Itsukushima Shrine, famous for its 'floating' torii gate, is a must-see in Miyajima. Accessibility can be challenging due to tides and some areas having steps, so check tide schedules beforehand. While solo visits are common and rewarding, guided tours offer deeper insights into the shrine's history and significance. Be aware that high tide offers the iconic floating view, while low tide allows walking to the gate. The cost to enter the shrine is approximately ¥300, and a typical visit lasts 1-2 hours, allowing time to explore the shrine complex and surrounding island. Note that the torii gate is currently under renovation, which may affect the viewing experience.
