Praise for The Impenetrable Forest . . . 

"Thor Hanson's memoir is a fascinating and enjoyable read.  Particularly timely, it gives us great insight into conservation and ecotourism in a world that is often harsh and cruel.  More so, though, Impenetrable Forest transforms the mountain gorillas of Uganda and the people who care for them into deep, complex, loving characters. "

Garth Stein, NYT Bestselling author of The Art of Racing in the Rain

"...a downright wonderful book.  A fine writer and a superb naturalist, he brings the true observer's eye and the artist's sensibility to one of the most compelling subjects in all natural unforgettable book—funny, tragic and brilliant."

—Robert Michael Pyle, Sky Time in Gray's River and Where Bigfoot Walks

"Like a warm cup of sweet Mexican atole on a cold morning, this book fills your belly and makes you smile."

—Lawrence F. Lihosit, Across the Yucatan

"Thor Hanson’s ‘The Impenetrable Forest’ takes us on several remarkable journeys.... Hanson’s lighthearted, yet poignant stories of life in Uganda make you feel like you are right next to him throughout his adventures and misadventures.  The book uniquely intertwines the natural history of mountain gorillas with the culture of the people that live as their neighbors.  I highly recommend this book to anyone who wants a personal account, yet well-rounded view, of the conservation issues surrounding a charismatic species such as the mountain gorilla."

—Martha M. Robbins, PhD, Department of Primatology Max Planck Institute 

 "Great reading for everyone with a sense of adventure and interested in protecting our natural world."

—Craig R. Sholley, African Wildlife Foundation

"Thor Hanson spent two years protecting the Mountain Gorillas of the Bwindi Impenetrable Forest, saving their habitat as he habituated them to tourists, and bringing a source of income to the villagers living at the edge of this remote forest in southern Uganda. If you love to read about people who’ve made a difference, Thor’s life—full of successes and disappointments—makes a fascinating, inspiring memoir.” 

—John Coyne, Living on the Edge: Fiction by Peace Corps Writers

"Thor Hanson’s Impenetrable Forest is a fascinating account of African reality that explores vital issues for the survival of mountain gorillas.  It is an engaging personal story of change and challenge, an articulate natural and cultural history, and a clear call to conscience to preserve habitat and species."

—Phil Condon, Montana Surround

the impenetrable forest: gorilla years in uganda

Curtis Brown Unlimited, 2014; 1500 Books, 2008



Lying in the remote hills of southwest Uganda, Bwindi

Impenetrable Forest harbors elephants, chimpanzees, monkeys, and half the world’s population ofendangered mountain gorillas.  For two years, Thor Hanson called that forest home, working with local guides and trackers to develop an ecotourism program for the newly-formed Bwindi Impenetrable National Park.  Thoroughly researched and beautifully told, Hanson’s story
blends natural history with cultural insight to place the forest and the gorillas in the context of modern Africa. 
The Impenetrable Forest offers a rare glimpse into the world of mountain gorillas, and the human cultures that
surround them.  A must-read for anyone interested in gorilla tracking, endangered species, or travel to Uganda.
