I went to Blue Hole on Monday. There was two of us...a taxi cost us $40 and a $10 entrance fee. We did not jump or walk the ladder going deep down into the spring but we did get in the pool. The guide told us they are trying to build a hotel towards the back of the property...So far, it looks good! I'm not sure about any tours but the taxi we used also took us to the "Bob Marley" Hole. Its a cave with spring water, the locals said Bob was a frequent visitor.
