I'm a foreigner living on a neighboring island. I always recommend for visitors to see this park and climb the tower to the viewpoint. The view of the surrounding islands is unmatched. It's, of course, particularly lovely when the cherry trees are blooming. But it's a fantastic view any time of year. It really puts the Seto Sea into perspective.
Not often visited but has very good view of the 3 bridges, Hakata-Oshima, Omishima and Tatara. Easy and pleasant walk to various observation decks.
It was well worth coming up here to climb the deck and get a full 180-degree view. No one there when I went. I imagine in summer busy, but I was there spring. I drove the circuit route. Very narrow going up and luckily only saw one car when I had stopped to take photos or one of us would have had to reverse.
There are toilet facilities in the parking area. Some nice natural stone structures and Buddha statues. The view is what you go for and the peace.
A bit of a climb but well worth it for the fabulous views!
Very steep, not recommended for cyclists. When we went up the observatory point was closed. Kirosan is better
