We took the Stevens Canyon Road 10 miles up from the entrance to the Wonderland Trail and hopped on the trail for an out and back and then walked around the Box Canyon area on our return which is where we had parked the car. The Wonderland Trail goes all the way around the park, 97 miles, so you can hop on at various points.
We hit the trail about 7:30 and were so happy we did not wait any longer, it was pretty warm already. The high for the day in Packwood was 98!
The Stevens Canyon Road crosses over the Box Canyon of the Muddy Fork of the Cowlitz River:
