My favorite part of Marble creek is the low noise, low traffic and you can always find a spot open. A few of the sights are right on the water which is a nice perk. Most sites are nicely separate by trees and brush, and a few in the front are more open and close together, better for groups. You can spend the day floating in the river or swimming near the little shut-ins watering hole. Fire wood can be purchased about a mile up the road for fairly cheep.
Vault toilets are usually clean and not too buggy. It appears to not have any water taps though, so bring your own! The Ozark trail passes through the camp and you can hike this (or drive) up to Crane lake. There is also a day use area with picnic tables and is close to the water so you can get in and swim. We love to come here for the quiet, low key atmosphere.
This being my first experience with a first come first serve campground, I was nervous coming in as we arrived fairly late on a Friday night. To my pleasure, we found a campsite to ourselves. My boyfriend and I travel and camp together and like to find sites that are quiet and give you a sense that you're a lot further from the city then we are. We were happy with the spaciousness and the distance between the sites. A few of the first sites looked much closer together and would make a great place for a larger group. I believe we were at site 8 near the back of the road where it felt quietier. Unfortunately though the second night a group of young boy scouts camped right behind us in the large communal spot, which made for a very loud night and early morning. Other than that, we really enjoyed the space and proximity to trails including the Mina Sauk Falls. There is your standard bug covered vault toilet and a spigot for water at the front. The best part was a designated leveled area for tents that made sleeping so very comfortable. Would definitely return, just maybe would go furather from the large communal spot.
