Access to the campground is via a 2.5 mile long single lane dirt road. There are a few small wider spots to squeeze past oncoming traffic, but locals tend to travel fast, so be vigilant.
We towed our 30 foot bumper pull behind our full size truck (49 feet tip to tail) and made it but this is right at the limits for maneuvering. There are several sites that will fit a 30 foot trailer. 35 feet seems like a stretch to me, but proceed at your own risk. There is a loop to turn around at the end of the campground. Scout out your site on foot and create a plan before pulling in. You may wish to travel around the loop one direction or another depending on your chosen site.
The sites are pretty well isolated and with the creek flowing fast, the background noise easily washed away the sounds of other campers.
No reception to cell service and limited view of the sky with rising mountains on either side. If seclusion, nature, fishing and camping up against a mountain surrounded by vegetation is your goal, you've found your destination!
We stayed one night but would have happily stayed longer. There is a general store, laundromat and saloon in Kingston but hours may vary.
