Summer Camp


Eco-Discovery Camp

Great Hollow’s weekly day camp offers children ages 5-12 unique and fun opportunities to forge lasting connections with the natural world on our 825-acre nature preserve in New Fairfield, CT. Our days are spent outdoors, exploring Great Hollow’s creeks, forests, meadows, and trails, learning about the critters that make this special place their home. Each weekly session includes science-based environmental education activities, live animal presentations, games, hikes, and daily time for self-directed play.

Weekly Session Themes for Knee-High Naturalists (5-8 year-olds):

Go with the Flow: June 21 – 25

Spend your week frolicking in the water of Great Hollow’s Quaker Brook! We’ll catch crayfish and other critters, go on stream walks, see beautiful waterfalls, and visit a real beaver lodge. We’ll be busy having so much fun that we won’t even realize we’re learning all about the water cycle, watersheds, and the importance of healthy stream ecosystems.

Topics covered: aquatic ecosystems; plant and animal adaptations; beavers as a keystone species and ecosystem engineer; water pollution; aquatic macroinvertebrates as biological indicators; natural history of crayfish; water cycle; watersheds; properties of mud; best management practices.

Arts and crafts activities: water pollution multi-media art; building a model beaver lodge; painting with watercolors; tie-dye


Creature Feature: June 28 – July 2

From fierce raptors and bears to scampering salamanders and insects, we’ll spend this week of camp exploring the wide range of wildlife at Great Hollow! Every day of the camp week will focus on a different group of animals, including reptiles, amphibians, birds, and bugs! We’ll learn all about where we can find these creatures, how they are all connected, and the many ways they contribute to a healthy ecosystem.

Topics covered: wildlife tracking, predator and prey relationships; adaptations; wildlife conservation; scientific inquiry; symbiotic relationships; parasitic relationships; mutualism; ecosystems and communities; species identification.

Arts and crafts activities: building a bug hotel; textured art canvases; creating clay feathers


Dig This!: July 19 – 23

Let’s dig into the past! Become archaeologists and geologists for the week and investigate New England’s rich cultural and ecological history. We will explore the landscape and get our hands dirty as we investigate different rocks, fossils, and go on our own excavation adventures! We will also learn how indigenous and colonial peoples interacted with the land, hear their stories, and even take a look at some authentic tools and artifacts from pre-colonial times.

Topics covered: Native American history, natural crafts, geology, archeology, New England prehistory, indigenous landscapes, colonial homesteading, traditional farming, survival skills, forest succession, land use changes over time.

Arts and crafts activities: digging for minerals; insects in amber soap; creating dreamcatchers; colonial crafting, basic basket weaving


Ultimate STEM Challenge: July 26 – 30

Think outside the box and test your engineering skills! Spend the week completing increasingly complex STEM (science, technology, engineering, and math) challenges related to the natural world. We’ll tackle a wide range of hands-on interdisciplinary topics: from building our own bird nests and boat races, to homemade solar technology. Will you live up to the challenge? Let’s find out together!

Topics covered: green technology, science; renewable energy; engineering; art; math; natural crafts; physics; design; simple machines; physics; direct and indirect observation; scientific inquiry; biomimicry.

Arts and crafts activities: building a bird’s nest; symmetry and mandalas; stone stacking; paper making; building a solar s’more’s oven


Trail Blazers: August 16 – 20

Do you have what it takes to make your way through the woods? This week, we’ll walk through the different steps required to find your way through the wilderness and survive in the forest. Learn how to use a map-and-compass, how to make shelter, find freshwater in the woods, and fish. As teams, we will complete mini challenges that will increase in difficulty, culminating in an ultimate test of wilderness survival skills at the end of the week!

Topics covered: navigation; topography; map-reading; survival; engineering; orienteering; edible plants; botany; team-building and interpersonal communication; health and fitness; celestial navigation.

Arts and crafts activities: map-making; pressed flowers and foliage; making a fishnet, constellation art, making a first-aid kit


Weekly Session Descriptions for Eco-Explorers (9-12 year-olds):

Water, water everywhere! Did you know over 70% of our planet is covered in water, but only 2.5% of that water is fresh? Let’s spend the week following the journey of freshwater around our planet! We’ll conduct experiments, create a 3D watershed, and explore Great Hollow’s own streams, creeks, and wetlands and discuss the many different creatures that call those habitats home.

Topics covered: pollinators; symbiotic relationships; pollinator conservation; gardening; composting; local foods; bio controls; plant identification; native vs. invasive species; best management practices; water conservation; local foods; health and nutrition; culinary arts; agriculture; resource management; sustainability.

Let’s spend the week answering these questions and more in our quest to become true Wildlife Warriors! From fierce birds of prey to docile deer, and secretive lynxes, we will explore the many different species that call Great Hollow home. Join us as we search for tracks in the woods, set up natural baits and lures, and try to spot some of these creatures in action!

Topics covered: wildlife; field investigations; conservation; predator-prey relationship; evolution; natural selection; adaptations; wildlife tracking; scientific inquiry; species identification; food webs; ecosystems and communities.

In this week of camp, we will spend time in our very own vegetable and pollinator gardens, making observations, collecting data, and doing some farming. We will learn all about the importance of bees, butterflies, and hummingbirds as we practice different farming and foraging practices. As the week goes on, we will design and install our very own STEM engineering projects for everyday use in the gardens!
