Athletic adventure-seekers are often looking for options the gym can’t offer. While outdoor activities like running and biking have long been a staple of indoor athletics thanks to treadmills and spinners, the next generation of indoor recreation is putting extreme sports, typically reserved for rough and geographically-limited terrain, to the indoors. With the use of artificial snow and simulators that can mimic anything from surf waves to wind for sky diving, indoor arenas make these sports accessible to just about anyone who is game, regardless of season or climate.

So whether you’re an amateur wanting to test the waters, or even a highly proficient athlete, you won’t need to wait for the right weather or a jet setter’s income to fly you around the world to participate in your favorite sports. Here is psychoPEDIA’s list to the world’s best indoor recreation:

Indoor Skiing
Ski Dubai
Dubai is known being the playground of the rich, where almost anything is available that money can buy– except maybe, snow. However, with the introduction of Ski Dubai, tourists and locals can now experience the world’s largest indoor snow park right in the middle of a desert. The standard package price to ski or board includes your entire snow outfit of pants and jacket, ski poles or board, ski or snowboard boots, helmets for children, and even disposable socks. Ski Dubai features five runs of different levels and also the world’s first indoor black run. If your skills aren’t up to par to take on the slopes yourself, you can take group or private lessons. And for simple frolicking in the snow, Ski Dubai also offers a Snow Park with toboggan run and climbing wall.

Indoor Surfing
The LC , Swansea, Wales
For a typically dreary climate, the people of Wales have found a way to bring a little sunshine to their lives. The LC is Swansea’s modern water park, reopened in March 2008 with new refurbishments and high-tech additions maintaining the standards of the past, being home to the first wave pool in Wales. New additions include The Boardrider, an indoor surf machine that’s the first of it’s kind in the world, and riders can either choose to boogie board or surf the never-ending wave. Not only does the surf center provide a safe environment for first timers, but the sensation is as close to the real thing without actually being at the beach. The LC also houses water slides, water rides, whirpool, interactive pool, and a lagoon.

Indoor Scuba Diving
Nemo 33, Brussels
If you thought you needed an ocean to go scuba diving, think again. Nemo 33, located in Brussels, is the world’s deepest diving pool with a depth of 33 meters. The pool, about three floors high, has five meters exposed, which can be viewed from the outside. Divers are expected to show their diver’s certification to experience this man-made pool filled with rooms and passages to explore, which are also used on film shoots. The water is unchlorinated pure spring water with a temperature maintained at a comfortable 33 degrees Celcius (92 F), so you can enjoy the caves and view the stalactites. All equipment is provided, and professional instructors are available to guide and train for those who are uncertified.
