8:00 AM at the Mailbox Peak TH

Take exit 34 from I-90. Head north on 468th Ave SE for approximately half a mile 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 and drive .3 miles. Take the turnoff to the trailhead on the right and continue a short distance to the parking lot.

I live in Tacoma near the clubhouse and I'm happy to carpool from here or along my way (SR-18).

We'll do this hike at a steady pace with minimal breaks.  We'll go up the old trail and consider going down the new trail.

If it is a nice day, we will linger at the top for a while.  Bring your favorite food and beverages.

This is a dog-friendly hike.  I bring my German Shepherd and other socialized dogs are welcome.
