is a freshwater shore-entry snorkel site in the United States. The site features a spring vent reaching depths of 13 metres, though most snorkellers remain in the shallower sections. A mild current makes the site suitable for beginners. Underwater, the habitat supports various freshwater fish and invertebrates. Visitors should exercise caution regarding entanglement risks from submerged tree roots and aquatic vegetation near the spring vent. The site offers full facilities including parking, toilets, showers, changing rooms, and a cafe, allowing for convenient access. Water temperatures fluctuate between 13C and 32C throughout the year, and visibility can vary significantly between visits.
