If you are a visitor that just wants to see the sights with minimal hiking and exploring, a 3-to-4-day trip to the park will give you plenty of time to see the main attractions. If you consider yourself an adventurist, it would be a better idea to plan a 5- to 7-day visit. Yosemite National Park is a massive park with so many attractions and the more time you can spend at the park, the better the experience you will have.
