Mahale Mountains National Park is Tanzania’s most remote and magical chimpanzee trekking destination.

Why Mahale Is Special
Mahale Mountains National Park is unlike any other safari destination in Africa. The park covers 1,613 square kilometres of montane forest, bamboo groves, and lakeshore beaches along Lake Tanganyika. The Mahale Mountains rise to 2,462 metres, creating a dramatic backdrop for chimpanzee trekking. The park is only accessible by boat or light aircraft — there are no roads. This isolation has preserved one of Africa’s largest chimpanzee populations and created an atmosphere of true wilderness. The combination of forest trekking, beach relaxation, and crystal-clear lake swimming is unique in Tanzania.
Chimpanzee Trekking Experience
Chimpanzee trekking in Mahale is a wild and immersive experience. Treks begin early morning, following trails through dense forest as guides track the chimps by their calls and fresh nests. Encounters are never guaranteed — the chimpanzees are wild and move freely — but the Mimikire group is habituated and sightings are reliable. When you find them, you spend one hour observing their behaviour: feeding, grooming, playing, and interacting. The experience is intimate and powerful — watching our closest relatives in their natural forest home.
Getting to Mahale
Mahale is remote. The most common access is a charter flight from Arusha or Dar es Salaam to the park’s airstrip (Sumbu or Mgambo), followed by a boat transfer to your lodge. Alternatively, fly to Kigoma (from Dar es Salaam) and take a 3-hour boat ride across Lake Tanganyika. The journey is part of the adventure — Lake Tanganyika’s crystal-clear waters and mountain backdrop are spectacular. Most visitors spend 3 to 4 nights in Mahale, combining it with a Katavi safari for the ultimate western Tanzania circuit.
Frequently Asked Questions
How difficult is chimpanzee trekking in Mahale?
Mahale chimpanzee trekking is moderately challenging. Treks involve hiking through dense forest on steep, sometimes muddy trails for 2 to 4 hours. Fitness is important — you need to be comfortable walking uphill on uneven terrain. The humidity can be intense. However, the pace is adjusted to the group, and guides are experienced at finding the chimpanzees efficiently. Unlike gorilla trekking which is more physically demanding, Mahale trekking is accessible to most reasonably fit adults. Minimum age is typically 12 years.
What is the best time to visit Mahale?
June to October is the best time to visit Mahale. Dry season conditions make forest trekking easier — trails are less muddy and chimpanzees are easier to locate as they stay closer to the lakeshore. The lake is calm and clear for swimming and snorkelling. November to May is the wet season — trekking is more challenging but still possible, and the forest is lush and green. Some lodges close during the heaviest rains (March to May). For the best combination of weather and chimpanzee viewing, visit between July and October.
How do I get to Mahale Mountains?
Mahale is remote and access is limited. The easiest option is a charter flight from Arusha or Dar es Salaam to Sumbu or Mgambo airstrip, followed by a boat transfer to your lodge. This takes approximately 3 to 4 hours total from Arusha. Alternatively, take a scheduled flight to Kigoma (from Dar es Salaam), then a 3-hour boat ride across Lake Tanganyika. The boat journey is spectacular — the lake is crystal clear and surrounded by mountains. Most visitors combine Mahale with Katavi National Park for a complete western Tanzania circuit.
Should I choose Mahale or Gombe for chimpanzee trekking?
Mahale offers a more exclusive and comfortable experience than Gombe. Mahale has more chimpanzees (1,000+ vs 100), better lodge accommodation, and a more developed tourism infrastructure. Gombe is smaller, more famous (Jane Goodall’s research site), and has a more rugged, budget-friendly feel. Mahale’s lakeshore setting with beach relaxation is a major advantage. Gombe is closer to Kigoma and cheaper to access. For most visitors, Mahale is the better choice — the combination of excellent chimpanzee viewing, comfortable lodges, and lake activities creates a more rounded experience.
How much does a Mahale safari cost?
Mahale is one of Tanzania’s most expensive destinations due to its remoteness and limited accommodation. A 3 to 4 night Mahale safari typically costs £2,500 to £5,000 per person including charter flights, lodge accommodation, meals, and chimpanzee trekking permits. The two main lodges — Greystoke Mahale and Kungwe Beach Lodge — are luxury properties with prices reflecting their exclusivity. When combined with Katavi National Park, a complete western Tanzania circuit costs £4,000 to £7,000 per person. The high cost is justified by the extraordinary experience — Mahale is genuinely one of Africa’s most special wildlife destinations.
