This place is a peaceful spot that I found quite enjoyable. I visited in late November to take a nap after arriving on an early ferry. It seems like it would be suitable for an overnight stay during the off-season. However, I didn't notice any clear signs indicating that overnight stays are not allowed.
This location is suitable for overnight stays as it is quiet and free of noise. You are likely to find ample space in the car park, especially after 8pm when it is usually empty. The road nearby is not heavily trafficked, ensuring a peaceful experience.
