A small locally owned operator running the Kaieteur day tour at USD 375, including the flight from Ogle, the park pass, a certified guide, the three standard viewpoints — Boy Scout, Rainbow and Johnson's View — snacks and taxes. Groups are typically twelve, and the day runs five to six hours. They also do a Georgetown heritage and culture tour.
Note this one is not on the Guyana Tourism Authority's licensed-operator register as of March 2026, though the company presents itself as locally licensed. Worth asking about directly.
WhatsApp is advertised explicitly on their Kaieteur page as the way to reach them.
