O’Hanlon has become known for his journeys into some of the most remote jungles of the world (Borneo, the Amazon basin and Congo). He also has written a harrowing account of a trip to the North Atlantic on a trawler.
In the Netherlands, Redmond O’Hanlon was a guest and co-presenter on the program the Beagle: In Darwin’s wake, made for VPRO Television. For the same broadcasting organization another series was made in which he introduces the viewer to his heroes of the nineteenth century. The program was called O’Hanlons helden (O’Hanlon’s heroes) and was awarded with the prestigious Dutch television award ‘De Zilveren Nipkowschijf’.
