Sure, you can access it from the top. Instead of turning downhill off of the old logging road (as you would if going to the Incredible entrance), just continue to follow the old road around the mountain, past the original entrance. But this time of the year, the dirt road is usually closed just past the turnoff of Rocky Lane. So what you save in terms of elevation change, you make up for in distance walked. Kind of a six-of-one, half-dozen of the other situation.
