Good to Know: snow-free winter hike, kid-friendly, bird-watching, historic
Located just a few miles from downtown Everett, Spencer Island sits in the heart of the Snohomish River Estuary, a wildlife rich ecosystem where salt and fresh waters mix. Surrounded by snaking sloughs, this 400-acre island offers a slew of scenic delights from glistening mudflats to glimpses of snow-capped peaks. And the bird watching is superb.
Start your hike by walking east .6 mile on gravel 4th Street passing Everett’s sewage treatment plant reaching the trailhead at the old Jackknife Bridge. Alternatively you can walk straight on the paved Riverfront Trail to reach the Jackknife Bridge. While this route is longer—1.4 miles, it is much more scenic and interesting.
Now hike across the historic bridge. The bridge spanned nearby Ebey Slough from 1914 to 1980. In 1993 it was moved here to Union Slough providing pedestrian access to Spencer Island. It is one of the last remaining bascule (counterweight drawbridge) bridges remaining in the country.
Upon stepping foot on the island, come to a junction. The trail left follows a levee north to open-to-hunting WA Fish and Wildlife land. It terminates in one mile at a breach. For the Spencer Island Loop follow the levee trail south. There’s a parallel boardwalk loop which you may want to walk when it is not flooded. In .2 mile, come to a junction with the Cross Island Levee Trail, your return. Continue right, soon arriving at a bridge, one of several spanning breaches in the levee. These breaches were intentionally made by land managers to allow much of the island to revert back to a tide-influenced wetland. Scan the reeds, cattails, and sedges for a myriad of waterfowl and songbirds. Enjoy too, the view east across the saturated flats to Mount Pilchuck and Three Fingers.
Continue hiking on the levee trail towards the southern tip of the island. Alders line the way with the occasional birch and spruce adding a little arboreal diversity. The way now turns north following alongside Steamboat Slough. Cross another breach bridge and then turn left onto the Cross Levee Trail traversing wetlands teeming with life. Watch for hawks, herons, harriers, widgeons, ruddy and wood ducks. Look too for bald eagles, river otters, coyotes, and deer. Reach a familiar junction-turn right and retrace your steps back to your vehicle.
