With its unique setting and outstanding natural resources, Heirman Wildlife Preserve at Thomas' Eddy offers the perfect location for viewing wildlife, walking, picnicking, fishing, and discovering the beauty and wonders of nature.

This natural preserve encompasses within its boundaries vast open spaces, two pristine lakes, fragile wetlands, and an extensive river environment. Heirman Wildlife Preserve at Thomas' Eddy provides convenient fishing access to the Snohomish River.

Note: Dogs are not permitted at this park.


The hike is an easy, mostly flat, three-mile hike that protects undeveloped riverfront and important floodplain along the Snohomish River at Thomas' Eddy. Here the powerful river ripples and churns through a pair of tight hairpin turns, occasionally jumping its banks to create new channels and oxbow ponds. As you are hiking, watch for waterfowl, such as ducks and swans. Take in views of the marshy meadows and Lord Hill rising above the river. Pack a picnic lunch, water, and a camera, but leave the dogs at home as they are prohibited in the preserve.

Park History

Dave Beck, Jr., a former Teamsters Union president, operated a gravel mining operation along the river. The site was purchased by the Palzer family and used for raising livestock and agriculture.

When the site was to be subdivided and sold for housing, the Snohomish Sportsmen's Association, led by Bob Heirman, led a campaign to preserve public access to one of the most popular steelhead fishing spots on the river. The Parks Department worked with the association to acquire the property.

Funding for the Bob Heirman Park at Thomas’ Eddy was provided by the Recreation and Conservation Office (RCO).  The primary intent of the 429 acre grant funded park is to provide fishing and river boating recreational access in an environmentally responsible manner.  Boaters that access the river from the new Snohomish Launch, High Bridge, Lewis Street or Langus Park are encouraged to take advantage of 3 miles of publicly owned shoreline for fishing, swimming, picnicking, and upland trail exploration.  Please note, river access is by boat only (no road access).  In order to preserve access to Crab Bar, please respect the adjacent private property.
