West Soda Peaks is a nice hike. Probably better when it's not raining.
Guy, N7UN has provided access info HERE. I just wanted to add a little to it.
From Portland take I-84 to Bridge of the Gods. Toll is $2.
Cross the bridge and turn right onto WA-14.
Travel to Wind River HWY and turn left.
Turn left onto Hemlock
Turn right onto Little Soda Springs Rd/Szydlo Rd
