SE643 - Gonge River StonesThe river stones are inspired by stepping stones in a river with each side of the triangle increasing in steepness and difficulty. The purpose is to jump from stone to stone without touching the floor you can vary the position of the stones to create more challenging paths for children. Each stone has a rubber rim on the base to prevent them from slipping and to protect indoor floor areas. The River Stones provide challenging, active, imaginative fun
