On the central campus of BTU Cottbus-Senftenberg, children aged 6 to 12 can get in the mood for their well-deserved summer vacation with active sports at the BTU's Children's Sports Days. For 3 days, they are supervised by BTU students from 9:30 a.m. to 4 p.m. and can try out and let off steam in various sports in the sports hall, on the sports field, and on the climbing wall. A day of swimming in the neighboring "Lagune" is also often on the agenda.
