Mailbox Peak Old Trail is an extremely tough 5-mile roundtrip hike. Once you make it to the summit, the view is simply incredible. 

Note this adventure covers the old route. For the updated route, check out Hike Mailbox Peak New Trail.

Take exit 34 from I-90. Head north on 468th Ave SE until the intersection with the SE Middle Fork Road. Turn right onto the Middle Fork Road. Follow SE Middle Fork Road 2.2 miles to the stop sign at the junction with SE Dorothy Lake Road. Head left onto SE Middle Fork Road. Take the turnoff to the trailhead on the right and continue a short distance to the parking lot.

The greatest reward is the joy of the effort itself and of digging deep within yourself to find the strength to conquer the mighty Mailbox and be able to place your name in the summit register. The register is contained – appropriately enough – in a mailbox someone installed at the top. The views and scenery along the way are few to none, mostly forest trekking. But once you break to the infamous Mailbox scramble the views of Rainier and the valley are UNREAL.

The way down is worse than the way up. Bring trekking poles. This is not an easy hike, it seems short but the elevation gain is 4200 ft of straight vertical trails. Put your name or a memorable note in the Mailbox at the top, there is a designated hiker who collects everything in the Mailbox and places it in the King County Library Archive :)

It is important to note that this adventure features the old Mailbox Peak Trail. The new trail is approximately 11 miles roundtrip. If you choose to hike the old trail, remember to follow the white diamonds (trees marked). The old and new trail meet approximately 1 mile from the peak. The last 1/2 mile gains about 1000 ft altitude, and is a light scramble to the actual mailbox.

Mailbox Peak Old Trail Reviews

The 360 degree views are amazing when you reach the peak. I took the old (unmaintained) trail up by following the white diamonds. This is about 4000 elevation in 2.5 mi. The old trail then meets the new and the final push to the mailbox begins. With 1/2 mile left, you will be challenged with a steep elevation gain of approximately 1000 ft. Come prepared. Bring Water and extra food. Trekking poles are a great help on the way down!

Start early and beat the crowds. With the new trail, there are lots of people at the top. The old trail is a great trainer for more serious peaks in the cascade. Recommend descending the new trail to save the knees.

Great training hike. Should only take a fit hiker 2 hours up with a 40lb pack. This year it is snow free...

Most avid hikers in the Seattle area have done this hike. Whether you do the old trail or new, it's not for those who rarely get out, unless you'll expect a bit of a spanking. Beautiful views of the Snoqualmie Valley if the day is clear.
