3. Seasonality and trails in parks. Most national parks in America are open year-round, but seasonality is still particularly relevant for some. For example, in Sequoia National Park, free shuttles—buses that can take you anywhere in the park—do not run between September 8 and May 22. Some routes are even closed to visitors. Therefore, before visiting a park, check the park's schedule and activities on the National Park Service website.
4. Parking. During the peak season (May-September), it is quite difficult to find a parking space close to the main attractions of the park, so it is advisable to arrive early in the morning. Most parking lots are located near tourist centers (Visitor Centers) and major attractions. In America, it is not worth breaking the rules and parking your car in a disabled parking space — not only will you be fined between $200 and $1,000 (depending on state laws), but you will also be met with disapproving looks.
Bonus Tip: I recommend purchasing a Passport to Your National Parks (it costs $10). It is a small book with a list of all the national parks in America, where you can mark your visit to the park as a souvenir (stamp, date, or sticker). Stamps are completely free, but stickers can be purchased for $2 and up.
Now let's take a virtual tour of the most famous parks in Utah, Arizona, Nevada, and California and figure out what to see, where, and when.
I am sharing my personal experience, observations, and the results of tons of reading about America's national parks :)
Yosemite National Park, California
Yosemite is rightly considered one of the most beautiful parks in the United States. It's no coincidence that its views inspired Apple to create the Yosemite operating system — you can see the famous El Capitan mountain on the Macbook screensaver. You should set aside at least a few days for the park, and even better, stay there at a campsite. You can book a camping spot here. The park is so huge that one day will definitely not be enough. It covers an area of approximately 3,000 square kilometers.
