Yosemite is one of the most famous U.S. national parks, so make sure to reserve your spot early! The ideal time to go is in spring or early summer when the falls are at their peak. It's a spectacular show of water, sound, and the sheer force of nature. There's also free bus service to take you to the different points of interest in the park. We spent three full days hiking and there were lots of different routes to choose from ranging from simple strolls to challenging trekking and even rock climbing. It's all very well put together and visitor-friendly, but there is still plenty of spaces where you can be alone and enjoy the silence and tranquility of nature.
