 This is the best of all secret onsens that I visited so far.

 I recommend you should go there by small car and you should accept the damages to your car lol

 First, designate Beppu Onsen Relaxation Land in the car navigation

Passing through this Relaxation Land and Beppu Myoban bridge, you will see this signboard ob your left

Then turn left here

You will find two-way roads below, and go up to the left here.

Finally you will find the signboard of the guide for Hebin Onsen and Nabe Onsen.
 
 ……What?

The Words of `Nabe Onsen` have been deleted from the signboard…..
 
Anyway….. Lets go to Hebin Onsen!

Then you will pass the gate

 Two-way road again

Nabe Yama Onsen to the right, so we went to the left

From here, very steep mountain road continues like forever

My car was getting dirty as we pass the roads like puddles

 Going forward with patience and screaming, passing scary and narrow road, I was about to fall down from the road

That`s it! Here is guide!

Parked my car in the space in the left
 
Walked through this narrow road alongside this guide

Going down this rock stairs
 
Oh, Yoko found something

Looks surprised!

 Here we are!

Can`t believe we found Onsen in this mountain!

 Three beautiful onsens alongside the floating river
 
 Incredible view!!!!

 What a surprise there is Onsen in this place!!!
 
Also, this is like bath, and we can dip into this deeply

There is dressing room like this place

Get into Onsen

 Not too hot, nice temperature, and beautiful!

Onsen for beautiful skin with 100% natural water, although a bit slimy

 When we got into Onsen with swim jacket, local old guy scolded at us, saying `that’s rude!` `take off your swim jacket!!!`
So girls should be here when no one is in onsen…

Secret Onsen with wonderful view and night view with stars
I think everyone should visit this Onsen once in your lifetime

No taste on the water

However, please keep in your mind that the way to this onsen is reallyyy hard! So please watch your way!

Next, Nabe-yama Onsen
