Norman is pretty much a single track. I can't quite figure out how someone could get lost on that. We hiked up to the helicopter pad, and a little past that, then retraced our steps back. It looked from where we stopped almost like the trail continued on all the way 'round the island.

I think including stops to admire the view and take some photos, we may have taken 40 minutes round trip. You can pretty much make it what you want.

Now that I think of it, you can pretty much make out the trails on the satellite image. Hopefully this link works: google map

It is quite the view looking down from the cliffs over the bay on the south side of the island.
