Where to start from exploring caverns to hanging out with curious and entertaining sea lions, to being greeted by a large manta, and swimming through HUGE encompassing schools of jacks while they form a tornado- like a wall around you, the experience so far with the Nautilus on the Sea of Cortez has been magical. The crew is also very attentive and the food is spectacular. Fresh baked goods daily, drinks always available, five-star dining for a liveaboard. I would definitely do another trip with them.
