Tibbetts Mountain near the small town of Pashastin in Central Washington is one of my favorite early season SOTA destinations. Great views from the summit of the Enchantments and Stuart Ranges.
There are 3 ways to reach the summit; hike the trail (about 3 miles each way), hike the road (about 4 miles each way) or drive the rough narrow forest service road to within a half mile of the summit, then hike the last 1/2 mile with a few hundred feet of elevation gain. Google maps directions will take you to the summit, or within the last 1/2 mile of the summit.
