Darwin was a very caring guide.  If anybody had a concern, he was there with a solution. My camera broke the second day of the trip and he went with me to a local camera store so I could replace it. Other people needed things from a pharmacy and he was right there for them. he was very knowledgeable and really loved his country. We met his family at one location and she made us each a lei and baked a birthday cake for one of the women.
