NO VEHICLE DAY-USE RESERVATIONS REQUIRED FOR 2026!
Day-use visitors to Yosemite National Park will not be required to make a reservation to enter the park in 2026. This provides added flexibility for travelers, while the park remains committed to managing traffic, protecting natural and cultural resources, and supporting safe, enjoyable visits for all.
Visitors traveling in 2026 are encouraged to plan ahead for a smooth Yosemite experience:
- Start your Yosemite adventure the easy way — purchase your digital entrance pass ahead of time.
- Travel midweek when possible--there are lighter crowds and easier parking.
- Start your day early, especially on weekends and holidays.
- Think beyond Yosemite Valley. The park has more incredible landscapes well beyond the most photographed spots. Check them out...download Beyond Yosemite Valley.
- Visit the park with a local guiding service or on public transportation like YARTS (Yosemite Area Regional Transportation System)
- Sign up for real-time park updates by texting “Yosemite” to 33311 to receive timely parking and traffic alerts as conditions change throughout the day.
- Check the park website for real-time conditions, seasonal updates and trip-planning tools.
