Mahale Mountains National Park (Chimpanzee & Trekking)

Nestled on the remote eastern shores of Lake Tanganyika, Mahale Mountains National Park is a true wilderness jewel, home to the world’s largest protected population of eastern chimpanzees—an estimated 700 to 1,000 individuals thriving in their natural forest habitat.

As an ecologist’s dream and a traveler’s paradise, Mahale boasts over 337 bird species, including rarities like Pel’s fishing owl, and lies within the biodiversity-rich Albertine Rift. The Park overlooks the second-deepest freshwater lake on Earth, whose shimmering waters harbor over 400 fish species, including more than 250 colorful, endemic cichlids found nowhere else. Remote, untouched, and soul-stirringly beautiful, Mahale offers an unmatched blend of primate encounters, birdwatching, and aquatic wonders, making it one of Africa’s most extraordinary hidden treasures.

Climate.

Mahale Mountains National Park experiences a tropical climate influenced by Lake Tanganyika, creating a warm and humid environment throughout most of the year. The Park enjoys a distinct wet season from November to April, with heavy rains that nourish the dense forests and create lush green landscapes. The dry season, from May to October, is generally cooler and more comfortable for hiking and chimpanzee tracking, with clearer trails and better wildlife visibility. The lake moderates extreme temperatures, keeping daytime highs between 25°C and 30°C (77°F to 86°F) year-round, while nights can be cooler, especially in the higher elevations.

Best Time to Visit.

The best time to visit Mahale Mountains National Park is during the dry season, from June to October, when the forest trails are more accessible and chimpanzees are easier to track as they move closer to the lake in search of food. This period also offers spectacular views of the Mahale mountain range and excellent opportunities for boating, swimming, and photography along the shores of Lake Tanganyika. While the park remains open year-round, visiting during the dry months ensures a more comfortable and rewarding wilderness experience with fewer logistical challenges.

How to Get There.

Mahale Mountains National Park is a remote and pristine destination, accessible only by air or water. The most efficient way to reach the park is by taking a scheduled or chartered flight from Arusha, Dar es Salaam, or Kilimanjaro International Airport to Kigoma Airport. From Kigoma, visitors can either charter a private boat (approximately 4 to 6 hours) or take a light aircraft to Katumbi airstrip near the park. Alternatively, a multi-day boat journey along Lake Tanganyika can offer a scenic and adventurous route.

Due to its remoteness, Mahale is best visited as part of a well-organized tour package, often combined with neighboring attractions such as Gombe Stream National Park.
