For much of the route in the lower elevations, you'll be following a mix of one-and-two track trails (old roads). I recommend a map and compass, as it can get confusing.
From the car park, you'll find the beginning of the trail by walking through the corral with two green-colored gates. After about 1.5 miles, you'll arrive at a junction. An old road blocked by logs goes left. Stay to the right.
Eventually the trail meets up with a wider, smooth road/track. Turn right on this road.
You may lose the trail at some point. If so, you can catch the route again at an obvious "morainelike rock glacier" -- the trail is in the trees to your right.
Again, the trail may be hard to follow... just stay in the central portion of the drainage if in doubt.
The next junction is with the Trans-LaSal Trail (with a sign), heading off to the right. Stay left.
Later you'll pass by the road to Miner's Basin, going right. Again, stay left. In this area there are remnants of several old miners' cabins. You might also see a profusion of colorful and interesting mushrooms -- we did this hike in September and the area was surpisingly wet, practically a rain-forest.
The best route up to the summit starts in or next to a steep gully on your left very near the end of the road you're hiking on, and near the head of the drainage.
If you continue a short distance past the gully to the head of the drainage, you'll see a spring that has formed a small pond. You could camp in this area if you had to, but flat spots may be hard to come by. (You'll also notice a pass southwest of Waas, directly above the pond... not to be confused with the recommended route described in this review).
Go up the aforementioned gully (or the adjacent slopes), then make your way up to the pass northwest of Waas. This is by far the hardest part of the climb. It gets very steep in sections. Once on the ridgetop, you can pick up a faint trail that goes the last 1/2 mile and 700 vertical feet to the summit.
There are several really nifty rock-wall shelters on the summit. People say there are fantastic views as well (the summit was in a thick cloud when we arrived!).
