Wetland magic: Bellevue’s Mercer Slough
At 320 acres, Mercer Slough Nature Park is one of Bellevue’s largest parks. Its 7 miles of flat trails, which include several tot-friendly short loops, lead hikers through a verdant ecosystem of canals and wetlands — there is even a blueberry farm on the west side of the park. Look for red-winged blackbirds and duck species along the waterways, or downy woodpeckers and black-capped chickadees in the woods. The Environmental Education Center, a complex of classrooms and a visitor center, perches on the edge of the slough; kids will love the tree house, which they can climb via a ladder to peer into the tree canopy.
Activities: The slough’s education center offers a small assortment of displays and natural items to touch and see, and you can go on a self-guided scavenger hunt. Bellevue Parks offers free family nature walks here; search for keywords “Mercer Slough” on the registration page and sign up early.
Stream in: Lewis Creek Park, Bellevue
Tucked away in the hills of south Bellevue near Cougar Mountain, the lovely preserve of Lewis Creek Park protects the headwaters of Lewis Creek, attracting birds and wildlife — as well as little adventurers. A 1-mile loop trail makes for a perfect short hike for families, and there are also two connected playgrounds near the park’s visitor center.
Activities: Visit the spacious, light-filled Lewis Creek Park Visitor Center to thumb through nature books, look at casts of animal tracks or use a spotting scope.

Frogs and forts: Magnuson Park, Seattle
Seattle’s expansive Magnuson Park holds many draws for families. Definitely do not miss the wonderful Magnuson Children’s Garden among them. At the garden (located at the north end of the park, near the Junior League playground), kids can learn about composting, go on a scavenger hunt or even build a fort from a small pile of logs. Take a self-guided tour of the garden or explore the wider park. There’s a popular dog park, soccer fields and a network of flat trails that are perfect for strolling or low-key bicycling. Birds are abundant; in winter months, you might see bufflehead ducks or a great blue heron in the wetlands. In spring and summer, look for frogs and spectacular dragonflies.
