My wife and I thoroughly enjoyed our week on the Letty. I picked Ecoventura because it was an local company, it focuses on the environment, the ships were small and they emphasized snorkeling. The wildlife on the Galapagos islands is amazing but what made the trip special were the naturalist guides, the crew, the food and our fellow passengers. The guides, Yvonne Mortola and Martha Chica were knowledgeable, friendly and worked very well together. We could not have asked for better guides. The food was outstanding — much better than on many of the large cruise ships we have sailed on. The crew could not have been more helpful — from loading luggage to dingy driving, to cleaning our room several times a day. If you are going to cruise in the Galapagos, then I highly recommend Ecoventura and try and find out when Yvonne or Martha (or if you are really lucky both of them) are going to be guides and book that week.
