I went to Cayo Blanco with the Catamaran experience. I was extremely disappointed with the beach. I went on this excursion primarily for the white sand beach and turquoise water but could not believe the amount of seaweed on the beach. It had an acrid odour and it was necessary to "wade" through the seaweed to get to the ocean. This issue is easily remedied with a rake and a bit of man-power. It really detracted from the overall experience. That being said, the food was delicious and plentiful.
