Ecologic Divers provided a combination Snorkel / SCUBA tour for my group of 13 out of San Pedro on an upscale Catamaran. All equpment was first class as was the ship crew and dive master. The group consisted of a 9 year old that swims like a fish to a Grandma that could not swim at all and had never been snorkeling. The snorkel guide was great and everyone enjoyed a spectacular day,.....even grandma on her first ever snorkel tour. Lots of fish, sharks, rays, sea turtles, and colorful coral reef.
