There are many ways to experience a tropical rain forest: taking a hike, sliding down a zip-line, or via canoe, elephant, helicopter or jeep. Those are all great options. But in our view - if its possible, and especially if you're short on time - the very best way is to take flight on an aerial tram that will take you gliding through and ultimately above the foliage. All of your senses will be engaged, and while you won't emerge on an adrenaline high (at least, as long as the equipment is operating properly), there's the very real possibility that you might return from the forest having had a spiritual epiphany. We recently visited the Caribbean island of St. Lucia for the first time, and we decided to give the island's Aerial Tram a go. The adventure takes only about an hour from start to finish, and it's a truly ethereal experience.
