About Us

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

SMNS follows The Cedarsong Way, which is an early childhood education model that offers a nature immersion curriculum. Nature immersion 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, instill confidence and foster independence.

SMNS is committed to the principle of equal opportunity in education and employment. SMNS does not discriminate against individuals on the basis of race, color, sex, sexual orientation, religion, disability, age, veteran status, ancestry, or national or ethic origin in the administration of its educational policies, admission policies, employment policies and other school administered programs and activities.

What We Do

Forest School classes take place in woodlands in all types of weather over an extended period of time so that children can develop a close connection with nature. During a SMNS class you will see children exploring the woods, running with butterfly nets, building forts, and digging in the dirt. Our students invent new games together, pick wildflowers, climb on fallen trees and much more. Time in the forest sparks joy, curiosity, cooperation and wonder!

SMNS provides students tools for free play such as buckets, shovels, magnifying lenses, butterfly nets, binoculars and musical instruments.

Our Activities

During our time in the forest any or all of the following activities are enjoyed:

  • climbing and balancing on fallen trees
  • digging in the dirt
  • creating nature-based art projects
  • recognizing patterns in nature
  • swinging from vines
  • identifying animals and plants
  • playing games
  • observing changes in the natural world around us

An essential part of the SMNS mission is promoting and teaching our students environmental stewardship. When possible we use sustainable materials for our projects, and we will always leave the forest as we found it.
