The grotto is used for training, open water diving, and is available for private parties and special events. The Grotto walls are hour glass shaped loaded with solution tubes and other objects to look at. The bottom is dome shaped, and the edges average around 100 - 110 feet in Depth. with the deepest spot, about 155ft in a small opening against the north wall. There are four platforms, Three of them just under the end edge of the dock, and one in the middle of the sink. The three platforms are layered like steps, the first one is at 20ft.,the second at 45 ft. and the third at 60ft. Tied to the white barrel there is a line that runs down to a 100 foot platform which is used for Advance Open Water classes.  The Platform sits next to two boats and lines run to an old VW van, and other interesting objects sitting on the bottom. There are several thermo clines, the mid-water temperature can get pretty cold between 40 and 80 feet , however the bottom temperature usually stays in the low 70's.  The water is tannic all year, and visibility can really fluctuate with the algae bloom. Cost is usually around 10- $20 for divers depending on visibility.

Located one mile North from the intersection of SR 52 and US Hwy 19. Tower Drive is directly across the street from the Castriota Chevy Dealership. Hudson Grotto is on the left side of Tower Drive, just across the street from Scuba West dive shop.

Hudson Grotto

This was the last dive for my AOW.  I explored several wrecks along the bottom.  The sulfur layer was a little thicker than my visit two days ago.  Bottom is very silty and can easily be stirred causing bad vis to be worse, so use caution. We managed not to stir things up. This location offers experiences for all divers.  New divers should remain shallow, as surface light can be lost as soon as 50ft on some days.  You should still bring a light to look into holes and solution tubes.
