Eagle Roost (originally Shady Acres) sits high on the river bank with gorgeous views of both upstream and downstream, including the "eagle tree" and Mt. Adams.  It has a mixture of sun and shade, all dependent on the time of day. 
River access is close when the water is lower. In the early season, when the river is still running higher, the only beach available is Big Beach, which can be reached by walking or driving.
Smaller sizes of vehicles can fit here easily, but larger trailers and big motorhomes may have some limitations.

This site would be a good combination with Rabbit Hollow for groups.
