If you really want to get the best xp, do monkey madness, or atleast up to the point where you have access to the tunnel. If you won't do that, the best place I can think of is the Chaos Tunnels, but even there the difference in xp is very big in comparison to the MM tunnel. It is worth it to get to the MM tunnel.
