best onsen in hakone

our trip has two days planned to stay in Fuji region. About Hakone, we want tips about onsen, specially in Yumoto.

We aren't seeking for luxous places. But best in water quality, pleasant place, really calm, silent, and in deep touch with nature...

So please, give us this help? What are the best onsens there?

THANK YOU!

How about staying in Atami?

It seems really great Joshua. but we chose Hakone because is very close to Narita, and this will be our last travel's part.

We have the conscience "all onsens" in Hakone are quite comercials and crowded, but, if we could found the "less" crowded it would be really good. :)

Thank you anyway!

Hakone is not very close to Narita, by the way. I wonder if you meant that within Hakone, HakoneYumoto is the closest.

I stayed at Hoeiso onsen inn in Hakone. This hotel is ryokan(Traditional) Japanense onsen. It not luxury but a very traditional, quiet, very nice, friendly staffs, spacious room, 2 outdoor onsen(public/private), 2 indoor onsen(public), breakfast(Japanese or Western) and dinner(Japanese) included deliver to your room. They are quite expensive but it worth it! I would come back!
