 Collider Activity Center Concept

If there is a quality that unites successful people, this is their energy. The successful people are active people: those that love action, risk, and new opportunities; those that create value. Walltopia will build for them the Collider Activity Center – a place that gathers all active people and offers unlimited combinations of sports, rest and networking.

The different types of climbing walls, fitness center, swimming pool, dance and sports halls – those are just a few things that will attract the active people in Collider Activity Center. Furthermore, there will be a boulder park, a spa center, a bar and a restaurant. One of the biggest advantages of Collider Activity Center is that it will unite many popular activities in just one place, next to a major underground station and a great view to Vitosha Mountain.

In addition to avoiding the wandering between different locations by providing a big choice of activities, Collider Activity Center will save time that everyone can invest in themselves in stead of spending it in traveling. Often while we are in a hurry and have not enough time, we have to choose just one activity per evening or we have to compromise with the wishes of our friends and relatives. But Collider Activity Center will provide a solution for this problem.

 In short, this will be a point of attraction for all active people, no matter if they are working in business or arts, no matter what age they are or whether they are experts or beginners. Collider Activity Center is for people that love movement, for those that after the busy working day will refresh while practicing sports or having fun with friends. We would like this place both to bring tranquility, but also to show  the strong spirit of the people inside.
