The Naturalist Scouts is a great way for boys 11-17 to find adventure. This group is for teenage boys who are enthusiastic about the great outdoors. The group takes backpacking, canoeing, and biking trips several times a year, all over the country. Due to the scouts affiliation with Hostelling International, the only cost will be buying camping gear, paying for your share of food on a trip, and for any additional trip cost or extras.
