Blue Hole Spring pool is elongated and measures 159 ft east to west and 258 ft northwest to southeast. The depth of the spring pool is variable and measures up to 26 ft. The spring has a sand bottom. Thick patches of filamentous green algae cover about half of the spring bottom. The water color is greenish and murky. No boil was visible on the water surface in June 2002. Water lettuce is abundant in the southeast portion of the pool. The west side of the pool has a limestone boulder wall with stairs leading down to a sandy swimming area. The south side of the spring has a wooden footbridge over the outflow channel. The east side has a limestone boulder wall and a wooden swimming dock. On the north side of the main pool, there is another much smaller pool that is separated from the main pool by a narrow land bridge.
There is a wooden walkway that leads over the land bridge. The spring run discharges south approximately 1.6 miles into the Chipola River through a heavily forested lowland. All immediate surroundings are landscaped with grassy lawns, scattered tall pines, picnic tables, restroom facilities, and parking area. The ground rises gently away from the spring on the west side to approximately 10 ft above water level. Blue Hole Spring may be a river rise of an underground channel of the near-by Chipola River.
Blue Hole Spring is located within the Florida Caverns State Park, 3 miles north of Marianna.
