Gold Basin Campground is on the Mt Loop highway, in the Mount Baker- Snoqualmie National Forest.  It is stunning. I really love this area! This is a large campground with over 99 sites, due to flooding damages the sites are currently first come first served, but generally they are reservable. The sites are large but close together. There is a huge grass field with plenty of space to get a baseball or soft ball game going, maybe a soccer game. There are amazing showers and flush toilets! There are drinking water spigots, trash cans close to the sites. The river is gorgeous, so get a site along the river obviously! Wildlife viewing abound.
