We then hike for several hours along a rain forest ridge learning about the flora and fauna of the world's oldest terrestrial ecosystem. Wildlife sightings may include: hornbills, orangutans, macaque monkeys, langurs, White-handed gibbons, and Siamang – the world's largest gibbon

Our rain forest ridge hike concludes at Eco Lodge where we stop for refreshments before setting off to explore a series of connected caves rich in bats, swiftlets, cave aquatic life and invertebrates.

Lunch will be served jungle style on the banks of the Landak River. Student teams will challenge one another in a “Survivor Sumatra” exercise where they must start their own fire, cook rice and eggs in bamboo, bake fish in mud ovens, dig wild ginger for tea and serve it in bamboo cups. Skilled jungle guides will assist each team in this unique and fun-filled learning experience
