Ovis Cave

(1,033 ft/315 m). Upstream section of the Catacombs tube system, separated into individual caves by a series of collapse trenches. Smooth floors and ceiling heights exceeding 7 ft (2 m) are found throughout this cave.

Hercules Leg Cave (1,948 ft/594 m) and Juniper Cave (2,362 ft/720 m). These two caves were connected by the removal of debris in a collapse pit, and together make one long excursion with an entrance and exit. The Hercules Leg portion has generally high ceilings and smooth floors. The connection to the Juniper branch involves crossing a breakdown with a passage height of 2.5 ft (0.8 m), and several low sections thereafter.

(6,903 ft/2,104 m). This very long cave is easily entered but gradually increases in difficulty. It is possible to walk upright for approximately 800 ft (244 m) to the stairway, after which the ceiling rarely exceeds 3 ft (0.9 m). A few places exist where the ceiling height is less than 12 in (30 cm). A cave map is highly recommended for any group planning to explore the entire length, as multiple levels and numerous side passages can be confusing. This cave is not recommended for inexperienced cavers.

(466 ft/142 m). Two collapses allow sunlight to enter the cave and abundant vegetation grows. Stooping is required in the main passage, and the back section has floors that are steep and sometimes wet, or very rough. There is beautiful hydrophobic bacteria coating the ceiling at the back of this cave, and icicles adorn cracks in the ceiling in winter.

(1,541 ft/470 m). Named for the pale blue-gray portions of the ceiling inside the "Blue Grotto". The ceilings are high throughout this cave but the floors are rough.

(1,405 ft/428 m). Named for the rich brown color of lava coating the ceiling and walls. Stooping is required in a couple places, and there is one passage with a ceiling height of 3 ft (0.9 m) that requires duck-walking.
