Heading out to Zion NP in early October. A friend and I are planning to do the Zion Traverse from North to South. He has already made the reservations.
Day 1: Lee Pass TH to La Verkin Creek near Kolob Arch Trail
Day 2: Hop Valley Trail to somewhere on the Wildcat Canyon Trail
Day 3: Wildcat Canyon Trail to West Rim Trail, camping near Potato Hollow
Day 4: West Rim Trail to the heart of Zion Canyon
Not being familiar with Zion, I am very concerned about water sources. The NPS website shows some seasonal water sources in those sections. Much of this depends on how much it rains up there. Being we will be doing ~12-15mi days, about how much water should we plan on carrying? 2l? 4l?
Just for fun: my gearlist for this trip is on my profile.
Any thoughts or experiences regarding water and this trip in general would be much appreciated. Due to a variety of factors, this trip will be my only big adventure this year so hopefully it is worth it.
