Turtle Spring pool measures 30 ft north to south and 66 ft east to west. The depth over the spring vent is 21.4 ft. The vent is an elongated fracture beneath a limestone ledge. The spring pool bottom is sand and limestone. The spring water is clear and greenish. Algae are abundant on both rock and sand substrates. Several downed logs are inundated within the spring pool. The spring run is shallow, 90 ft long and 20 ft wide. It flows into the dark waters of the Suwannee River. Limestone is exposed in the shallow spring run and near the vent. Turtle Spring is situated along the Suwannee River in a cove surrounded by 15-18 ft high sandy banks. The surrounding lands are all forested with mixed hardwoods.
Turtle Spring is located 8 miles (13 km) southeast of Branford on the west side of the Suwannee River. From the bridge over the Suwannee River in Branford head west on US 27/20 approximately 1.3 miles (2.1 km) to the intersection with SR 349. Head south (left) on SR 349 and drive approximately 7.3 miles (11.7 km) to the second CR 342 intersection with CR 349 (second CR 342 sign – CR 342 loops around and joins CR 349 at two points). Turn east (left) onto CR 342 and drive approximately 5 miles (8 km) to the Simms Landing boat ramp. CR 342 makes several right angle turns prior to the boat landing. The spring is 0.5 miles (0.8 km) downstream from the CR 342 boat ramp.
