Is this trail dog-friendly?

Dogs are generally allowed on a leash on the main trails within the Hazel Wolf Wetlands Preserve and Soaring Eagle Regional Park.

Please observe all posted signage regarding pet restrictions.

The terrain is generally considered easy, with a mostly level path and minimal elevation gain. You'll walk through mature cedar groves and lush ferns, with sections that hug the wetland's shoreline. There are boardwalks over marshy areas and a sturdy bridge crossing Laughing Jacobs Creek. Some parts of Ann's Trail may have narrow paths and short, steep sections, and can be muddy after heavy rain.

What kind of wildlife can I expect to see?

The preserve is rich in wildlife. You can expect to see various bird species such as mergansers, eagles, ducks, geese, red-winged blackbirds, and even great-horned owls. Beaver activity is a highlight, with visible beaver dams and lodges. Observation decks provide opportunities to scan the reeds and open water for birds and small mammals.

Does this loop connect to other trails or parks?

This interconnectedness allows for extended explorations and customized routes. The route itself utilizes sections of Ann's Walkway, Ann’s Walking Trail, and the Hazel Wolf Wetlands Access Trail.

The preserve itself is named in honor of Hazel Wolf, a dedicated social and environmental activist.

Is this trail suitable for families or beginners?

The mostly level path and minimal elevation gain contribute to its easy difficulty. However, be mindful that some sections of Ann's Trail can be narrow or slightly steep, and muddy after rain.

Are there any specific considerations for hiking Ann's Trail within the preserve?

Ann's Trail, which directly encircles the main wetland, offers a close-up view of the ecosystem. However, be aware that dogs are generally prohibited on this specific trail to protect wildlife.
