Cofrin Arboretum

The Cofrin Arboretum stands out due to its diverse ecosystems, serving as a living laboratory for UW-Green Bay's "Eco U®" ethos. It encompasses restored prairies, ancient woodlands, wetlands, and is uniquely situated on the Niagara Escarpment, a significant geological feature. This creates varied habitats, including ancient white cedar trees over 900 years old, and supports an exceptional array of wildlife, making it a blend of recreation, education, and conservation.

Yes, dogs are generally welcome on the trails at Cofrin Arboretum. However, they must be kept on a leash at all times to protect the diverse wildlife and plant species, and to ensure a pleasant experience for all visitors. Please remember to clean up after your pet.

Beyond general hiking, families can enjoy wildlife spotting, with opportunities to see white-tailed deer, red foxes, and various bird species. The interpretive signs and kiosks with QR codes offer educational insights into the ecosystems, making walks engaging for children. The Paul Sager Tract, with its ponds, is a good spot for observing aquatic life and green herons. The varied terrain also allows for gentle strolls suitable for younger children.

The Cofrin Arboretum features a mix of trail types. While some trails are natural forest paths, there are also asphalt and crusher dust trails that are generally more accessible for wheelchairs and strollers. It's advisable to check a current trail map or contact the university for specific recommendations on the most accessible routes, as conditions can vary.

The Arboretum is home to approximately 45 mammal species and over 200 resident and migratory bird species. You might spot white-tailed deer, red foxes, sandhill cranes, red-tailed hawks, and various grassland songbirds. The Paul Sager Tract is known for green herons. For the best viewing, visit during dawn or dusk, move quietly, and bring binoculars. The Arboretum's proximity to the Bay Beach Wildlife Sanctuary also encourages wildlife movement through the area.

The Arboretum offers over 7 miles of trails with varied terrain, ranging from relatively flat and wide paths (asphalt and crusher dust) to more natural, narrower forest trails with some elevation changes, particularly near the Niagara Escarpment. Most trails are considered easy to moderate, suitable for a wide range of fitness levels. Appropriate footwear is recommended, especially after rain or during winter.

Beyond the main loop, consider exploring the specific ecological areas. The Keith White Prairie offers a unique experience with its native grasses and wildflowers, especially vibrant in summer. The Paul Sager Tract, with its natural springs and ponds, is a tranquil spot often overlooked. For a geological marvel, seek out the ancient white cedar trees clinging to the Niagara Escarpment, some of which are over 900 years old and thrive in unique microenvironments.

The Cofrin Arboretum remains a beautiful destination in winter. When snow conditions allow, the trails are popular for cross-country skiing and snowshoeing. The quiet, snow-covered landscapes offer a peaceful escape and unique opportunities for winter wildlife tracking and photography. Always check local conditions before heading out for winter sports.

As the Arboretum is located on the University of Wisconsin-Green Bay campus, there are limited direct amenities within the immediate vicinity. However, Green Bay offers a wide range of restaurants, cafes, and accommodation options just a short drive away. You'll find various dining choices and hotels in the city center and surrounding areas to suit different preferences and budgets.

Yes, the Arboretum is well-suited for circular routes. The main trail that encircles the university campus is approximately 4.7 miles (7.5 km) and provides a comprehensive tour. Many smaller loops and interconnected paths allow hikers and cyclists to create shorter or longer circular routes, exploring specific areas like Mahon Woods or the Keith White Prairie, with lengths varying from 1 to 3 miles.

While the Cofrin Arboretum is generally not as crowded as some larger parks, it can see more visitors during peak weekend afternoons, especially in pleasant weather. To enjoy a more serene experience and potentially spot more wildlife, consider visiting early in the morning or later in the afternoon, closer to sunset. Weekdays are typically less busy than weekends.
