This is a review of the four walk-in tent sites at Mistletoe State Park.  I personally stayed in #4 and had a look at the others. 

The best site is definitely #2 -- feet from the water, spacious, suitable for more than one tent or hammock (better for tents as it is mostly open, but there are places for hammocks along the edges). 

Site #4 is probably second best, better for a hammocks probably (which is what I had) as no great level ground. It is not right on the water but has it's own private path to the water(couple hundred feet to the water).

Sites #1 & #3 do not really have access to the water without climbing down something steeply dangerous or through thick trees.  (The water access from the other sites is right in the middle of those other sites so you couldn't really share that unless they are empty or occupied by friends.)  Still #1 is a pretty good site.  #3 is the least interesting and smallest, but still secluded -- I wouldn't call any of these bad.

None of these sites have groomed tent pads -- just gravelly ground.   They do each have a table, fire pit, and lantern pole.  #1 & #2 are best for tents.  There is good separation between all sites.  Sites #2 & #3 are within shouting distance of each other and you'd be able to see tents, etc at one from the other.  There is an outhouse between sites #1 & #2, and another another between sites #3 & #4.  It is a 5 minute (or so) walk to the real bathroom (which also has showers) back in the main campground.

Other than the lake itself at sites #2 & #4, I didn't see any dedicated water source for these sites.  (The lake is silty -- pre-filtering recommended if you are using a filter.)  So you'd have to bring in water or get it from the bathroom area or maybe from an empty RV site which all have spigots.  You'll have to pack out your trash, and there are definitely critters around that will get in your trash so it should be secured somehow.  (Hanging it from the lantern pole isn't good enough -- you'll wake up to find a hole in the bag and it strewn around, ask me how I know.)

Everything in the park was very clean and well-maintained, although when I was here in September (during the week), the whole place was basically deserted anyway.

The water access at sites #2 & #4 is nice but it is not a real beach -- it is all large rocks for the most part and they were very slippery even when dry so be careful.  The water level was also extremely low when I was there so some of those rocks are probably covered by water earlier in the year.
