I first visited Sierra Leone in late March 2017 for a fabulous 10 days. The mammal watching far exceeded expectations both in terms of the diversity of species we encountered but also the rarity of many of the species we found, with mega mammals like Water Chevrotain, Yellow-backed Duiker and Pygmy Hippo.
Beyond the mammal watching, a trip here is a real chance to help with conservation efforts. The community run forest on Tiwai Island, for examples, relies on a very few ecotourists each year for its sustainability. So a trip to Sierra Leone is a chance both to see some amazing mammals but also to feel virtuous in the process. I visited two sites: Tiwai Island, and Gola Rainforest National Park.
I spent four nights here in March, 2017 and our group saw the following. There was exceptional primate watching with 10 species seen: Demidoff’s Galago, West African Potto, Western Pied Colobus, Western Red Colobus, Olive Colobus, Sooty Mangabey, Campbell’s Monkey, Diana Monkey, Lesser Spot-nosed Monkey and Green Monkey. We also heard Thomas’s Galago. Other species included a Lord Derby’s Anomalure, Red River Hog, Gambian Sun Squirrel, Red-legged Sun Squirrel, Miller’s Striped Mouse, Allen’s Wood Mouse, Straw-colored Fruit Bat, Buettikofer’s Epauletted Bat, Noack’s Roundleaf Bat, Beatrix’s Bat and an unidentified horseshoe bat.
Gola Rainforest National Park
I spent 6 nights here in April 2017 and our group saw Hammer-headed Fruit Bats, Demidoff’s Galago, Thomas’ Galago, West African Potto, African Palm Civet, Giant Squirrel, Slender-tailed Squirrel, Fire-footed Rope Squirrel, Pygmy Hippopotamus, Red River Hog (heard), Water Chevrotain, Royal Antelope, Maxwell’s Duiker, Yellow-backed Duiker and Western Tree Hyrax. We also heard Chimpanzees.
Elsewhere we saw a Green Squirrels and Striped Ground Squirrels.
The World’s Best Mammalwatching
Sierra Leone’s Tiwai Island and Gola National Parks might not be the most luxurious destinations (OK, they are definitely not…) but they protect some of the last remnants of West African forest and some superb mammals including Pygmy Hippos, Royal Antelope, Diana and Red Colobus Monkeys and Hammer Bats. Every visit there helps protect this forest. See more of the World’s Best Mammalwatching.
