Beautiful site. Short trail down to the lake, approximately 100 yards. Right across from toilets. Quiet. Roomy site. Enough space for four or five tents.

{"text"=>"Great campground right next to the lake and close enough to yellowstone. The campsites are nicely spaced and have enough room for a 26ft camper and long bed truck to menuver into a back in site. This is truly God's country. It makes me want to move to Idaho.", "languageCode"=>"en"}
