Yes, malaria prophylaxis is highly recommended for travelers visiting the Masai Mara National Reserve in 2026. While the reserve's high elevation (around 5,000–6,500 feet) makes the risk lower than in Kenya's coastal regions, the reserve is still considered a malarious area. Mosquitoes that carry the Plasmodium falciparum parasite are present, particularly after the rainy seasons. Common tablets prescribed include Atovaquone/Proguanil (Malarone), Doxycycline, or Mefloquine. You should consult a travel clinic at least 4–6 weeks before your trip to determine which medication is right for you, as some must be started several days before arrival. In addition to tablets, you must practice "bite avoidance" by using DEET-based repellents, wearing long sleeves at dusk and dawn, and sleeping under mosquito nets. Even if you are taking tablets, these physical barriers are your first line of defense against malaria and other insect-borne illnesses like Dengue fever.
