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 Nature and Heritage Center at Coogan Farm 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.

The Nature Center and Coogan Farm: Take a walk through time


Welcome to Pequotsepos! With the recent acquisition of the 45-acre Coogan Farm linking the Nature Center to the Mystic River, this is an exciting time to visit and explore all we have to offer. You can experience the wildlife, culture and heritage of our region through trails, exhibits, programs and activities for all ages.

The Nature Center, located on Pequotsepos Road across from the Denison Homestead, connects across the Pequotsepos Brook to the Coogan Farm overlooking the Mystic River along Greenmanville Avenue. Our extensive trail system winds through woodlands and meadows, past ponds and historic stone walls, quarries and foundations: a greenway preserving history, nature and community connections, linking neighborhoods, schools, local attractions and businesses.

Here you can connect with nature through the seasons in restorative and peaceful surroundings, enjoy shade on a warm summer day, a cool spring breeze off the water, the smell of autumn leaves, or the quiet of a winter landscape. Listen for migrant and nesting warblers and songbirds, or visit with live owls and other raptors in outdoor flight enclosures.

Come on a full moon walk, or watch for fireflies and bats. Look for native wildflowers and colorful fungi in the forest, frogs and turtles in wetland areas, and butterflies and insects in fields and meadows. Our indoor exhibits help prepare you for what you may find outside!

We offer an exciting Summer Nature Camp program, a state-licensed preschool, regular walks, lectures and special activities for adults and families year-round—from beekeeping and bird-watching to tree identification and wreath-making. As we continue to develop programs and exhibits at Coogan Farm, you will also learn about the people and families that inhabited the land through the centuries. A visit to the Nature Center and Coogan Farm is like a walk through time while experiencing the present, a place where nature and history shape our future and every day is a new experience!
