The guidebook says
this is a steep trail: believe it. The trail gains elevation by going straight up hillsides rather than by switchbacks. Begin climbing at the trailhed on an old logging road until you reach the trail in half a mile or so. Begin a nice, steady traverse along Johnson Ridge, which is forested but provides occasional views. At two miles it's time to climb Sunrise Mountain. It's straight up, then straight down and on to Scorpion Mountain (try not to think about having to re-climb Sunrise Mountain on the return trip!). Eventually your effort is rewarded as the trail breaks out into a glorious meadow that seems to reach to the sky. At the juncture with the trail that descends to Joan Lake, turn uphill and have lunch at the top. If it's a warm, sunny Saturday like this day, be prepared to be assaulted by bugs. The guidebook says it's four miles to Scorpion Mountain, but we made it in 90 minutes, so we're dubious of the length. It also says they you won't find many people, which is true. We saw only two parties (one camping atop Scorpion) and there's not room at the trailhed for many more vehicles.
