For several years now, our society has recognized forests as spaces for rest, healing, and education, and has been actively experiencing forests through hiking, forest healing experiences, forest therapy, prenatal education in the forest, and forest education.
This means that the forest has come closer to our lives.
Early childhood education institutions provide forest experience education by visiting forests once a month to three times a week, and some parents are increasingly choosing educational institutions or forest kindergartens that provide forest experience.
This phenomenon is because it is believed that the forest as a place promotes children's creativity, allows for natural character education, and helps promote healthy physical development.

Although books that convey forest experiences have been published in response to social changes, some of them contain content that is difficult to apply to infants and toddlers, such as not reflecting the developmental characteristics of infants and toddlers or being composed of content that conveys ecological knowledge of the forest.
Additionally, it is a reality that there is a shortage of books that stimulate the five senses of infants and toddlers, help develop physical, language, cognitive, social/emotional, and exploratory skills, and provide information related to forest experiences that take developmental characteristics into account.

While teaching in early childhood education settings and at universities, I had many doubts about whether educational activities in forests for young children were possible, to what extent they could be applied, and how the results could be measured.
My master's thesis, "The Effects of Mathematical Exploration Activities through Forest Experience on Young Children's Mathematical Problem-Solving Abilities and Attitudes toward Mathematics," led me to participate in the opening of the 'SK Forestry Co., Ltd. Supeai Forest Kindergarten', and after operating it for about four years, I realized the need for forest experience teaching materials that are easily accessible to everyone.

This book is based on the doctoral dissertation, “Development and Application Effects of an Integrated Forest Experience Education Program for Early Childhood Focused on Natural Objects” (2014), and is composed of content developed and applied to an early childhood forest experience education program suitable for the development of young children.
It is composed of theory and practice so that it can be used in universities or early childhood education institutions that provide forest experience education, and the practical part presents specific materials with various photos to make it easy to provide forest experience education.
I hope this will be helpful to many people who are implementing forest experience education for young children.
