Park guide  /  When to book

Best time to book Yosemite National Park camping.

How far ahead campsites in Yosemite National Park fill up, and which months ease off. Computed from Ranger's own Recreation.gov availability tracking, so you plan the right lead time instead of guessing.

How full sites are when you book ahead

Peak season

Share of campsites already reserved in Yosemite National Park during peak season (June to September), grouped by how far ahead the booking was made. Higher means harder to get. Book earlier where the bar is already tall.

Computed from Ranger's own Recreation.gov availability polling (238367 site observations). We take the most recent status per site and date, so the numbers reflect real reservations, not held inventory. Data from Recreation.gov (CC-BY). See Attribution.
