The whole area is designated as part of the Setonaikai National Park.
From the observatory, you can see the beautiful Seto Inland Sea. Both “Kabutoiwa Observatory” and “Hoshifuru Observatory” are within walking distance from the parking lot.

There is also an auto campsite and accommodation facilities.
The campsite looks a little old, but the auto campsite has a good atmosphere.

There is a mountain climbing route from the parking lot dedicated to Noro mountain climbers, and there are many rocky seas and strangely shaped rocks, so you can enjoy climbing. It takes about 4-6 hours round trip.

For first-timers, there are various spots around the "Noroyama Visitor Center", so I think it would be good to collect information there.
