Diving into Nature’s Marvel

The Splendors of Hart Springs

As you explore Hart Springs, you’ll encounter the head of Hart Springs Run, where three merging spring runs converge. Notable features include:

  • The Middle Spring Pool: Measuring an impressive 51 ft north to south and 45 ft east to west, this pool boasts a depth of 19.9 ft over the vent. The water is crystal clear with a captivating greenish hue.
  • Prominent Boil: In the heart of the spring pool, a mesmerizing boil forms on the surface, created by the spring’s discharge.
  • Vent and Enclosure: The vent, a vertical limestone fissure with towering 15 ft walls, adds to the allure. A 4 ft high metal retaining wall encloses the nearly rectangular spring pool, extending southward to encompass the southernmost spring and its run.
  • Aquatic Abundance: Exotic aquatic vegetation thrives in the spring pool, while algae adorns the pool and the run. Additional aquatic plants grace the pool’s edges.
