Yes, Kintai Bridge serves as the main access point to Iwakuni Castle. After crossing the bridge and walking through Kikko Park, visitors take a ropeway up Mount Shiroyama to reach the castle at the summit. The combination ticket for 970 yen covers the bridge crossing, ropeway ride, and castle admission, making it convenient to visit all three attractions in one trip. The castle offers excellent views of Kintai Bridge from above.
