Mosquito Springs Run is a 3rd magnitude spring with a series of vents in the main pool and run. These vents are labeled 1, 2, 3, 4, and 5. The spring head is at the bottom of a steep ravine. The ravine around the pool and run slopes upward 8 feet into a hardwood forest. The spring pool is about 20 feet long by 10 feet wide with two vents that issue water from limestone. Vent 1 is in the south part of the pool and vent 2 is in the north part. Green algae and white sulfur-reducing bacteria are present in the pool and there is a hydrogen sulfide odor.

The run, 4 feet wide, 0.8 feet deep, and 0.5 miles long, flows northeast into the St. Johns River. About 140 feet down the run, a tree can be used as a bridge to walk to the other side of the run to sand boil 3, situated in a small run on the south side of the main spring run. Sand boil 4 is in the main spring run about 20 feet toward the northeast of sand boil 3. The ravine becomes less steep downstream and the run flows into a broad wetlands area. Sand boil 5 is in a seepage area to the south-southeast of vent 3.


The area around the spring is undeveloped but there is a camping area in the upland area to the east of vent 5.
