Yosemite National Park anticipates a very busy Fourth of July weekend and visitors are urged to arrive at the park very early to avoid potential traffic congestion and difficulties with parking. Fireworks are strictly prohibited in the park. Additionally, with the ongoing drought, conditions are extremely dry and visitors are asked to avoid campfires unless absolutely necessary. https://www.nps.gov/yose/learn/news/yosemite-national-park-expects-busy-4th-of-july-weekend.htm
