Graviton is our boulder gym, situated in Sittard and easily reachable by train (5-minute walk from Sittard station) or by carpooling. As MaasSAC has a contract allowing members to climb without additional charge on Tuesday evenings, this is where most of us will be found! From 5 pm until 11 pm you can exercise, practice, and last but not least socialize. Here you will find everything a boulder-heart desires, from easy beginners routes to difficult problems that will take weeks of practice and endurance. If you are new to MaasSAC, Maastricht, or even the Netherlands, you will be sure to meet some great people and feel right at home in the climbing community.  For more information on Graviton, visit their official website:

IVY is the home of MaasSAC sports-climbing! Situated in the small town of Sittard, it is the biggest climbing hall in the Benelux. This is the place where you can show your top-rope and lead-climbing skills on various routes ranging from the 2nd all the way to the 8th grade for the real professionals. The best part? As a MaasSAC member, you climb for free on Thursdays! Join our MaasSAC Carpool to organize a ride; costs are always shared between members (2-3€ both ways). If you have your IV-license, you can rent a rope there and lead climb, otherwise bring your own! The MaasSAC ropes cannot be rented for indoor lead-climbing. For more information on Ivy, visit their official website:

Since the completion of the new UM sports center, Maastricht University has a small but useful climbing wall! The wall gives you the chance to climb whenever you want and in between studying sessions. On Mondays, the wall is reserved for MaasSAC members exclusively. If it gets too crowded on Monday, you can kindly ask non-MaasSAC members to leave. However, if not all the routes are taken, try to work something out! For more information on Ivy, visit their official website:
