If you feel uncomfortable in tight crowds, please avoid the front of the stages or other crowded areas. If you however get surrounded by a crowd, try to remain calm. Don’t resist the pressure but move with the crowd. Try to head away from the crowd when the crowd gives in. Ask help from the people around you if needed.
Like on all big festivals, crowd surfing is also prohibited at Ruisrock. It’s only for your safety folks! Climbing on your friend’s shoulders is also forbidden.
