I booked 6 nights at The Jefferson County Lake & Campground in Rigby Idaho due to the location and the number of great day trips that could be launched from this location. What a wonderful surprise this place is. The lake is really nice with a 1.2 mile walking/biking trail around the lake. The trail runs right by the rear of my campsite and Barron loved walking the trail. The beach area has canoe rentals although I didn't use it. There is also a fast flowing river just behind my campsite. Each site has water and electric but no sewer. I suspect this is why you are limited to 6 night stays. Less than a half mile from the park entrance is Yellowstone Lakeside RV Park which has a dump station for $5. Easy in and out.
