I agree that going with a tour guide is the best plan in Ocho Rios. We went with Carolyn Barrett and had an awesome time. She is so knowledgeable about the island and pointed out many interesting things we would have never found if not for her. We visited YS Falls and it was gorgeous, not crowded at all. She even took us shopping on the way back to the ship, as some of us wanted to purchase the famous Blue Mountain coffee.
