There is a lot of country to see, and admire, in that 25 miles. We have routinely driven from Colter Bay, into the park and traveled most of the Park in one day. Yes, Flagg Ranch is at the southern end of the Park, but it's not really that bad. You can leave fairly early in the day, see and enjoy a loop and come back to the RV for a leisurely dinner and do the same thing the next day or for however many days you are in the Park. All those people who say it's so far to drive don't really understand that almost every mile of the Park is a great experience so why not enjoy it.
