Nature-based preschool.

"Nature-based preschool" is a wider tent than forest preschool. It covers programs that center the natural world but still meet in a classroom for part of the day, programs that operate on a farm or a nature center campus, and programs that simply put outdoor time at the center of a conventional preschool rhythm. For most US families who like the idea of an outdoor-leaning preschool, this is the more practical category.

What it is

A nature-based preschool is an early childhood program (typically ages 3 to 5, sometimes including 2 year olds and kindergarten) where the natural world is the curriculum's center of gravity. The day balances meaningful outdoor time with a traditional indoor classroom space, materials that come from the natural world, and a play-based or emergent approach to learning.

In contrast to a forest preschool, a nature-based preschool usually has a regular classroom building, runs in any weather but retreats indoors during the hardest parts of the day, and is more often licensed as full-day daycare. The Natural Start Alliance directory counted more than 800 nature-based and forest preschools in the US in 2024.

Nature-based vs forest preschool, in practice

A typical day

A nature-based preschool day often looks like this:

• Indoor morning meeting and small-group activity around a current investigation (seeds, snow, beetles).
• Two-hour outdoor block on the campus, in a wooded area, garden, or pond, with teacher-supported exploration.
• Outdoor or indoor lunch.
• Rest or quiet time in the classroom.
• Second outdoor block in the afternoon.
• Indoor wind-down with story or art before pickup.

Materials brought inside often reflect what was found outside that day: a found stick becomes a measurement tool; an acorn collection becomes a counting set. The curriculum is usually emergent (see our emergent curriculum explainer) and pulls in the developmental domains a state preschool standard would expect.

What it costs

Nature-based preschool tuition typically tracks the higher end of conventional preschool in the same metro. National full-day tuition runs roughly $1,000 to $2,400 per month, with high-cost metros (San Francisco, Boston, Seattle, DC, New York) running $1,800 to $3,400 per month and lower-cost regions $700 to $1,400 per month. A handful of nature-based programs run as part-day or three-day-week schedules and price proportionally lower.

Several state preschool programs and public school districts now include nature-based pre-K classrooms (Maryland, Minnesota, Vermont, Washington). Those are usually free for eligible families. For a city-specific read on supply — for example, Portland, Minneapolis, or Denver — start with the city hub.

What good ones do well

• Outdoor time as the rule, not the reward. The schedule guarantees two to four hours outside every day except in named exceptions (lightning, AQI, extreme heat).
• Trained staff. Lead teachers usually have a background in early childhood plus environmental education or outdoor leadership. Ask how often the staff trains on tick checks, weather thresholds, and outdoor first aid.
• Real gear policy. Programs that take outdoor time seriously have a clear required-gear list and often supply rain suits and boots.
• Documentation that travels. Children's outdoor investigations make their way onto walls indoors — photos, drawings, found objects, transcribed conversations. This is the visible sign that the outdoor work is being taken seriously.
• Honest weather policy. The director can tell you the exact AQI, lightning, and heat thresholds at which the day moves indoors.

Questions to ask on a tour

• How many hours per day do children spend outdoors, in the typical week?
• What is your weather policy — specifically, AQI, lightning distance, heat index, cold thresholds?
• Tell me about a project that started outside and made it into the classroom recently.
• What is the ratio when you are out on the campus or in the woods?
• What is your protocol for tick checks, bee stings, allergies, and wet clothes?
• Are you licensed by the state as a full-day program?

What the research says

Outdoor and nature-based preschool research is younger and smaller than the long-tail research on HighScope or Montessori. The strongest supported findings: children in nature-based programs have comparable or better motor and social-emotional outcomes than peers in conventional preschool, similar early literacy and numeracy outcomes when teacher quality is matched, and modestly better attention and self-regulation outcomes in several studies. The American Academy of Pediatrics endorses more unstructured outdoor play in early childhood.

For most families the research is not the deciding factor. The deciding factors are usually the daily rhythm and whether your child lights up outside.

Which children fit

• Children who play deepest outdoors and seem flat indoors.
• Children who learn through their bodies as much as their words.
• Families who want outdoor focus but cannot make a half-day forest preschool schedule work alongside full-time jobs.
• Children with sensory regulation differences who do well with predictable indoor-outdoor rhythm. (Some struggle with the unpredictability of weather; tour first.)

Bottom line

Nature-based preschool puts the outdoors at the center of the day without giving up the classroom. It is often licensed as full-day daycare, easier to schedule than a true forest preschool, and growing fast in 2026. Tour with the weather policy and ratio questions ready, and look for documentation of children's outdoor work indoors.
