GTNP & Yellowstone NP Camping

I think it depends on your priorities. We use Colter Bay campground, not the RV park, and dry camp. We then spend most of our time fishing on Jackson Lake, right next to Colter Bay campground. When we want, we get in the car and sightsee both Grand Teton and Yellowstone. It's about 45 miles, one hour, from Colter Bay to the south entrance to Yellowstone and there is a lot of scenery on the way there. Once there, there is a lot of scenery going to the loop you want to see that day. We generally go around Yellowstone Lake and up to Canyon then over to Norris, down to Old Faithful and back to the FW. We usually get up pretty early, 6:00 or so, have breakfast, make lunch and then we go. After doing the lower loop, we get back to the FW around 6:00 or a little later for a late dinner, remember it doesn't get dark until after 8:00 pm or later during the spring and summer. Then, if we want to do the tour again, we do the same thing, bypass as much as possible the lower loop and go to Norris, Mammoth and back over Dunraven and back to the FW. I'n not saying this is ideal for seeing either park, but that's basically what we do, and have done for over 20 years of taking our FW to Grant Teton. By the way, sightseeing around Grand Teton is terrific as well, especially early in the morning and later in the day. Also take the Moose/Wilson road to see the latest addition to the Park, Laurence Rockefeller Reserve, which has a nice visitor center and a great little hike to the old family compound at Phelps Lake. They have taken it back to nature, removing over 30 buildings and it is very hard to see any evidence the buildings were there. Grant Teton is a lot easier to sightsee in with fewer people and less mileage to see most of it.
