Greek Creek Campground is a small 15 site campground in the Gallatin National Forest. The campground is located on both sides of U.S. Highway 191. The West portion of the campground has 6 sites and sits on the shore of the Gallatin River. The East portion has 9 sites. The campground is paved with gravel parking pads. Each side of the campground has ADA accessible vault toilets. Sites are$20 per night and all sites can be reserved so the chance of finding a spot available on the weekend will be difficult unless you have reserved a site. I was unable to find an available site and I arrived at the campground at 9am on a Friday morning. This is going to be a loud campground at nice with the busy U.S. Highway 191 running through the campground, so unless you are a sound sleeper you might just want to pass on this campground. All campsites are equipped with a picnic table and metal fire ring. Both sides have water and trash service, including recycling. The campground is nicely wooded with Fir, Spruce and Cottonwood trees. The Gallatin River is a popular Rafting and Kayaking location with numerous outfitters available, the river is also a popular fly fishing destination. If you enjoy hiking many trail heads are available in the area.
