• We rise early with the song birds and the leaf monkeys scrambling through the trees of our lodge compound in search of their breakfasts.
  
  
• After a hearty breakfast ourselves, we set off on a 3-hour rafting expedition down the beautiful Bohorok River. The grade 1-2 rapids along this route are perfect for rafts made of large inner tubes lashed together. This makes for a very wet, wild and wonderful river run – a complete immersion experience! What better way to learn about the hydrology of a river than to go with the flow, riding the chutes and haystacks, getting spun into back eddies and watching the force of erosion against cut banks?

• Returning by vehicle to our lodge, we enjoy a good lunch before setting off on a hike to a series of nearby caves. Here we will learn lessons in cave geology as well as investigate the interesting habits of cave creatures – cave crickets, cave hunter spiders, insectivorous snakes, cave racer snakes and edible nest swiftlets.

• Our last adventure of the day will be to cook our own dinner, forest dweller-style over an open fire. Students will face a real “Survivor” show challenge in building a fire, cutting sections of bamboo for cooking containers and tea cups, and steaming rice wrapped in banana leaves. Only animals and plants native to the Sumatran forest and river estuaries will make up this meal: chicken, ginger, black pepper, rice, durian, mangostene, rambutan, banana, etc.
