Are you brave enough? What about trying something like these ones?
It is really one of the most breathe taking sports. A distinctive feature of BASE jumping is that the jumps are usually made from low altitudes and the athletes involved in it don’t have much time to find out the convenient position for the body position after the parachute opening. The payment for this delay is extremely high. Independent attempts usually result in serious injury or death.
These dives are made in caves. At first glance, there’s nothing difficult, but in fact, such a diving can be extremely dangerous. Sometimes swimmers have to swim in the darkness, and in the dangerous case it is hard to come to the surface.
This kind of sport means diving with special equipment. In order to go down under the water, you need to be trained to get certain diving skills.
This hobby is just jumping from a helicopter and skiing on pristine mountain slopes. Using helicopter allows you to find remote places, which are impossible to be climbed in other ways. The main danger is a high probability of an avalanche, so every skier should have the special and professional equipment, which in case of any emergency will help to find a person as quickly as possible.
