Come to Blue Grotto and you will experience first hand what Jacques Cousteau himself discovered about diving the Florida Springs. Blue Grotto in Williston is home to the largest accessible underwater cavern in north-central Florida. Sport divers can reach depths of 60 feet while still keeping the entrance clearly in sight. It's one of just four sites in the region where you only need an Open Water Diver certification to experience a safe, enjoyable cavern dive. Visibility often exceeds 100 feet. Additional features include:

✅ A large dock makes entering and exiting easy.

✅ Large bathhouses with warm showers inside and out.

✅ Cabins, cottages, tent camping and RV slots on site.

✅ Instructors can take advantage of our classroom, pool, covered pavilions and training platforms.

✅ On-site air and Nitrox fills. For more in-depth information on the Grotto, visit our website at https://divebluegrotto.com.

THIS IS THE BEST WAY…
…to carry a tank. The worst way is to walk around with the tank clutched to your chest — especially while descending stairs.

FEARLESS, FRIENDLY FISH

■ At most dive sites, the fish keep their distance. Getting within arm’s reach is almost impossible.

■ But at Blue Grotto, it’s a different story. Our friendly bluegills will swim right up to you — especially if you offer them their favorite treats.

■ And once you feed them, don’t be surprised if they start following you around like a pack of lovesick puppy dogs. It’s one of those uniquely Blue Grotto experiences that never fails to make divers smile.

NO BUDDY? NO PROBLEM

■ Our highly experienced divemasters and instructors can show you the things 90% of visiting divers miss.

■ After diving Blue Grotto, we can also take you to nearby Devil’s Den. It would be a shame to come this far and not dive these two equally exciting but totally different sites.

■ We can also guide couples, buddies and small groups.

BE CAREFUL WHAT YOU WISH FOR...

For the past several months, we've been hoping for enough rain to end the drought and restore Blue Grotto's water level. Yesterday afternoon, we got exactly what we asked for. The skies opened up, and it poured for more than two hours.

When we checked the water afterward, the Grotto had turned into one giant mud puddle. Not just poor visibility—no visibility.

The last time this happened, Blue Grotto was forced to close for several weeks. Fortunately, this time was different.

The heavy rain also brought a dramatic increase in groundwater flow, flushing out most of the sediment overnight.

Conditions aren't quite back to normal yet, but they're improving rapidly. The good news is that Blue Grotto will be open this weekend after all.
