When to go on safari
Tap a month to see what's happening in the Serengeti and beyond.
January
High seasonThe short rains have passed and the southern Serengeti plains turn into a nursery — calving season is underway and the plains are thick with newborn wildebeest.
- ✓Wildebeest calving begins around Ndutu and the southern short-grass plains
- ✓Predators move in close, so game drives stay eventful
- ✓Warm, mostly dry days make for easy, comfortable game drives
WOW!!! TRIP OF A LIFETIME
This was my first safari experience and what a great one it was. Olsero Expedition really made the process so enjoyable. We were a group of 30+ people. Faraja and his crew treated us so well. In my group, our driver was Richard and he was extremely knowledgeable about the animal and plant life all around the Serengeti. We saw the Big 5 and much more, plus we got to see 2 White Rhino. What an amazing experience. Highly recommended 10/10.— Adventurer710328 · Friends · Jun 2026Read on TripAdvisor
