This Spacious local park has amenities for sports and several forested multi-use trails for hiking and biking. Be aware that these trails are packed dirt and are designed more as light mountain biking trails.

East on Sunset Park is a small but dense network of mountain biking trails with features for a wide range of ability levels. Just be sure to keep an eye out for people who might be walking on the trails.

This small park sits right on top of the bridge, with a privillege view of the river, the bridge and the mountains in the background. Worth taking a break to sit in one of the benches just to enjoy the view.

Meandering climbing street that connects Lake Washington to the Arboretum - Definitely a beautiful stretch of the Lake Washington loop.

Mmmm... The view. Worth a 5-minute pause for a drink of water and to catch your breath after the climb up the hill (both ways).

It's amazing how peaceful and close to nature this little park is - we even saw a beaver swimming in the lake, not to mention lots of birds and rabbits.

This section of the Lake to Lake Trail stays on the edge of the Mercer Slough Nature Park property. The trail is a popular gravel commuter trail and is utilized in a few different group rides and races in Bellevue.
