    Multnomah Falls parking permit

    Required in summer; set a reminder

    A timed-use permit is needed for the I-84 parking lot from 9 a.m. to 6 p.m. in summer (May 22 to September 7 in 2026). Arriving before 9 or by shuttle avoids it. We set a reminder two weeks out.

    Smokies parking tag

    No window; buy before you go

    No entrance fee, but any car parked more than 15 minutes needs a tag: $5 a day, $15 a week or $40 a year. Federal passes don't cover it. We set a reminder a week out.

    Good news

    No timed entry in 2026

    Arches, Glacier, Mount Rainier and Yosemite

    All four dropped their vehicle reservation systems for 2026. Glacier still limits Logan Pass parking and runs a ticketed shuttle, so it's listed above. Watch for 2027 announcements.

    Rather not set nine alarms?

    When Alyssa plans your trip, the booking timeline comes with it: which windows matter for your route, what to grab first and a backup if the first choice sells out.
