Yes you have to drive out in a van packed with people and you have to walk through some nasty mud, but this trip is UNBELIEVABLE ! We had a single guide and he was courteous, funny, and responsible. Going out in that bay in a moonless night is an experience you just can't get anywhere else. Jumping this water... more

We were at the appointed place 10 minutes early and waited 15 minutes past the pick up time and then made our way to the next pick up location with no luck. Late had a message... more

First of all, I would suggest looking around at the choices you have. We went with Eco Action Adventures, and there uncoordinated call backs and unorganized approach should have been an indicator.
