mount si – one of the most popular hikes in washington state. just about a 45-min drive from seattle, it’s a close and good 8-mile round trip hike with all the characteristics of what makes the pacific northwest what it is. the shaded trail keeps you cool through the 4-mile incline. the rocky summit makes for a great lunch (with caution) on its stone stools. bring a light jacket or long-sleeve for the wind at the top!
