Our family of four (daughters age 12 and 14) went with a local guide to Cano Island and it was one of the most memorable parts of our month long trip in Costa Rica. We were able to see humpback whales including a baby whale jumping not far from our boat, and dolphins on our way to the island. The snorkeling was great... rays, white tipped shark, schools of tropical fish of vibrant colors. When we return to Drake Bay, we will definitely return to Cano Island and next time try diving. San Jocecito beach is also a great place for snorkeling. It would be a distinct advantage to have some washroom facilities at the ranger station on the island, as it is a deterrent for some to go on a tour knowing that there are no washrooms available. We had to delay our tour for this reason when one of our daughters was feeling unwell one day, and thankfully we had 6 days in Drake Bay so could reschedule.
