I'm no stranger to backpacking but this might be my longest excursion and my first trip to Zion National Park as well. I'm planning on backpacking the Southwest desert, then the Western Rim from Lee Pass to the main Zion canyon (52 miles), then the narrows, and finally the East Rim. All in all it's around a 150-160 mile hike that'll last 8-9 days. Any advice on what to bring besides the basics? My pack is 65L and has a base weight of 5.8 lbs.
Forgot to mention I'm going in mid-September.
