The cave with warm water is worth seeing.
As the place is a little too well known, crowds are inevitable on holidays.

I could not help but stop the car to admire the vast plains that suddenly spread out on the side of the road.

It was the Valles Caldera, created by a significant eruption 1.25 million years ago.
Not only does it retain a distinct lava dome in the center, but it also shows numerous geothermal activities and has been designated a national protected area.
Natural steam bath

Spence Hot Springs is located where the highway takes a sharp curve over the mountains on the caldera's western rim.
Nice parking is available and free for day use.

Get out of the car here and hike 0.7 miles round trip to the hot springs.
It is essentially a less difficult course.

A fine stairway was provided on the mountain road to the San Antonio River.

Good maintenance condition, indicating its popularity.

After crossing the stream by a steel bridge, the next step was uphill.

In the end, the warm spring water flowed down from the top of the hill and was muddy.

It was thought to be a difficult point, such as after rainfall.

When the trees break off and a huge volcanic rock appears in front of you, you have arrived at your destination!

The pools were located around the rock, and the slope further up was gently leveled.



There were two soaking pools in the form of steps, each of which was capped by large rocks.

The warm water was only in the upper pool, so the lower pool was quite lukewarm, with a water temp of 81 degrees F.

Inside the cave, which was small enough to fit two adults, the space was miraculously hot and humid.
Clear, odorless, tasteless water gushed quietly from the walls.

Even the 100 degrees F water felt warm enough because the entire cave was warming up like a steam bath.
Hopefully, I would have had this space all to myself, but through the rocks, I could see the next guests waiting their turn.
