The Lonely Planet Travel Guide has this to say about Dawn on the Amazon Tours & Cruises; "This small but cozy outfit offers the best deal for independent travelers. It sports two modernly equipped wooden craft for either day trips or longer river cruises up to two weeks, and you can travel with host Bill Grimes and his experienced crew along the Amazon, or along its quieter tributaries. Dawn on the Amazon has exclusive permission to go twice as far into Pacaya-Samiria National Reserve as any other tour company."

I agree with this author.
