The Sapphire Blue Hole is easy to get to and just off the same road that goes to Preacher’s Cave in North Eleuthera. The turn into the road is also easy to miss so make sure you look at the Google map to see where to turn to the right as there are a lot of little side roads to farms along the way.
Here’s a shot that gives you more detail as to where the road is.
You can easily jump in from the edge and there is a knotted rope so that you can easily get back up or that’s what I’ve been told about the easily getting back up part. I didn’t attempt it the day I was there because I was by myself. Does that work as an excuse? I definitely would have if I were 20 years younger or there was a ladder!
