Are you looking for something to do? You might like to try one of these four experiences. Crocodile watching Do you fancy getting up close to some of the most terrifying animals on earth? Crocosaurus Cove, in Darwin (Australia) has the "Cage of Death". It's an enclosure that's lowered into a pool. This gives you a 360 degree view of a crocodile as it's being fed. The cable broke once and the cage sank to the bottom, but they've fixed it since then. Edge walk How about walking along the edge of a building several hundred meters up in the air? If that sounds like fun, head off to the CN Tower in Toronto (Ontario, Canada). Built in 1976, the tower is 553.33 meters tall. The Edge walk consists of a 20-30 minute stroll along a 1.5 meter wide platform that runs around the tower's restaurant roof. During the walk, you're encouraged to lean forwards as you look over Toronto's skyline  . Plastic ball rolling Do you fancy rolling down a hill in a plastic ball? Plastic ball rolling is popular all over the world, but the place to give it a go is in Rotorua (New Zealand). Brother David and Andrew Akers came up with the idea in 1994. A typical orb   is about 3 meters in diameter, with an inner orb size of about 2 meters. There's no brake or steering mechanism, but the inner layer of the plastic ball helps absorb the shock. Volcano bungee jumping If you're looking for the adventure of a lifetime, how about going bungee jumping off a helicopter into the crater of a live volcano? As part of the jumping, a helicopter ride takes you to the Villarreal volcano, one of the most active in Chile. Once you're at the drop zone, you leap off the helicopter and fall into the volcano. Finally, you enjoy the ride back to the airport flying at 130kph. Attracted by the above? If so, please contact us. Only half price from March 22 to April 25th.
