December is the month Tanzania safari operators look forward to all year. The long rains are over, the parks are drying into their classic golden look, and the wildebeest calving season is beginning in the southern Serengeti. Add a Kilimanjaro climb to the itinerary and you have one of the most extraordinary travel experiences on earth — all in a single trip. December is also the month that requires the most advance planning: peak-season pricing, limited operator availability, and the Christmas holiday rush mean that booking late is not an option.
Why December Is One of the Best Months for a Tanzania Safari
December sits at the beginning of Tanzania's short dry season — and the beginning of the wildebeest calving season in the southern Serengeti. After the long rains (March–May) and the short rains (November), December brings clearer skies, easier road conditions, and wildlife that is beginning to concentrate around the permanent water sources that define the dry season. The landscape is transitioning from green to gold — one of the most beautiful transitional states the Serengeti achieves.
The calving season — which typically runs from late December through February, peaking in January — is one of the most dramatic wildlife spectacles on earth. Approximately 8,000 to 10,000 wildebeest calves are born every single day during the peak, and the predator response is immediate and intense. Lions, cheetahs, hyenas, and leopards concentrate around the calving herds. For wildlife drama, December rivals any month of the year — and it comes with the bonus of a clear, dry Kilimanjaro summit day.
December Kilimanjaro and safari is one of the most sought-after travel combinations in the world. The mountain is accessible, the summit views are generally clear, and the safari is at its wildlife peak. The cost is high and the crowds are real — but the experience is genuinely extraordinary. Book early, travel in the first half of the month or after January 3, and you will have the best December can offer.
Climbing Kilimanjaro in December: The Dry Season Begins
By December, the long rainy season is definitively over. The mountain trails are drying out — not fully dry yet (that is more June), but transitioning. The lower slopes are still green from the November rains, the waterfalls are still running, and the landscape is at its most varied and beautiful. The summit zone above 4,000m is cold and clear, and December summit days are among the most reliable of the year for visibility.
December is accessible on all the major routes, and the trail conditions are generally good. The main issue is crowding: December is peak season on the mountain, and the Machame Route in particular can feel busy in the first few days of the ascent. The Lemosho Route is the best choice for those seeking a quieter experience — it approaches from the west, has lower traffic than Machame, and offers the most scenically varied ascent.
Summit queues at Uhuru Peak are a known issue in late December — particularly around December 31, when dozens of climbers reach the summit at the same time for the New Year sunrise. If your summit day falls on December 30–31, discuss adjusting your itinerary with your operator. An extra day on the mountain — or a slightly different start date — can mean the difference between a solo sunrise summit and a crowded plateau.
The December Safari: Southern Serengeti at Its Most Dramatic
December is the month the southern Serengeti and Ndutu come into their own. The wildebeest herds that spent the long rains dispersed across the eastern and southern plains are beginning to concentrate, and the calving season is getting underway. By late December, significant herds are typically visible on the short-grass plains south of the main Serengeti — an extraordinary landscape of golden grass stretching to the horizon, punctuated by thousands of wildebeest and zebra.
Ngorongoro Crater is excellent in December: the crater floor is dry, the wildlife is concentrated around the remaining water sources, and the rhino — resident year-round — are readily seen. Tarangire National Park is often bypassed in December in favour of the Serengeti, but it is worth including if your itinerary allows: the elephant herds are present, the park is beautiful in the dry season, and it is significantly less crowded than the Serengeti.
Managing December Costs: The Early-December and Post-New Year Windows
December is the most expensive month for Tanzania tourism — and the most expensive time is the Christmas peak: roughly December 20 through January 3. The industry-wide premium for these dates is real and unavoidable. A 14-day Lemosho + Northern Circuit safari departing December 22 costs approximately $6,760–7,200 per person. The same itinerary departing December 10: approximately $5,408–5,800. The post-New Year period (January 5–12) returns to high-season pricing but below the Christmas peak.
If your schedule is genuinely flexible, the single best December money move is to travel in early December (December 1–15) or in the post-New Year window (January 5–15). Both windows offer the excellent wildlife viewing and dry-season conditions of peak season, with meaningfully fewer crowds and lower prices than the Christmas peak itself.
The Best Route and Safari Circuit for December
For December, the 8-day Lemosho Route is our recommendation for most climbers. It provides the best acclimatisation profile, the most scenic variety, and lower traffic than the Machame Route. The longer 8-day itinerary is particularly valuable in December because it distributes the altitude gain more gradually — and the extra day on the mountain is a buffer if your summit day falls in the crowded December 30–31 window.
The safari circuit for December should prioritise the southern Serengeti and Ndutu — this is where the calving herds are, and this is where the wildlife drama of December is concentrated. Ngorongoro Crater is a non-negotiable addition on any December safari: it is excellent year-round, and the dry-season concentration of wildlife makes December a particularly good month for crater sightings.
Packing for December: Dry Season Kit
December is dry season — so the wet-season kit of April or May is not required. The packing list is closer to the standard Kilimanjaro kit: layered clothing from rainforest warmth to summit freezing, with sun protection being the December-specific essential. The equatorial sun at altitude is intense in December — the skies are clear and the UV index is high. A high-SPF sunscreen, a wide-brimmed hat, and quality sunglasses are non-negotiable on safari and important on the mountain.
For safari, the dry-season palette applies: light neutral clothing in tans and light browns. Avoid white and black — these are more visible against the dry grass and can startle wildlife. Binoculars and a camera with a zoom lens are essential for the calving season: predator action can happen at distance, and the detail on newborn wildebeest calves is worth zooming in on.
Who December Is Right For — and Who Should Choose a Different Month
December is right for: families whose school holidays fall in December or early January; travellers who want the clearest possible summit day conditions; anyone whose primary goal is the wildebeest calving season; and travellers who have booked far in advance and can manage the peak-season costs. December is emphatically not the right month for budget travellers — the premium is steep and unavoidable — or for travellers who specifically want a quiet, uncrowded mountain experience.
If December costs feel too high, the best alternatives are: November (20–30% cheaper, short rains just beginning, wildlife still excellent), January 5–20 (post-peak pricing, excellent wildlife, fewer crowds), or April (green season at its most lush, 40–50% cheaper than December, some rain).
