My partner and I recently finished a 4 day tour of the Amazon and it was phenomenal, in large part thanks to May. His tour exceeded our expectations in every sense. He adapted the tour to customize the experience for us including accommodating a vegetarian diet and the excursions themselves to match our interests (we especially wanted to focus on local birds and bugs). He was extremely knowledgeable about the names of all of the flora and fauna (even down to specific bugs) as well as their behaviours and their cultural context.  Each day was packed with activities with everything from nocturnal walks, to river birdwatching, to hikes.  The experience back at the lodge was also incredible. The food was delicious and they made every effort to bring some comforts of home to the jungle in an eco friendly fashion. In addition to all this, he is obviously dedicated to providing opportunities and respecting the traditions of the local communities. If you're looking for an authentic and personalized Amazon guide , I cannot recommend May enough.
