An interactive lunar map 'Quickmap' is available at: http://target.lroc.asu.edu/q3/ The controls open from a 'stack of papers' icon on the left and the zoom control is in the top left corner.
Zoom right in and spacecraft can be seen. This shows the landing stage of an Apollo mission and (below the red lines) trails left by astronauts exploring the surface.
I found this one myself but you can see all of them at: http://www.lroc.asu.edu/featured_sites/
