South Puyallup to Klapatche is a scenic section along the western portion of the Wonderland Trail. But for hikers who don't want to make the 93-mile trek around the mountain, the section can be reached via a shorter out-and-back or loop starting from the Westside Road.
The out-and-back hike starts from the Westside Road trailhead and follows the decommissioned roadbed for roughly 3.5 miles before reaching the old South Puyallup trailhead. The South Puyallup trail heads east toward the mountain, climbing slightly uphill as you ramble along the river for 2 more miles before reaching the junction with the Wonderland Trail. There is a permitted campsite here for backpackers who want to rest before tackling the upcoming hill.
Take a left at the Wonderland Trail junction to start your 2.2 ascent out from the river valley and up toward Klapatche Park. Continue north to find incredible views of Rainier and stop at the large Saint Andrews Lake and eventually the smaller Aurora Lake which serves as a great turn around point.
