There is only one host and they are located in the upper loop.
Firewood and ice available from the host.
Yes, there is garbage service available in both loops and in the day use area.
There are "gray water" disposals in multiple locations in both the upper and lower loops. There is also a RV dump station near the entrance which I forgot to get a picture of.
There is a very nice restroom/shower facility in the day use area also.
I find it hard to believe but this facility is not reservable according to reserveamerica.com.
