The best time to visit Saudi Arabia is from November to March, when the weather is cooler and more pleasant for sightseeing and outdoor activities. Summers, especially June to August, can be extremely hot.
You can travel between major cities by domestic flights, modern highways for car journeys, or by train. The Haramain High-Speed Railway connects Mecca, Medina, Jeddah, and King Abdullah Economic City, making it convenient for travelers.
