In the game, the child unconsciously develops all his potentials. Playing in nature affects the child's intellectual, psychomotor, emotional and social areas of development. Nature provides the child with unlimited opportunities for free movement and exploration. Just as a child has a need to explore the world around him, he also has a need for artistic expression. In the first part of the paper, the importance of the natural environment and play in nature is theoretically addressed. The paper also emphasizes the role of the educator, who is a careful observer of the child's activities, and with his various roles contributes to the planning and shaping of further children's experiences. However, the educator is not the only one interacting with the child, that is why the child's social environment is also important. The backbone of this work is Land art, a direction of contemporary art that encourages artistic interventions within the natural environment, while using natural materials, mostly found in the place where the work of art is created. The second part of the paper presents research that was carried out in the DV "Sisak Stari", in the facilities "Bubamara" and "Pčelica", with children of different ages. We combined two children's needs - the need to explore the world around them and the need for artistic expression. We observed and researched how the natural environment affects children's artistic expression and to what extent creation in nature, with natural materials, stimulated children's imagination and creativity. The research part of the work ultimately showed that the children had not encountered Land art activities until now, and they encouraged them to express their imagination and creativity, which is visible in the moments when their original works were upgraded.
