An amazing experience - of a lifetime for people my age! Darwin Alvarez was outstanding! In many trips abroad with many leaders, I have never come across anyone with such a complete knowledge of his subject(s)! History, geology, meteorology, birds, fish, plants, insects - awesome! His self-taught English was also flawless - so were his diving/snorkelling abilities!
An excellent holiday that exceeded my expectations. The Naturetrek group was extremely good and we all hit it off! Darwin Alvarez was a brilliant guide, superlatives are not enough. He was easy going, very knowledgeable and patient, a credit to the Galapagos national park service.
