The tropical rainforest—thought to be the oldest land-based ecosystem on earth—is certainly the most diverse. Campers grab their pith helmets and journals as they venture across the Smithsonian to discover the unique and mysterious Amazon. A visit to the National Zoo’s Amazonia exhibit brings campers close to the animals that thrive along the Amazon River. Throughout the week, they explore the layers of the forest and its flora and fauna. A visit to the Museum of the American Indian brings the campers closer to the culture of the region. Campers create an immersive rainforest for families to enjoy, inspired by the week's journey.
