It's a 20 mile hike if you go from wire pass to Whitehouse campground. Leave cars at Whitehouse to make it a one way terck. Pretty much flat except for one place you have to climb down a rope on a 10 foot drop but it's not exposed at all so it is really easy. A couple of spots can be wet and muddy but the 2 times I have done it it wasn't bad. You can wash off the mud when you hit the creeks. It's really a cool hike.
