I stayed at this campground with my climbing partner for a couple of days after an extended climb of the nearby Mt. Logan. The campground offers usual amenities like running water and bathrooms, and is conveniently located about ten miniutes from the town of Winthrop. There is also a nearby crag that is excellent for top roping or sport leading.
I would be cautious around holidays and three day weekends if you like to avoid crowds :)
Beautiful location along the river. The shower house we used was very clean and had individual rooms for each shower and toilet.
Swimming pool, bike rentals, mining for gems, arrowheads and fossils; purchase from store, playground. Cabins are quieter than tent/RV sites. Very nicely maintained. Grass. Not much privacy and very busy bathroom.
