I have noticed that there are a few different pass types - a $12 one for individuals and a $25 pass for a car.
During the 6 days my family of four have inside YNP and GTNP, we will be spending 4 days driving ourselves and 2 days on organised wildlife tours.
The tours originate from Jackson and Gardiner, with the tour from Jackson being our first day entering either park. Neither tour includes park entry.
If we buy the $12 pass per person to use on the first tour, will these passes suffice when we drive into the park the next day? Or will we have to pay an added $25 for the car? Sorry, I'm a bit confused how it works.
Also, can the passes be bought from somewhere in the town of Jackson on the evening before, or even better, somewhere online?
Thanks so much for everyone's continued advice. You have all been so wonderful.
