As the closest national park to Arusha, this often-overlooked gem offers an incredible diversity of wildlife and landscapes within just a few hours’ drive. Your journey begins in a lush mountain forest, home to colourful turacos, blue monkeys, and the acrobatic black-and-white colobus monkey, a rare sight elsewhere on the northern safari circuit. In the heart of this forest, the dramatic Ngurdoto Crater encloses a marshy floor dotted with grazing buffalo and warthog herds.
Further north, the beautiful Momela Lakes glow in shifting hues of blue and green, frequently tinged pink by thousands of flamingos alongside elegant waterbucks, giraffes, zebras, and tiny dik-diks. While large predators are rare, the park is dominated by the majestic Mount Meru, Africa’s fifth-highest peak at 4,566 metres. A rewarding trek up its slopes leads through wooded savannah and giant lobelias where, at dawn, the clouds often clear to reveal stunning, sunrise-kissed views of its famous neighbour, Mount Kilimanjaro, just 50km away.
A small park with four landscapes in one
At just 137 square kilometres, Arusha National Park is one of the smallest parks on the Northern Circuit, but it packs in more scenery per kilometre than almost anywhere else in Tanzania. In a single morning you can move from open savanna grazed by giraffe and buffalo, through montane rainforest thick with black-and-white colobus, up onto the ash cone of an extinct volcano, and finish beside an alkaline lake turned pink by thousands of lesser flamingos. It sits roughly 25 kilometres — about 45 minutes — northeast of Arusha, which makes it the easiest national park in the country to combine with a single free day rather than a full safari.
Giraffe country, and the Momella Lakes
The park holds one of the highest densities of giraffe anywhere on the continent — several hundred animals in an area a fraction of the size of the parks further west — alongside zebra, warthog and Cape buffalo on the open ground around Ngurdoto Crater, sometimes called the “little Ngorongoro” for its steep forested walls and swamp-filled floor, though vehicles stay on the rim and never descend into it. To the north, the seven shallow Momella Lakes vary in colour from lake to lake depending on their algae and mineral content, and their shallows draw flamingo, pelican and a long list of waterbirds against a backdrop of Mount Meru.
Momella Lakes and flamingos
One of the few parks you can walk in
Most Tanzanian national parks restrict visitors to vehicles, but Arusha National Park is a rare exception: guided walking safaris with an armed ranger are permitted across much of the lower park, and canoeing on the Momella Lakes is offered as well — a genuinely different way to close in on buffalo and giraffe at the waterline. The park is also the starting point for treks up Mount Meru, Tanzania’s second-highest peak at 4,566 metres, a four-day climb that serves many people as acclimatisation before an attempt on Kilimanjaro and, on a clear day from the upper slopes, offers one of the best views of Kilimanjaro itself.
Why it is usually a half-day, not a full safari
Because it sits so close to Arusha and covers so little ground, most visitors treat it as a morning or afternoon addition rather than a standalone safari — either on arrival before heading out to Tarangire and the rest of the circuit, or as a gentle final outing before flying home. Predator numbers are low compared with the Serengeti or Ngorongoro, and that is rather the point: this is a park for walking, canoeing and giraffe, not for big cats.

Highlights, up close
Where it is
- Best time to visit June to October and January to February
- Climate Wetter and cooler than the plains thanks to Meru's slopes — a light waterproof is worth carrying even in the dry season.

Landscape & vegetation
Open acacia savanna and swamp around Ngurdoto Crater, montane rainforest on Meru's lower slopes, and shallow alkaline lakeshore at Momella.
What you might see
A seasonal reference guide, not a live sighting feed or a guarantee — wildlife moves. Tap or hover a ring for a quick note.
- Giraffe Near-certain on most visits to this area.
- Cape buffalo Near-certain on most visits to this area.
- Black-and-white colobus Spotted on the large majority of game drives here.
- Warthog Spotted on the large majority of game drives here.
- Lesser flamingo Depends on the time of year — ask about timing when you enquire.
- Leopard A genuine bonus sighting if it happens — never guaranteed.
Notable birds
Lesser flamingo ◆ Pink-backed pelican ◆ Silvery-cheeked hornbill ◆ Crowned eagle
Right now: this list is at its fullest. Resident species are here year-round, and this is also the window (roughly October to March) when migratory birds visiting from Europe and Asia add to the count.

A closer look
Before you travel What to carry, health precautions & emergency numbers Packing list, vaccinations, and who to call if you need help.
What to carry
- Neutral-coloured clothing (khaki, olive, brown) — avoid bright white, black and blue, which attract tsetse flies
- A warm layer or fleece — early-morning game drives and the Ngorongoro rim are cold even on the equator
- Wide-brimmed hat and polarised sunglasses
- High-SPF sunscreen and lip balm
- Insect repellent (DEET-based, for dusk and dawn)
- Binoculars — one pair per person makes a real difference
- A power bank and universal adapter (Tanzania uses UK-style Type G plugs)
- A soft-sided duffel bag rather than a hard suitcase, for light-aircraft and 4x4 luggage limits
- A basic personal first-aid kit and any personal medication in hand luggage
- Cash in US dollars (2013 or newer notes) for tips and small purchases
Health precautions
Malaria
Northern Tanzania is a malaria risk area. Speak to your doctor or a travel clinic about antimalarial medication well before you travel, and use insect repellent and cover up at dusk and dawn regardless.
Yellow fever certificate
Tanzania requires proof of yellow fever vaccination only if you are arriving from (or have transited more than 12 hours through) a country with risk of yellow fever transmission. If that applies to your routing, carry your International Certificate of Vaccination.
Altitude
The Ngorongoro Crater rim sits above 2,200 m and Kilimanjaro/Meru climbs go much higher — mild headaches or breathlessness are common at altitude. Drink plenty of water, ascend gradually where you can, and tell your guide if you feel unwell.
Sun and hydration
The equatorial sun is stronger than it feels in the open-sided safari vehicles. Drink more water than you think you need, and reapply sunscreen through the day.
Routine vaccinations and travel insurance
Make sure routine vaccinations are up to date, and take out travel insurance that explicitly covers emergency medical evacuation — the parks are remote, and evacuation by light aircraft is the standard response to a serious medical issue.
General guidance only, not personal medical advice — please confirm requirements and recommendations with your own doctor or a travel clinic before you go.
