Mount Si

This mountain, being the most popular hiking destination in Washington State, needs little introduction. The trail provides an eight mile round trip climb to sweeping views of the surrounding natural areas, cities, working farms, and forests in this picturesque part of the Greenway.

This mountain may look like an impenetrable fortress of solid rock, but it is actually quite fragile. Every year thousands of hikers scramble to the top and the impact takes its toll on wildlife habitat. You can help keep this spectacular area in good condition by staying on the established trail and keeping pets on a leash. To view recent trip reports from the Washington Trail Association visit their website.
