Welcome to Tohi, a family-run woodland camp and nature preserve! We are your hosts, Colin and Grace Touhill, the heart and hands behind this hidden sanctuary nestled deep in the Pennsylvania forest.

Tohi is more than just a destination — it’s a passion project, a conservation effort, and a life-long dream brought to life. With backgrounds in environmental science, outdoor leadership and a lifelong love of nature, we care for this forest with the hope of inspiring meaningful connection — with loved ones, with the land, and with every guest who comes to visit.

Before Tohi came under the care of our family, it was at risk of being cleared for development. But we saw something worth protecting. With its rich biodiversity and deep historical roots, we knew this forest was meant to be preserved and thoughtfully tended, with respect for its past and future.

Once the property of Robert Mullen—founder of Philadelphia’s historic Tun Tavern—and later the site of Girl Scouts of America programs, Tohi has long been a place of gathering, learning, celebration, and shared purpose. Throughout this land’s history, it has hosted camping trips, jamborees, volunteer efforts, leadership adventures, and heartfelt celebrations like weddings, badge ceremonies, and family reunions. Today, we carry that tradition forward with care, ensuring Tohi remains a place to gather, grow, and create lasting memories for generations to come.

Colin, an Eagle Scout and enthusiastic outdoor adventurer, brings a passion for hands-on stewardship and exploration. Grace, with her background in wildlife conservation (and a special love for native plants!), advises our sustainable forestry practices and environmental education efforts.

We both grew up exploring streams and building forts, falling in love with winding trails, leafy hideaways, and the freedom to run wild. Now with our first baby on the way, we're excited to raise the next generation with that same wide-eyed sense of wonder and barefoot freedom we came to love.
