Make sure to stop and fill up the yellow tab and leave the top on your dash and pay respectively. Id suggest to buy an annual park pass and military gets the whole year for free!! See the visitor center for it and while ure at it if you have kids, every National Park has an activity book to earn hat badge and stickers as junior ranger. On this location day hikers no need to register. And for the group campers and with those outdoor enthusiast glamping there is a designated spot for yall and must register ahead! All other campers, pick your own rock and by far this is the spot that i will keep coming back! The sky was perfect, no moon and u can see some jupiters moon like IO with naked eye, this night i saw 4!! It was spectacular!! Take nothing but pictures leave nothing but footprints and bring nothing but memories!!
