Hello fellow national park enthusiasts! I posted this last week but have added a few clarifications.
I’d like to bring to your attention a big change to the confusing entry requirements for Glacier National Park and Yosemite National Park starting this year.
National parks usually require some type of entrance fee unless you have an annual pass or a senior pass (i.e., America the Beautiful pass; there are a few other types of passes with which you might be familiar). This is still required at Glacier and Yosemite.
Starting this year—May 6 for Glacier and May 21 for Yosemite—through September 2021, both parks are requiring an additional entry reservation ticket.
LET ME REPEAT. To get into Glacier and Yosemite National Parks this summer (and most likely all future summers), you will need a park pass (or pay an entrance fee when you arrive) AND a reservation (with an entry reservation ticket in hand or on phone).
