Blue Grotto Dive Resort - Williston FL


Loading...
All you need to dive this 100 ft. cavern is an open water certification!

This is the Blue Grotto sinkhole, not the cave.

Blue Grotto is part of the Florida aquifer system it’s fed by the springs in the area and maintains a constant 72-ish degrees year round. This paradise-like dive destination offers training platforms for students, a great cavern system and a cool fresh air dive bell filled with compressed air from the surface. Don’t forget to say hi to Virgil the resident soft shell turtle.

The dive begins at the mouth of the cavern, which is 80ft wide and 20ft high. Look from topside into the sharp blue of the pool and you will understand why Blue Grotto is well known for its exceptional visibility year round. 30ft below the surface is the only air bell available to spring divers in the region, filled with fresh compressed air that allows you a unique opportunity to stop and talk with your buddy under the water. Descending from there, at 50ft a permanent guideline brings you to the crescent shaped cavern where you will experience an array of fossils along the walls of the chamber and an abundance of aquatic life (bluegill and catfish) waiting for a free handout. But words will not do justice to the experience of diving in this breathtaking underwater hideaway.

This Dive Resort offers a fully equipped dive shop and shelters for your diving gear. Shelters can be reserved via email or phone. There is also a bathhouse with hot showers.

Bring your friends to enjoy a BBQ on your surface intervals at one of our many picnic pavilions. You can even play basketball while you wait for your gear to dry.

Make sure to ask about our rooms, so you can enjoy the Blue Grotto for as long as you like.

Excellent cavern dive with platforms located at 20 and 30 feet with an airbell at approximately 25ft.
Maximum depth is 100ft and approximated diameter is 75ft in width with an overhead beginning at 25ft.
Numerous shelters with picnic tables and large restroom facilities with changing rooms and showers.
And if you’re really lucky a (female) turtle named Virgil will come by and visit with you for a while.

I went scuba diving here on 9/19/2017. Average viz: 91-100ft/28-30m. Water temp: 71-75°F/22-24°C.
Tues. 9/19/17 - Helped new OW diver Ashley Peterson get acquainted with running lines underwater at Blue Grotto. First dive was a warm-up and get acquainted dive, playing with Virgil and doing photos. Second dive was working with a reel and 2 spools. Ashley did great with her buoyancy control, setting and retrieving the lines, as well as gas management. Ashley told me that including our dives she now has about 30 dives total.

I just happened to go to Blue Grotto as a backup because a shark’s tooth dive in Venice got blown out (two days).

I called the Gotto on a Thursday morning before Memorial Day weekend and, as luck would have it, they had one pet-friendly cabin remaining for Thursday night only.

I left Venice around 11:30 AM and arrived at Blue Grotto around 3:30 PM. I was hoping to find a dive buddy but, the place was almost deserted and everyone who was staying there had already finished diving for the day.

So, I paid a little extra to have the resident dive instructor (Kevin) take me on a guided tour of the Grotto. Also, one of the other staff members went along a videoed the dive. I have no idea what they’re going to do with the video.

Anyway, we did about a 40 minute dive. We went all the way to the bottom of the cavern (actually around 91 feet - Bottom is 100 feet). On the way back, we stopped in the air bell (30 feet). Kevin asked me if I wanted to go back and see anything again or if I wanted to do anything else. Honestly, I was so tired from the drive up and the dive to that point, I had to pass.

For those who have never been to Blue Grotto before, I would highly recommend paying the extra money for the guided tour to get familiar with the spring. For me, having never been there before, and just getting back into diving after a long absence, it was well worth it.

Glad to hear you were able to dive BG. Very beautiful place and terrific staff. I’ve been diving there twice so far and thoroughly enjoyed my time there. Plus, I got to meet Virgil.
SantaFeSandy - 5/28/2017 9:52 PM
Very nice story. I’ll pass it back to Kevin, Kurt, & Susan.
SantaFeSandy - 5/28/2017 9:53 PM
By the way, next time, if you need a buddy, I’m only 5 miles away.
fletch944t - 5/30/2017 2:42 PM
Thanks Sandra. I’ll definitely going back to BG. And, due to time constraints, did not get to do the swim-throughs over at Devil’s Den. As diving is not an option for my better-half, I’ll be in constant need of a dive buddy.

Merry Christmas y’all! It’s a bright and beautiful Sunday at the Blue Grotto.

Today’s dive started out as a commitment to help a newly certified open water diver, who then canceled an hour and a half after the agreed upon meet time.

Two weeks ago Paul said he’d be in town for Christmas and that we could dive cave on my day off, but being that I’d already given my word to help this young diver, rather than break it, Paul opted to join us, dive open water, and see the Blue Grotto for his first time ever.

What appeared to be lemons turned into lemonade due to nobody else being in the crystal, clear water.

Paul got to meet & feed Virgil and her buddies, and I got a few good shots in the process.

We shared a lovely day together, and seeing the pics of Paul, I couldn’t be more proud of my first, true protege. Paul is refining his skills remarkably well, and I have no doubt that the world will be hearing about his accomplishments and ventures, in the near future!

What a wonderful gift it is to witness such accomplishment.

One of the best spring/cavern dives in all of North Florida due to the fact that it is primarily for divers only.

So many cool people partaking of the beauty at Blue Grotto today. Good to see Jared and Taylor Hires, Bill Dutton, Phil Rankin, and the list goes on... Of course, being with my buddy George Claude, from NC, was super special.

Managed to get a few good shots of Virgil, and the gang too. Lots more yet to be edited and uploaded.

I totally agree. Awesome diving spot!

Two buddies and I drove 11 hours to dive at this paradise-like freshwater spring the day before Hermine hit the Florida coast (9/1/16). There was no one else around, so we had the place all to ourselves.

BG is an exceptional dive experience. The crystal clear water is a constant 72 degrees, with plenty of fauna and flora to see.

One of its most surprising features was the abundance of nooks and crannies that allow for safe "tight squeeze" training opportunities.

Blue Grotto is a very memorable dive destination, and I will definitely visit again the next time I’m in the area.

Good site for training. Staff is excellent. We stayed in the cabins and enjoyed the quietness and solitude. My daughter was able to compete all her training here.
