The early window
Arriving before the morning surge, often before 8 a.m., is the most reliable way to find parking at popular corridors and to hike before trails get busy. It also tends to mean better light and cooler temperatures.
The midday crunch
Late morning through mid-afternoon is when entrance lines and parking lots peak. If you must arrive then, expect to wait and have a backup plan for full lots.
Shuttles and timed entry
Where shuttles or timed-entry windows apply, the first departures and earliest slots are the most valuable. Confirm current rules and release times on the official site.
