A short tunnel along Discovery Park's loop trail.
Discovery Park, Seattle
In the heart of Seattle, kids can choose from several miles of trails through different habitats at phenomenal Discovery Park. This urban nature reserve is accessible in all seasons and in all weather, and will satisfy your need for green trees, birdsong and fresh air.
Favorite trails: Park at the east parking lot, where the Environmental Learning Center is located, and start on the 2.8-mile loop trail. This loop ambles through the woods, along bluffs with stunning views and through meadows; there's even a sandy area where kids can dig. Try the whole loop, or just do an out and back. From the north parking lot (where Daybreak Star Cultural Center is located), you can walk the short Wolf Tree Nature Trail.
Indoor options: Hop into the Environmental Learning Center to escape the cold and play with the hands-on exhibits, which include a huge collection of wildlife puppets. Kids can learn about the forest and the seashore. There are also restrooms and a drinking fountain.
Bonus fun: Discovery Park updated its playground a few years ago and it's fantastic; find it a short walk south of the Environmental Learning Center.
