Colter Bay campground is very convenient in that it sits in the northern part of Grand Teton. In the spring especially, it will put you close to the bear action. There is a convenience store with gas pumps at the end of the road and Colter Bay village has laundry, showers, grocery store, restaurant, marina, and a small museum. The only issue I've had staying there is coming in late or after dark and having someone else take my campsite. That seems to be a common occurrence in many of the national park campgrounds. I car camp (sleep in the car) so I don't have a tent to set up. I've left lawn chairs before, but have had them stolen or ignored.
