Being omnipresent, all tourism enterprises in the regions are impacted by seasonality. At certain times of the year, Maasai Mara National Reserve has more tourists than they are able to accommodate, while at other times, there are few tourists to the National Reserve. The research was based on qualitative method where primary data was gathered from the managers whilst secondary data was gathered from legitimate sources i.e. Tourism Board of Kenya, Ministry of Tourism among others. Semi-structured interviews were used in the research; the target group was 5 managers in Maasai Mara. The findings depicted that Maasai Mara National Reserve is very much affected by seasonality since it is located in a remote area, poor road maintenance during the rainy season, seasonal migration of wildlife between the reserve and Serengeti National Park in Tanzania and finally the hotels and camps majorly rely on international tourists who tend to visit in large numbers during the wildlife migration in July and August.
