Hi 63,

As Steve mentions it is really wide open in that area (at least in the summer, without snow). I have not actually been to Lake 6, but based on where I "think" you will be camping I suggest the route shown here:

This route takes you by the stream between Lake 4 and Lake 3 on a well established trail.

You can turn right sooner if you are not going to camp at the north end of Lake 3 and cut some distance. Just stay left of Muir Lake, and "straight line" to Lake 6.

Take lots of pictures:-) Really a beautiful place.
