Hot Springs!
I love this place! 45 minutes away from Bozeman and you’re in the middle of a beautiful landscape. The camping is descent with some sites having hookups. When you’re camping it’s only and extra $3/day per person to go to the hot springs...normally $8/person. They have great food and a descent selection of beer/wine as well. They also have bands play at night on the weekends which is awesome!
