Time in the forest sparks joy, curiosity, cooperation and wonder!

A Unique Outdoor Preschool Experience

The mission of the South Mountain Nature School is to provide children the guidance and resources to play and learn in the South Mountain Reservation with other children while experiencing the wonders and beauty of the natural world.

SMNS’s Nature Immersion curriculum is defined as “free time in nature, resulting in an intimate, deep and personal connection to the natural world.” Our classes promote social and emotional development, teach compassion, gentleness and sensitivity for each other and the natural world and empower children.
