Welcome to the Denison Pequotsepos Nature Center

For nearly 70 years, we have provided visitors and the greater Mystic community the opportunity to experience nature first hand, whether it be on the 10 miles of trails on land owned by the Denison Homestead and Avalonia Land Conservancy, in our natural history museum, our Nature Store, or as part of one of our many programs. The creation of the Coogan Farm Nature and Heritage Center in 2013 has added additional layers of education, history, and ecology to our offerings.

Our mission is to inspire an understanding of the natural world and ourselves as part of it – past, present and future. It is our hope that through DPNC and Coogan Farm that we will help our visitors foster a personal environmental ethic.

Come with us and explore the wonders of our region


Our summer days have seen visitors from all over the country and all over the world, browsing our museum exhibits, hiking our trails, and sharing their experiences on social media!

Renovations to the Coogan Farmhouse and Barn are well underway, and we are busily outfitting the John E. Avery House and Welcome Center, kitchen, and classrooms so we can begin using these fabulous new spaces for programs, meetings, exhibits, workshops and more. We have an exciting vision for DPNC and how our expanded campus and facilities at Coogan will allow us to better serve our members and the public. It is a feeling that is hard to describe to watch every day as our vision for Coogan Farm becomes a reality.

October 2015 marks the beginning of a new fiscal year, and the Nature Center’s seventh decade.  We will be celebrating our 70th birthday throughout 2016, beginning in January!  We will celebrate what is old and what is new, our past and our future, while delivering engaging and meaningful programs that help deepen appreciation and understanding of nature.
