The Masai Mara Great Migration timing for the most dramatic wildlife spectacle — the wildebeest Mara River crossings — peaks between late July and October, when approximately 1.5 million wildebeest (plus hundreds of thousands of zebra and Thomson’s gazelle) cross the Mara River from the Serengeti (Tanzania) northward into the Masai Mara (Kenya) and back again multiple times during the 4-month Mara occupancy period. Self-drive visitors planning their Kenya circuit specifically to witness a Masai Mara Great Migration crossing need to understand that individual crossings cannot be predicted — they depend on the wildebeest herd behaviour at the river bank — but knowing the Great Migration timing 2027/2028 calendar and the specific crossing locations maximises the probability of witnessing a crossing from a self-drive vehicle.
The Great Migration Calendar: 2027/2028 Masai Mara Timing
- June: First wildebeest herds arrive in the Masai Mara from the Serengeti. The Mara River crossings begin in late June in years with early rain patterns — but June crossings are early and unpredictable. Migration front is in the Masai Mara south and the Mara Triangle.
- July: The peak crossing period begins. The full Mara river crossing spectacle is most reliable from mid-July onward. The Kogatende crossing points (north bank of the Mara River) become active. Peak crossing frequency: 3 to 7 significant crossings per week at the busiest rivers.
- August and September: The most intense Masai Mara Great Migration timing period — maximum wildebeest numbers in the Mara, daily attempts at various river crossing points (Kichwa Tembo, Crossing Point 1, the Serengeti crossing). Best probability for witnessing a crossing.
- October: The herds begin moving south as the Serengeti short rains approach. Crossings continue but the herd movements become more southward-biased. Mid-October is the last reliable period for Mara River crossings.
- November to June: Wildebeest are in the Serengeti. The Masai Mara has excellent resident wildlife but no migration crossings.
Crossing Locations for Self-Drive Visitors
- Kogatende crossing points (north bank, MMNR): The most reliable Mara River crossing area — multiple established crossing points along a 5km stretch of the north bank. Accessed from the MMNR via Kichwa Tembo track (50km north of Seronera gate) or via Musiara gate. Drive time from Sekenani gate to Kogatende area: 1.5 to 2 hours inside the park.
- Mara Triangle (west of Mara River): The Mara Triangle crossings are from the west bank — often less crowded with visitor vehicles than the north bank. Access via Oloololo gate.
Self-Drive Protocol at Masai Mara Crossings
- Position the vehicle on the river bank path early (arrive at the crossing point by 7am) — good positions fill quickly as the crossing season peaks
- Switch the engine off once in position and wait — crossings can be triggered at any time from 30 minutes to 6 hours after the herd arrives at the bank
- Do not hoot, rev the engine, or move toward the crossing wildebeest — any vehicle movement that spooks the lead wildebeest aborts the crossing and can prevent any crossing for hours
- Wait times: experienced self-drive visitors budget a full morning (6am to noon) at a crossing point per day — some days no crossing occurs, others produce multiple crossings
