Welcome to the Denison Pequotsepos Nature Center

For 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.

As the seasons change…


Here at Denison Pequotsepos/Coogan Farm Nature and Heritage Center we are in a new stage of organizational growth and development. We have high hopes for the future, an investment in the local community and beyond, reflecting the confidence and ambition of a competent, energetic and engaged board and staff.

As the seasons change, it is interesting to reflect on the growth and development of the Nature Center over the past seven decades. Like a caterpillar transforming the organic substance of a leaf into the juices and organs that eventually turn into a flying insect, DPNC has continued to transform its role to help connect sustainable tourism, healthy food production, recreation and history to nature and the environment.

With deep organizational roots and connections to our region’s founding families – Denisons, Gallups, Greenmans, Stillmans and others – we continue to expand on the importance of our heritage as an intrinsic part of the wild and cultural landscapes and natural ecosystems we cherish. We are about nature and so much more!
