    Entry Fee:
    Dive fees are $40 per person per day (as at Jan 2011). You must check in with your certification card at the main office/dive shop. They will hold your card until you collect it after your dive.

    Air fills, nitrox fills and full equipment rentals are available at this store also, and a complete video tape briefing of the dive will be given there to divers who have not dived Blue Grotto before.

    After you check in, follow the road down to the main parking area and pavilions; the spring is 100 feet down from the parking area, accessed via a floating dock.

    Amenities available at Blue Grotto:
    · Gear benches, racks and changing facilities
    · Picnic tables and pavilions
    · Restrooms and hot showers
    · Rinse showers

    Diving Blue Grotto:

    * All divers must show proof of certification before diving (or be under the supervision of a diving instructor). Dive within your certification level.

    * Dive within your depth limitations, i.e. open water divers are restricted to a depth limit of 60 feet.

    * Solo diving not permitted in Blue Grotto, if you do not have a buddy, you may not dive there.

    Divers should gear up at the pavilion, and walk to the floating platform with their fins in their hands. Take only the gear needed on the dive down to the spring itself. Lock all other gear and items in you car, as the owner is not responsible for anything lost or stolen. All buddy teams will do a pre-dive check before entering the water and buddy checks before descending. Entry is via a giant stride off the platform, or a walk in entry down the steps.

    Maintain visual contact with your buddy or instructor at all times, and maintain proper buoyancy and to avoid silting the area. Flow from the spring is extremely low, so anything silted up will remain in the water column for a long time. Perform a safety stop at 15ft/3M after all dives.

    Blue Grotto is a sinkhole with depths reaching 90 feet. When you enter the water, there is a series of platform in open water, and then a very large cavern, 20 feet wide and 80 feet high. There are artificial lights at 20-30 feet to illuminate the cavern. At a depth of 30 feet, up on the roof of the cavern, there is a fresh air bell so you can take off your mask and breath some fresh air! This very cool feature accommodates up to six divers at a time, to stop for a quick chat, or just take a breather! Remember that time in the air bell, still constitutes bottom time, as you are under pressure!

    Continuing down from the air bell, there is a large shaft that slopes down at a 90 degree angle. There is a thick rope that leads in a horseshoe shape through the very back of the cavern. This area is VERY silty when stirred up. Even if the cavern is clear, only tour the bottom if you have excellent buoyancy control, as visibility can be reduced to nothing in seconds after a careless fin kick.

    Special notes

    Be aware of divers on deco in the area. Do NOT touch any bottles that are by the steps, on the platforms, or at the entrance of the cavern. These are not treasure!, they are vitally important to exiting divers to complete their decompression.

    Do NOT enter the cavern unless certified to do so. The bottom of the cavern can get very silty, and is for advanced, experienced divers only!

    View out of Blue Grotto

    There is a highly visible yellow line at the 50 foot level that extends across the cavern, this cautions newer divers not to proceed past this.

    What you can expect to see:

    Wildlife you can expect to see when diving here are sunfish, catfish, small turtles and crayfish.


    Do not harass the fish or turtles!

    Water temperature in Blue Grotto is generally 72F year round. A 3mm wetsuit with hooded vest or thicker is recommended.

    Visibility ranges from 30-70+ feet. It is best early in the morning, before the crowds get there!

    Emergency Procedures:
    If anyone becomes low on air, signal your buddy with the appropriate hand signal and begin your ascent. In the rare and unusual case of an out of air situation, signal your buddy and commence sharing air. Maintain buoyancy and ascend slowly, remembering to breathe continuously.

    In the event that you are separated from your buddy follow standard procedure: search for one min (remember to look up and around, and for bubbles also). If you are unable to find your buddy ascend and meet up on the surface. Your buddy should also be following these procedures.

    If your buddy is not on the surface within three minutes, contact others in your group to find out if he or she has been seen/already exited the water. Air supply allowing, search the area where last seen. If the diver is not found, activate EMS.

    Emergency Contact Information:
    911 - This will activate EMS in the Chiefland area
