Blue Grotto Dive Resort

Dive with one of our Divemasters or Instructors

Cavern

Let’s face it: No one knows Blue Grotto and Devil’s Den better than we do. Why not let us share them with you? We can guide individuals, buddy pairs and small groups. Divers with limited experience are no problem. We will make your visit unforgettable.

90% of those who dive Blue Grotto and Devil’s Den won’t see half the things we can show you

Here is just a small sample.

After diving Blue Grotto, we can go across the highway to Devil’s Den. It would be a shame to drive all the way to Williston and not experience both sites. Both are equally breathtaking but neither are anything like the other. See for yourself.

How much?

Our divemasters and instructors are independent contractors. As such, you will make a single payment to them that will cover:

  • Your guide’s time and travel
  • Dive site admission
  • Equipment rental (if any)

You can do this using cash, Venmo, Cash App or Zelle. How much you will pay will depend on:

  • Whether you will be diving just Blue Grotto or both the Grotto and Devil’s Den.
  • Whether you have all your own equipment or will need to rent one or more items.

Here is current per-person pricing:

If you are just diving Blue Grotto

If you just need tanks, weights$164
