Tin Hat through to Lewis Lake: The longest 9 kilometers in the world. This section of trail is deceptive. By the map it's barely 10 kilometers, but it feels oh-so-much longer. It does have three remarkably steep sections near the top and, with all the switchbacks and elevation changes, the hiker might seriously want to consider overnighting at Lewis Lake or thereabouts. Your dogs will be barking. I have issues with this trail: it's breathtaking in just so many ways, but I sure wish I was not completely spent when I get to the end of the hike. I usually do this as a "there and back" hike, starting above Lewis Lake on the access road there, climbing to the hut and then reversing my steps. I admit that it's a bit of a cop-out to stop at the hut, but by the time I get over that last hill and see the sky-scraper out-house, I'm pretty much done with hills. I have been to the summit several times; I can skip the summit when I am trying to cough up a lung.
