I used the free observation site for 1 night and 2 days during the Obon holiday.Even with a friend of mine who has been camping with me for a long time and his son, two cars, three solo tents, and two tarps, the cost was only 1,500 yen per person.The site is a flat area about the size of a soccer field, and the surface layer is mostly gravel, with no slopes and no large trees, so I don't think it's suitable for people looking for shade.On the other hand, there is nothing to obstruct the view of the mountain opposite, and the sky is open.I don't know if it was the Perseid meteor shower, but I could see a shooting star between the clouds near the zenith.There were temporary toilets, a water source, and a corner of what appeared to be a sauna at the edge of the site.There was also a fire hydrant.In addition to the temporary toilets, there are also toilets in front of the administration building, and the men's one has a urinal and a Western-style flush, and although there were a lot of moths, it was in good condition.There is a hose with a jet next to the washing button, so if you can't wash it off with water alone or it gets dirty, you can clean it yourself.As a side note, there seems to be a joke or a myth that people can mistake this for a washlet, but you should be careful as it could cause serious trouble.On the morning of the second day, I walked around the forest site, and the first thing that struck me was how well-maintained the forest was, with thinning and tree planting.There are paved roads within the park, but in many places you can easily take shortcuts by walking through the trees.There is also a stage, a play facility with a zip line, and a long slide, so your kids won't get bored.There is also a shower room and washer/dryer, so you can stay overnight without stress.The Rinkan site is naturally surrounded by trees, so I think it's suitable for people who like this kind of atmosphere.Personally, out of all of them, the free viewing site with excellent cost performance was the best.One thing to note is that this observation free site is difficult to get stuck in with pegs in quite a few places.If you use thin, lightweight, soft material, it will bend, so we strongly recommend pegs made of the hardest material possible.By the way, I bent the ends of two L-shaped pegs, and bent four thin pegs in the middle and at the head.September 15-16, 2024I went to the free viewing site for the second time following last month, and pitched a tent (1 solo, 1 duo, 1 dog) and a tarp in the same spot.This time the weather changed rapidly, with blue skies and rain falling, but although this site had a lot of gravel and was difficult to drive pegs into, I thought the water drainage was relatively good.After my previous experience, I changed all the pegs to titanium, and found that I could drive them with a larger, harder hammer.At this campsite, you can throw away almost anything as long as you properly separate it, and even OD cans and other things are equipped with degassing devices, so you can dispose of them by removing them.Another new thing I learned was that if I arrived much earlier than my reservation time, I could get in about an hour early if I paid 10% of the fare.
