The Shimanami Kaido, also known as the Nishi Seto Expressway, is a remarkable 70-kilometer route that links Onomichi City in Hiroshima Prefecture with Imabari City in Ehime Prefecture. It traverses six islands across the picturesque Seto Inland Sea via a series of eleven uniquely designed bridges. This route is not merely a transportation artery but a celebrated destination, particularly for cyclists and pedestrians, offering unparalleled views of the sea and islands.
Visitors frequently highlight the stunning natural beauty and the exceptional cycling experience. Reviewers consistently praise the clear, azure waters and the panoramic sea views that blend seamlessly with the sky. Many describe it as a world-class cycling route, emphasizing the joy of island hopping and the sense of adventure. The well-maintained paths and the opportunity to experience the coastal environment up close are major draws. Some visitors note the tranquility and the feeling of being in a "big movie" due to the expansive, scenic landscapes.
For a fulfilling experience, visitors recommend dedicating ample time, ideally a full day or even two, to fully explore the route. While the entire 70 km can be cycled, less energetic travelers or those with limited time can incorporate boat rides or cycle shorter segments. Bringing knee pads is a practical tip mentioned by one reviewer, especially for the uphill sections leading to the bridges, which can be challenging. Staying at accommodations with sea views along the route is also highly recommended for an enhanced experience. The route is open year-round, 24/7, allowing flexibility in planning.
The Shimanami Kaido can be accessed from either Onomichi City (Hiroshima Prefecture) or Imabari City (Ehime Prefecture). Both cities are well-connected by public transport. From Onomichi, the starting point is easily reachable from Onomichi Station. Bicycle rental facilities are available at various points along the route, making it convenient for travelers without their own bikes. The route is clearly marked with dedicated paths for cyclists and pedestrians on each bridge, ensuring a safe and enjoyable journey.
A common challenge mentioned by cyclists is the uphill climb to access the bridges, which can be quite long, sometimes up to 2 kilometers for a single lane. While these sections offer rewarding views, they require a certain level of physical stamina. To mitigate this, consider renting an electric-assist bicycle, which can significantly ease the effort on inclines. Planning your route to include breaks and taking advantage of the numerous rest stops and viewpoints can also help manage fatigue.
