15–25 minutes from central Seattle

Mercer
Island

A calm, green half-day: lakefront parks, forest walks, playgrounds and almost no tourist crowds. Here’s the short list worth deciding between.

The quick verdict

Go for the parks,
not sightseeing.

Mercer Island is a local reset between Seattle and Bellevue, not a destination packed with attractions. For most families, Luther Burbank is the clear winner. Add Dragon Park for younger kids or Pioneer Park if everyone wants a shaded walk.

Pick by mood
