What it does
This bill amends federal law to require that entrance fees be waived on six specific days each year at national parks and federal recreational lands—MLK Day, the first day of National Park Week, Juneteenth, Great American Outdoors Day, National Public Lands Day, and Veterans Day. Currently, the Secretary of Interior has discretion to offer fee-free days; this bill makes six days mandatory while preserving the Secretary's authority to add more.
Why we flagged it
The bill's operative mechanism is a straightforward mandate to provide free admission on six named days, converting discretionary authority into a binding requirement. It is a public-benefit measure with no hidden riders or narrow carve-outs.
What the text implies
- The bill ties fee waivers to specific dates (MLK Day, Juneteenth, Veterans Day, etc.), effectively using park access as a vehicle for national commemoration and civic messaging around those holidays.
- By mandating six fee-free days, the bill reduces discretionary revenue for park operations and maintenance; the fiscal impact depends on appropriations and whether Congress backfills lost entrance-fee revenue.
