A short, steep and rough climb will get you to the summit of Slide Peak. This is a good second activation for those heading to Stormy Mountain, W7W/CH-132.

A good place to start is Twenty-Five Mile Creek State Park 20530 S Lakeshore Rd, Chelan, WA - it's not a bad place to stay either. From the park you go 0.4 miles west and then turn south onto paved Shady Pass Road and go 2.5 miles to veer left at a Y and head downhill.From here you'll be staying on the main track of Slide Ridge Road for 12.9 miles to the parking area. Don't let your GPS show you any shortcuts - the main track is mostly graveled and well graded. Still, the few rough sections are best navigated in a vehicle with high clearance. 

You can start hiking towards the summit from the parking area at 47.9119° -120.2778°. The route is a bermed road that looks a bit unpleasant as it gains 650 feet in about 0.6 miles.
