1. Volcano Boarding
Thousands of travelers head to the foothills of Nicaragua's Cerro Negro mountain every year to take part in the new sporting craze. Surfers, dressed in protective jump suits, knee-pads and helmets, can reach speeds of up to 80 km/h (50mph) on their specially-constructed plywood boards. Since its creation, in 2005, the volcano has attracted more than 10,000 participants.

5. Cliff Diving
This dangerous sport originated from the Hawaiian Island of Lana´i in 1770. Kahekili, the king, demanded that his men leap off high cliffs and the water feet first without a splash, to prove their courage and loyalty. Today, after centuries, the activity has expanded into a sport that is marked by immense courage, focus, thrill and risk.
Cliff diving is one of the riskier kinds of diving; hence, extreme caution is a must. To the benefit of the divers, certain standards have been set to minimize the risk factor. Some of these include determining the height of the jump (23 – 28 meters for men, 18 – 23 meters for women), an ideal entering speed of 75 – 100 km/h, and a free fall time of 3 seconds.
6. Freestyle Powerisers Stilts
7. Underwater Hockey
The game is played using nothing more than snorkeling equipment - and of course the stick, protective gear and gloves - which adds breathing as an important game factor, meaning players have to manage the oxygen in their body. The game is played at the bottom of the pool using a puck weighing over one kilogram. The sport is tough and tiring though it is not as bad for experienced divers capable of holding their breath for extensive periods of time. The sport is becoming increasingly popular around the world and some countries have formed national teams which take part in world championships.
Christian Schou holds the Guinness World Record title for the highest slackline after crossins a Norwegian fjord in Kjerag, Norway at 3,280 feet (1000 meters) — the equivalent of 3 Eiffel towers high.
