Right now park entrance is free, you must take free bus to go beyond human history museum, the run every 10 mins...
Driving through costs you the entrance fee of 35$ like in every other national park. If you plan to visit more national parks in the us I recommend you buying the annual pass for 80$
There is parking by the entrance, however once you are in the park there is a free shuttle service that takes you near the trails you want to go then you are free to walk around, I found this the best bet since there isn't so much waiting around,but im pretty sure you can just drive through if you'd like!
Alright thank you guys
