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


2015 promises to be an exciting year for us as opportunities for learning and new programs beckon! We are looking forward to the transitions through the seasons, from walks in winter landscapes to spring scouting for Amphibians, Woodcock and much more.

Our ability to do what we do depends on having  places in our community and the region where nature can flourish, and that offer visual and physical access to people. Come explore areas in our neighborhoods — the Nature Center, Coogan Farm and beyond — that we share with wildlife in winter and spring. During our monthly Full Moon walks, Birding Fridays, Pequotsepos Hikers and other planned outings, we will introduce you to wonderful properties protected by Avalonia Land Conservancy, Groton Open Space Association, Stonington and Westerly land trusts as well as national wildlife refuges including Trustom Pond and Sachuest Point.

During the winter outings, we will look closely at tree architecture and buds, track animals, study lichen and mosses on rocks, watch kinglets and other tiny birds and appreciate how all these living things survive during cold weather. By March, the frozen dead will awaken as sap begins to move in trees, Mourning Cloak butterflies emerge from brush piles and Wood frogs start calling from vernal pools. New this spring, programs on gardening and composting will make use of our new outdoor classroom spaces at Coogan Farm!

Nature will inspire you to get up, get moving and spend time outside! Join us!
