Three hours from the capital city of Accra, Ghana's Kakum National Park features the kind of dense forests that characterize much of the country’s south. This walkway is more than 1,000 feet long with an average height of 130 feet above the forest floor. Though most people consider it secure, the walkway is hardly state-of-the-art: It consists of wire rope, aluminum ladders and wooden boards. Additional netting is meant to provide an extra layer of safety. The canopy walkway and park are part of a conservation project that allows local people to focus on making income from tourism instead of from logging, farming or poaching.
