English Boom County Park is an all-season area that offers bird watching, beach combing, wildflowers and views of the Cascades. It is also a historical area with remnants of early logging operations for transporting logs by rail and water. There are picnic facilities and wheelchair-friendly boardwalks and a viewing platform. A short walk takes you through an estuary cut through with small channels. A small parking lot accommodates about ten vehicles which includes some spaces along the end of the road.
At the entrance there is a shelter with picnic tables and a kiosk with information about the history and the natural habitat. Starting there is a wheelchair ramp and viewing platform on the beach. From the parking lot a trail heads southeast through an estuary cut with channels that nourish the salt water with nutrients and minerals for salmon, smelt, herring, clams and crabs.
These creatures in-turn provide food for the eagles, kingfishers, herons and other waterfowl. The channels have movable wooden bridges but they may be missing at time due to high winter tides. Continuing on the trail which parallels the beach takes you to a larger channel at about 0.45 miles that has no bridge. This is the end of the trail.
Beyond here is the Davis Slough Heronry which is a thirty-one acre rookery off limits to hikers. This is where binoculars, a telescope or telephoto lens for your camera is useful as the great blue herons by the hundreds nest and feed. Also watch for eagles, hawks and kingfishers hunting in the area.
You can also walk on the beach but beware of the very slippery clay-like substance that makes up the shoreline as well as sand saturated with water that can come over the tops of boots. While on the beach or the trail the ever-present Cascade Mountains can be seen across Skagit Bay, most notably Mount Baker, Glacier Peak, Three Fingers and Mount Pilchuck.
The name comes from Edward G. English who was one of the founders of Mount Vernon and one of the leading timber magnates in the Northwest in the late nineteenth century. Timber that was harvested at his operations travelled by rail here and then assembled into log booms for water transport. The pilings used for tying up log booms that are still there and have been repurposed for bird house perches.
