Sounds like a fantastic experience. I never made it our to ojo but have a deep love for hot springs. I heard about harbin hot springs, but never visited.

Something deeply wholesome about mineral waters from the ground. The interaction of elements in a deeply nourishing manner. There's one near Redding thats on the River that is divine. Hot spring to cold river. yum yum.

You're making me wish we already had our sauna done. Welcome that heat to heal from within.
