I'm pretty sure there is nothing below 5.11 at China Bend. Almost all of the routes are 12s and 13s.
It's a long drive, when there are better choices in town. If you like moderate sport (5.8 to 5.11s), Post Falls, in Quemlin Park, is the place to be. There are just tons of good quality sport climbs on nice granite over there. Another place to visit in Dishman. A small place, but it has the best quality rock in the area. Most of the routes are 11s. There is a 5.8, 2 9s, and a 10a over there too. The ratings are very stiff old school at Dishman. The route Chicken Spread (5.9) is the hardest 5.9 I've ever done.
Another spot that is very popular in town is Deep Creek. The rock is fractured angular basalt. The walls are overhanging with lots of stuff to pinch. I don't particularly care for the rock type, but the gym crowd loves it.
