I have camped there a few times. I do not personally think there is a better loop. I did find the southern end of the campground (not sure what loop it is) is next to the entrance into the park and the main road. Stay to the north of the camp ground. Less road noise and I think closer to the river
Ill be there on the 25th and 26th I'm thinking of this month. Sites 58-63 look nice, its hard to tell from the map where you can drive to? 74 72 71 and 68 looks like they are back in the grass and wouldnt work with RTT setup?
I looked at the BLM land, mainly Smithsonian Butte but I will have a 7-10 hour drive before arriving at camp for the night. I like the idea of not having to pack up my roof top tent and annex just to drive 30 mins to the park for the day. Also the showers at Zion Outfitter are a factor since I dont have a solar shower yet and will be dispersed camping the two previous days down there.
For anyone curious, there are still tons of sites available only being two weeks out. Most of the prime river spots are booked however. I plan on getting to the campground around check in time, setting up my RTT and annex and then heading to the Zion Outfitters and brewpub then heading on the shuttles into the park.
This will give me most of the afternoon and evening first day, and second day I will be able to wake up and head straight to the shuttle for another full day in the park! From there I will be heading to Valley of Fire the next morning.
