Hike
Need to know: You will need the discover pass to park at the trailhead. You can get the day pass or the annual pass. Check the website for updates.
Mailbox Peak is near the Rattlesnake Mountain Scenic Area along the Interstate 90 corridor, 40 miles east of the city.
It is a startling, steep hike and has challenged the calf muscles of Seattle citizens and beyond for generations.
This brilliant display of trail work gains more than 4,000 feet of elevation in the 4.5 miles it takes to reach the summit.
This strenuous elevation gain leads many people to question their motives about halfway up.
