Although the state currently lists the campground as open, visiting there in mid-June I found that it looked essentially abandoned. There was no fee collection, the toilets were locked, and the fire ring in the site I chose apparently had no fires since last year, as it was covered in dried leaves. Other sites were similar. Nobody else camped there the night I stayed. Overall it was a slightly creepy experience.
That said, it's a lovely location with heavy foliage providing substantial privacy between sites, and several sites are adjacent to the creek (which was running a bit high and fast for decent fishing the night I was there). The sites were large, with picnic tables and fire rings at each one. The mosquito situation was about normal for that part of Alaska (bring bug dope). Water is available, but boil before using.
Not sure what the heck is going on with its status but I would guess it's pretty nice when it's being maintained. That said, I'm not sure I'll be back - it's about 40 miles from the Eagle Trail SRS, which is really nice.
