Tired of the concrete environment of Tokyo? Wish you could go see some green?
I recommend going to a cave if you feel like you just can’t beat the heat. Luckily Okutama has some pretty good ones.
If caves aren’t what you are looking for you can scroll down for some descriptions of different walking trails you can take.

Take the bus board for the limestone caves…But it is probably wiser to attempt to come by car because it is really in the middle of nowhere.
I went to Nippara Caves and I highly recommend them.

The town where the parking lot is to leave your car. It was about a 15 minute walk to the caves.

Inside the caves. As you can imagine, they were very cool and comfortable. Japan gets uncomfortably hot and humid.

All of those silver glittery circles are coins. They are offerings for this little shrine that was inside the caves.

The area around Nippara. Okutama is pretty much all mountains, river, and wildlife like this.
Walking Trails
All of them can be viewed here: http://www.okutama.gr.jp/
Unfortunately, they are all in Japanese! Be aware that the trails can have unexpected closures due to weather conditions and damage to trails. There is a visitor center right near Okutama Station where you can check the trail conditions.
