We just finished six nights at Emerald Lake State Park.  Camping at Vermont State parks is always top notch.  We had a lean-to site and good privacy from the sites around us.  There was plenty of room for our tent and screen tent.  Everyone was respectful and quiet, even on the weekend when it was busier.  Bathrooms were cleaned daily, showers were fine.  50 cents for 5 minutes and then extra time for each additional quarter.  Two bars of AT&T.  Manchester was an easy 10 minute drive away for provisioning, and we enjoyed a great hike to Lye Brook Falls (the trailhead was around a 20 minute drive).  We would definitely come here again.
