Florida spring

Siphon Creek Rise

Siphon Creek Rise is known for its clear, 72-degree water and a flow of about 3,398 liters per second (215 million gallons per day). Set along the Santa Fe River’s southern bank, its cave system basin—up to 30 feet deep—offers a challenging spot for cave diving, surrounded by dense forest. Accessible by public land or boat from Hollingsworth Bluff ramp off SR 47 (0.5 miles downstream), it’s in a remote area, so navigate carefully. Summer weekends draw divers—arrive early for calm. For quiet, visit weekdays in spring (April-May) or fall (September-October), mornings ideal. Water can cloud with Santa Fe River backflow after rain. Check —stable water levels to ensure clarity, clearest from late fall to early spring during dry periods.
