Hazel wolf wetlands preserve

The Hazel Wolf Wetlands Preserve is one of the most pristine wetland-based wildlife refuges in King County. The preserve’s 116 acres were preserved in 1995, thanks to an innovative partnership of residents, progressive corporations and county governments.
The Hazel Wolf Wetlands contain several different wetland and forest habitats. This varied landscape supports many of our area’s beautiful and sensitive plants and wildlife. The wetlands are also key to a network of protected habitats stretching from the Issaquah Alps to Lake Sammamish. These wetlands help control the quality and quantity of water flowing through Beaver Lake all the way to Lake Sammamish.
For more than three decades our community was invigorated by the tenacious spirit and foresight of grassroots advocate, Hazel Wolf. After retiring from her first career, Hazel worked as a leader of collaborative, cooperative environmental and community projects. To honor Hazel’s 100th birthday, Forterra (then Cascade Land Conservancy) and citizens of King County dedicated this nature preserve as The Hazel Wolf Wetlands.

a network of protected habitats

In 1995, Quadrant and Taiyo American corporations donated the iconic 116 acre preserve to the Forterra (then Cascade Land Conservancy). The process began when neighbors recognized these as some of the highest quality wetlands in the region and wanted to protect them from a rapidly changing landscape. King County later purchased a conservation easement, ensuring permanent protection of the wetlands.
Today the land continues to be owned and stewarded by Forterra. It is open to the public offering trails which lace though Hazel Wolf Wetland’s rich vegetation, diverse species and even a beaver dam. After fishing at Beaver Lake, it is not uncommon to see osprey and bald eagles rooting in large trees. On the water, you may see hooded mergansers, pied-billed grebes and wood ducks and in the forest, you may see pileated woodpeckers drum for insects, cedar waxwings forage, hummingbirds search for nectar and robins’ nest.
Please help up protect the wetlands by abiding by the preserve’s access and use rules:
  • Stay on trails and travel quietly
  • Keep all pets on a leash and remove pet waste
  • Motorized vehicles are not allowed on the trail
  • Do not light fires or fireworks
  • Do not create trails, build structures, post signs or litter
  • Leave all animals and plants undisturbed
  • Please keep in mind that pets are not allowed on Ann’s trail 


Securing Hazel Wolf Wetland’s 116 acres of wetland and forest habitat, complete with trails and viewing platform, in Sammamish was one of Forterra’s early and beloved projects back in 1995. You can explore the beautiful, flat trails of the wetlands yourself today.
