Mailbox Peak by Mount Teneriffe and Mount Si perches over Middle Fork Snoqualmie and South Fork Snoqualmie River drainages. Sitting at its top is the well-known mailbox that sometimes transforms depending on the season’s decor. The less strenuous new trail has been in place since 2014.

The Preface
Mailbox Peak has become extremely popular throughout the years since our first trip a decade ago. While going through my old photos, I realized that it had been six years since we climbed the peak. So a revisit to the old stomping ground was in order.
Because of recent roadwork on Middle Fork Snoqualmie Road, I researched conditions last night to be sure. Then I came across a recent report from yesterday on Washington Trails Association (WTA). What great timing!

Mailbox Peak on the Old Trail
We drove to the Middle Fork Road closure by the snow berm and started hiking at 5:15 AM for the extra .75-mile walk to the old trailhead. En route, I noticed massive tracks since the recent heavy snowfall. Glad we didn’t need to carve out a path!
Yesterday’s report was spot on about not needing snowshoes on the trail. But I wore microspikes for traction to avoid sliding on the steep incline and sped things up significantly. Some people are great at keeping balance in the snow without gear, not me.

Summit Views
We broke out into the first clearing as colorful popcorn clouds strewed the morning sky. Then it slowly cleared up at the summit. Despite being 28 degrees, it felt much warmer without the wind. The sun came out 20 minutes later as we enjoyed the visit in solitude.
Mailbox Peak continues to be the vantage point to see the vast Snoqualmie River Valley. No view of Mount Rainier this time as clouds in South Cascades had devoured the volcano earlier. But everything else was still visible, including a bit of Glacier Peak.

Exciting via Mailbox Peak New Trail
Two men came up as we made our way down to the boulder field. Right then, I decided to check out the new trail from 2014 after our previous visit. I found the unmarked fork shortly after going back into the forest.
We found fresh snow in the upper trail, so snowshoes came in quite handy. Then I switched to microspikes on firmer snow for the lower two-mile hike back to the new trailhead. We met seven people en route, pretty quiet for a sunny Friday!

Thank you for your update on the Mailbox Peak!
I would like to know how the road condition to the Middle Fork road were.
Did it require 4-wheel drive?
I would appreciate if you let me know ASAP as I am planning to go to the Mailbox tomorrow.
Thank you,
Baram
Hi Baram,
The roads are free of snow until you get to the stop sign before turning left onto Middle Fork Road. The snow berm will prevent you from going any farther, so park before the berm and hike to the trailhead.
Enjoy!
GREAT – thank you!
Vow, The Mail box peak trail looks so different and beautiful in snow. I recently did mailbox peak thru new trail with my hubby and kid , all the snow was gone. The pics here are making me to think to do this hike in snow. Do check my post on hiking Mailbox peak.
Thank you,
