Key Largo is one of the best, if not the best, in the USA. Amy Slates is good and so is Capt. Jack Slates ( Amys’ ex hubby) he runs a nice boat. I like "Its a Dive" It is Located on the Mariotte property ( I think it’s the Marriotte) it is on the south bound side of rt 1 and I think it is about mile marker 105 or near there. It is also a very good operation!!!! I always recomend it to any one looking to dive Key Largo. Have a nice time.
