These Are the National Parks Requiring Reservations in 2023

"Muir Woods was the first NPS unit to implement a permanent reservation system in 2018, creating “a more enjoyable experience… by better fitting the capacity of visitors into the monument's limited space,” the park’s spokesperson Julian Espinoza says. “It reduces stress on the redwood forest ecosystem and improves visitors' arrival and parking experience.” Reservations are required year-round with two approaches: Visitors can either drive ($9 per standard vehicle or $30 for medium vehicles and $45 for large ones) or take the shuttle from Mill Valley ($3.50 per person 16 and older). Those fees are on top of the $15 park entrance fee for those 16 years and older. Booking starts 90 days before at 9 a.m. PT, with a few more being released three days in advance of visit days.
