Padilla Bay National Estuarine Research Reserve

Eelgrass is not a seaweed but a true flowering plant that grows rooted in the mud of shallow, sheltered seas. In Padilla Bay it forms a dense, sprawling meadow that ranks among the largest on the entire Pacific Coast of the continent, a rare survival of a habitat that has been lost from many other bays.

That meadow is a nursery for the Salish Sea. Young salmon, Dungeness crab, herring, and countless other creatures shelter and feed among the blades, which also anchor the mud, soften storms, and pull carbon from the water. Protecting eelgrass is now central to the region's work to recover salmon and the health of Puget Sound.

The best way to feel the size of the bay is the Padilla Bay Shore Trail, a flat, gravel path that runs for a couple of miles along a dike between the farm fields and the water. It is easy walking or biking, open to all, and every step gives a broad view over the eelgrass flats and out to the islands.

The trail is a front-row seat for the tide. Come at high water and the bay is a shining sheet; come at low tide and the eelgrass and mudflats stretch out for what looks like miles, dotted with feeding birds. Either way the light off the water and the backdrop of the Cascades and the San Juans make it a quietly beautiful walk.

A short way up the shore, the Breazeale Interpretive Center is the reserve's window into the estuary. Its exhibits explain the Salish Sea and the eelgrass world, saltwater aquariums hold local sea life, and a hands-on touch tank lets kids meet sea stars, anemones, and crabs up close. It is free to visit.

The center is also the public face of a serious scientific mission. Padilla Bay is a National Estuarine Research Reserve, established in 1980 by the state of Washington and the federal government, and it is used year round for research, monitoring, and education aimed at keeping estuaries like this one healthy.

For birdwatchers, Padilla Bay is a destination. The mix of open water, eelgrass, and mudflat draws huge numbers of waterfowl and shorebirds, especially in the migration and winter months, when great rafts of ducks, brant geese, and dunlin gather over the flats and raptors hunt the edges.

The reserve pairs well with the Skagit Valley's other seasonal shows. In late winter and spring the nearby fields fill with snow geese, swans, and eventually the famous tulip and daffodil blooms, making this a corner of Washington worth a full unhurried day.
