Looking for a weekend destination? Try the SR 520 Trail!

Making plans for the weekend? Don’t forget to include a trip on the SR 520 Trail, which opened across Lake Washington last December! No matter the weather, the trail provides great views of the lake and its surroundings. For more information about how to access the trail or how we’ll extend the trail in the future, visit our new SR 520 Trail webpage. You’ll find maps, bicycle/pedestrian resources and more. In addition, our new SR 520 Trail Flickr album tells a pictorial history of the trail, from the start of construction to last December’s cross-lake opening. We hope to see you out on the trail!
