This was a terrific group tour. Wonderful itinerary, with hikes that could be modified for various levels. Lots of very interesting sights. Included hotels were very good. Our guide, Pili, made sure everyone was well taken care of, from the sprinters to the turtles and that all were having a good time. Her depth of knowledge in so many areas was truly impressive (including geography, culture, history, ecology, flora and fauna). Her passion was infectious! The group included single travelers as well as couples, and people came from several different countries.
