Walk the jungle tree tops in Costa Rica. Arenal Hanging Bridges, Costa Rica - A three kilometer hike through the Costa Rican rain forest. There are six suspension bridges, with the largest one at just under 100 meters long and 45 meters off the ground.
One cannot go to Panama City without taking the opportunity to watch the ships traversing the canal through the Panama Canal Locks. I found great fun in watching the ships enter each gate and raise to enter the successive lock.
