Devil’s Ear Spring is situated at the mouth of a 375 ft (114.3 m) long spring run that enters into the Santa Fe River from the south side. It is an elongated limestone fissure that discharges directly into the adjacent Santa Fe River. The spring pool measures approximately 105 ft (32 m) east to west and 60 ft (18.3 m) north to south. The vent is an oval shaped opening in limestone with steep sides leading down to a depth of 34 ft (10.4 m). There is a large boil over the spring vent. Dark water from the river contrasts distinctly with clear, bluish water issuing from the spring along the side of the river. Native aquatic grasses are common around the vent opening, and some algae are on grass blades and limestone walls. The banks on the south side of the river rise steeply to approximately 3 ft (0.9 m) above water level, then levels off. On top of the bank, a mesic hardwood forest with interspersed clearings is present. An underwater cave system has been mapped at Devil’s Ear Spring.
Devil’s Ear Spring is located among a complex of springs on the south bank of the Santa Fe River. The spring is approximately 6.5 miles (10.5 km) northwest of High Springs and can be accessed either by river or through the privately owned Ginnie Springs Resort. From the junction of US 441/41 and US 27 in High Springs, drive southwest on US 41/27 for 0.8 miles (1.3 km). Turn west (right) on SR 340 (Poe Springs Road), drive 6.6 miles (10.6 km) west on SR 340. Following the signs to Ginnie Springs, turn north (right) on a graded road and go 1.2 miles (1.9 km) to the Ginnie Springs Resort entrance. Follow the road around to the back of the office and towards the river. Turn right just before the bathhouse and follow the sand road to the parking area. Devils Ear Spring is part of a complex of three vents and is the vent nearest the Santa Fe River.
