Guatemala (S05E03)

The Walsh family arrives in Guatemala and gets their hands on a new vehicle, which proves to be a real challenge for Bradley to handle. They venture into the jungle, where they rappel down a cliff face into a waterfall and encounter an eccentric shaman who swears by the restorative properties of chocolate. After that, they set off for a bike ride, but Barney conveniently neglects to tell his dad that they're pedaling along a tightrope suspended 25 meters above the ground.
