UNWTO published a report on wildlife watching tourism in Africa. The paper is based on a survey, which involved 48 African tourism and conservation authorities and 145 international and African-based tour operators. Wildlife watching represents 80% of the total annual sales of trips to Africa and sales are increasing. A typical wildlife watching tour is 10 day long, with average group size of 6 participants. The average price per person per day of a standard wildlife watching tour is US$ 243 and US$ 753 for a luxury wildlife watching tour, with an average of US$ 55 out-of-pocket spending per day.
