We picked SharkSky tours for our day trip to Leon Dormido for two reasons: our Lonely Planet guidebook recommended them, and when we went around town to compare tours they were the same price as everyone else, but were the only operator that offered two chances to snorkel at kicker rock instead of one at kicker and one off of Isla Lobo. We were so, so happy with the tour we received! While checking out Isla Lobo, someone spotted a piece of trash in the water. The large boat came to halt and somehow maneuvered itself so someone could grab it before we went on our way. The guide was fun, friendly, knowledgable, and had a sense of humor along with excellent English, and the captain was also a really nice guy. The lunch they served was amazing, a really tasty rice dish, salad, fruit, and juice. We would certainly go with SharkSky for other tours.
