Forest preschool.

Forest preschool used to be a Scandinavian curiosity. In 2026 it is one of the fastest-growing strands of US early childhood, with several hundred programs running in city parks, on farms, and at the edges of state forests. The pitch is simple: small children spend almost the entire program day outside, in nearly all weather, exploring real terrain instead of a classroom.

It works well for the right family. It is also more demanding than parents sometimes expect. This guide covers what an actual forest preschool day looks like, the cost and licensing realities in the US, the safety questions worth asking, and how to tell whether your child is a fit.

What it is

A forest preschool is an early childhood program (usually for 3 to 6 year olds, sometimes extending to toddlers or kindergarten) where the children spend the majority of the day outdoors, in a natural environment, in almost all weather. The Scandinavian model that inspired the US programs — Denmark's skovbørnehave, Germany's Waldkindergarten — has been running for 70+ years.

The Natural Start Alliance counts more than 800 nature preschools and forest kindergartens in the US in 2024 (the most recent national count), up from around 25 in 2008. The growth is fastest in the Pacific Northwest, the Mountain West, New England, and the Mid-Atlantic, but every region of the country now has at least a handful.

What a day looks like

A typical schedule, 9 am to 3 pm, three to five days per week:

• Morning meeting at the "base camp" — a permanent shelter, yurt, or tarp on the program's site — with song, attendance, weather check, and the day's plan.
• Walk to the day's spot in the forest, on the farm, or along a trail. The destination often changes by day or week.
• Open exploration: digging, climbing, building shelters, watching insects, gathering materials, dramatic play in the woods.
• Lunch outside at a log or picnic site, with hot food brought from base camp in a thermos in winter.
• Quiet time, story, or rest, depending on age.
• Walk back to base camp for pick-up.

Children come in soaking, muddy, exhausted, and full of stories. Programs typically provide rubber boots and a rain suit; families usually buy a second pair to rotate.

What it costs

Cost varies more than in conventional preschool because licensing pathways are uneven. Many forest preschools run as part-day or part-week programs, not as licensed full-day daycare. National tuition runs roughly $800 to $1,800 per month for a five-day, half-day schedule; full-day programs (where available) run $1,400 to $2,800 per month. Higher-cost metros (Boston, Seattle, Portland, the Bay Area) run $1,800 to $3,200 per month.

Many families combine a forest preschool morning with conventional afternoon care at a licensed daycare, especially when both parents work full-time. The supply of full-day forest preschool is still thin in 2026; see the Portland, Seattle, and Denver hubs for cities where it is most common.

Licensing and safety

Forest preschools fall under a patchwork of state rules. Some states (Washington, Vermont, Oregon, Minnesota) have created outdoor preschool licensing pathways. Others license forest programs the same way as a center, which is sometimes impossible without a building footprint. Many programs operate as half-day "enrichment" or "nature school," which is regulated differently from daycare in most states.

When you tour, ask:

• Are you licensed by the state? Under what category?
• What is your staff-to-child ratio in the woods? (Good answer: 1:5 for 3 year olds, 1:7 for 4 to 5 year olds.)
• What is your weather policy? (Most run in everything except lightning, extreme heat, and air quality above an AQI threshold; ask for specifics.)
• How do you handle tick checks and what is your protocol for known exposures?
• What does your incident response look like in the field? Where is the nearest road?
• How do you communicate with parents during the day if you are off-grid?

Our broader tour questions list applies; the licensing and weather questions are forest-preschool specific.

What the research says

Outdoor preschool research is younger than Montessori or HighScope research, and the studies tend to be smaller. The current best-supported claims are: more time outdoors is associated with better motor development, fewer respiratory illnesses in some studies, and stronger social-emotional outcomes when teacher quality is held constant. Academic readiness outcomes are comparable to high-quality conventional preschool — not better, not worse, in the most rigorous comparisons.

The AAP has formally encouraged more outdoor and unstructured play time in early childhood. That is not the same as a randomized trial of forest preschool, but it is the direction the medical literature points.

Which children fit

• Children who play deeply outside and lose track of time in the yard.
• Children who hate worksheets and structured group instruction.
• Children whose families value daily physical activity and weather exposure.
• Children with sensory regulation challenges — many do well in the predictability of natural environments, but some struggle with cold, wet, or bug exposure. Tour first.

Children who are anxious about new environments often need a longer phase-in; reputable forest programs build that in. Children with severe allergies to insect stings or pollen need a careful medical plan that the program can accommodate.

Where it might not fit

If your work hours require full 7 am to 6 pm care, forest preschool alone usually does not cover the day. If your child needs a tightly structured academic onramp before kindergarten and you do not have the bandwidth to add that at home, a conventional play-based or HighScope program may be a better single solution. And if you live in a metro where licensed full-day forest preschool does not exist yet, the combo schedule (forest morning + center afternoon) is the realistic version.

Bottom line

Forest preschool is a serious, well-developed model with European roots and a growing US footprint. It is best for children who are physically active, sensory-flexible, and ready to be outside in real weather. The biggest practical question is whether the program offers full-day care or whether you will need to pair it with afternoon care at a licensed center.
