The tropical rainforest—thought to be the oldest land-based ecosystem on earth—certainly the most diverse. Campers don their pith helmets and take their journals as they venture across the Smithsonian to discover the unique and mysterious Amazon. A visit to the National Zoo’s Amazonia gets campers up close to the animals that thrive along the Amazon River. Throughout the week, campers explore the layers of the forest and its flora and fauna. A visit to the American Indian Museum 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.
