While most visitors stay clustered near the ferry pier and the hotel, the true magic of **Okunoshima** (Bunny Island) is found on its 4km coastal and hilltop trails. Walking the entire circumference of the island takes about 60 to 90 minutes at a leisurely pace. This journey takes you through diverse landscapes—from sandy beaches and turquoise waters to haunting WWII ruins and lush forests filled with hidden rabbit colonies.
For the active traveler, the “Full Island Loop” is the best way to escape the crowds and find a deeper connection with the island’s nature and history.
**Quick Take**: To see the best hidden viewpoints, I highly recommend the [Private Loop Trail & Heritage Discovery](VIATOR_LINK). A guide can lead you up the steeper hilltop paths to the **Artillery Batteries**, explaining the history of each site while ensuring you find the best spots for panoramic “Island-studded Sea” photos.

The Hilltop Challenge: The 360-Degree View
🎯 **Is the Climb Worth It?**
Yes. If you have the energy, take the path that leads up into the center of the island. Here you will find the ruins of the **Meiji-era Artillery Batteries** (built for the Russo-Japanese War). At the highest point, there is a viewing platform that offers one of the most stunning 360-degree views of the Seto Inland Sea. On a clear day, you can see all the way to the **Shimanami Kaido** bridges.

✅ Guided trek to the island’s highest viewpoints
⭐ Includes a curated “Hiker’s Kit” with water and high-energy rabbit treats
**Insider Tip**: The rabbits at the top of the hill see far fewer tourists than those at the pier. They are often very curious and will come running from the forest the moment they hear your footsteps. This “secluded swarm” is a much more intimate experience than the crowded pier area.

Frequently Asked Questions
Can I see the whole island in two hours?
Yes, if you walk at a steady pace. However, allowing 3-4 hours gives you time to stop, feed the rabbits, and explore the ruins properly.
Are there any dangerous animals?
Wild boars and crows live on the island. They generally avoid humans but don’t leave food unattended, as it will attract them.
