This year was a strange one for travel, even domestically. Hopefully 2021 will return to a semblance of normalcy, and that means epic trips to national parks. As always, the National Park Service is offering a series of free-entrance days for 2021, when all 423 NPS sites will be free of charge.
Usually, about a third of the parks charge an entrance fee ranging from $5 to $35, but on these special days that fee will be waived.
