A fun little route, the crux is near the middle. A good warm up though before starting on the 5.10's to the left. This route is the only crack on the wall, it's a few feet left of the tree that grows to the right of the wall.
Location
This area can be a little confusing for the first time, so bring a guide book there are a lot of boulders, brush, & slot canyons. But park on the road near the north end of the formation and follow the obvious climbers/partiers trail, it will fork stay to your right and head towards the rocks. Beethoven's wall is the last main area before turning the corner south. Once at the base there is quite a bit of room for belaying which is good because this is a popular area and can get a bit crowded, especially on weekends.
Protection
If memory serves me correctly this is a top rope only wall. There are a series of anchors dotting the top of the rock. A good place to take beginners.
This is a fun route, and definitely 5.7 from start to mid-point (a ramp to the right). If you want more of a challenge, go to the left about 2/3 of the way up and finish the top of the "Direct Route" - there are a couple of 5.9 moves ... feel around and you'll find a few bomber hand holds that you can't see from below.
