Mailbox Peak- The Hike Every Seattleite Must Do
Mailbox Peak, 4,822 feet
If you mention that you are a hiker and you live in the Seattle area, everyone will assume you spend your weekends climbing Mailbox Peak. Seattle’s most well known hike is also considered one of the most brutal. With a choice of two trails, you can follow the steep old trail or the longer, yet less painful new trail. Or, if you’re like me and you have to see it all, you’ll just combine them both into a loop and call it done.
Mailbox Peak is so named for the mailbox that marks the summit at 4,822 feet. The true history of the mailbox is largely unknown and rich in folklore. I’ve found my favorite to be:
The history of Mailbox Peak dates back to the '60s when a postman named Carl Heine was working as the director of Valley Camp, a Lutheran retreat near the base of the mountain. He had built a mailbox at the top, and challenged the youth to climb the summit behind the camp's facility. To prove that they actually made it, he hid a notebook inside for them to sign. - Only in Your State
While reaching the mailbox for a photo beside it is every Seattleites goal, the true reward is the incredible 360 degree views. On clear days, you can see all the way past the city to the Olympic Mountains, Mount Baker, and Mount Rainier. We were lucky enough to receive a day as perfect as this.

Why Mailbox Peak is a Seattle Hiking Essential:
Iconic Seattle Hike: Mailbox Peak is synonymous with hiking in the Seattle area, a true local classic.
Challenging Workout: Both the Old and New Trails provide a significant physical challenge, perfect for building endurance and leg strength.
Spectacular 360° Views: From the summit, you'll be rewarded with breathtaking vistas of the Cascade Mountains, including stunning perspectives of Mount Rainier, the Olympic Mountains, and Mount Baker on clear days.
The Enigmatic Mailbox: The summit features a real mailbox, adding a unique and quirky element to your accomplishment. Hikers often leave notes and small tokens, contributing to its local lore.
Choosing Your Ascent: Old Trail vs. New Trail
Mailbox Peak offers two distinct paths to the summit, catering to different preferences and fitness levels:
Mailbox Peak Old Trail: This is the original, direct route. It's shorter in distance (approximately 5.4 miles roundtrip) but incredibly steep, with a relentless 4,000-foot elevation gain. Expect a rugged, unmaintained path with significant roots, rocks, and potential for slippery conditions. This trail is best suited for experienced and very fit hikers seeking a demanding ascent.
Mailbox Peak New Trail: Built for sustainability, the new trail offers a longer and more gradual climb. It's approximately 11.2 miles roundtrip with the same 4,000-foot elevation gain, achieved through a series of switchbacks. While still strenuous, it's generally considered more accessible for a wider range of hikers and is easier on the knees for the descent.
We opted for a challenging loop, ascending via the steeper Old Trail and descending via the more forgiving New Trail.
Hiking Mailbox Peak is a demanding yet incredibly rewarding experience for any outdoor enthusiast in the Seattle area. Whatever route you choose, the sense of accomplishment and the unforgettable panoramic views from the summit are well worth the effort. Load your pack with camera gear, respect the mountain, and get ready to conquer this iconic Seattle hike!
