Glenwood Hot Springs Pool, Lodge & Spa - Hot Springs in Colorado


The largest natural hot spring pool in the world is said to be located in Colorado.

It is a major tourist attraction that attracts skiers in the winter and families in the summer who come for the water slides.

Hotel Colorado

Glenwood Springs is a 2.5-hour drive from the state capital, Denver.

It is also an easy walk from the train station, a rarity in the car-dominated U.S.

The small town is known as the Most Fun Town in America.

Hotel Colorado

The Hotel Colorado, once known as the Little White House, was still in operation, as Theodore Roosevelt, the 26th President of the United States, was a favorite guest.

Rumor has it that Teddy Bear was born when the president's daughter named the stuffed bear Teddy after the hotel gave it to him, who was disappointed by his lack of hunting success.

Glenwood Hot Springs Lodge

Unfortunately, the magnificent Hotel Colorado does not draw the thermal water.

Meanwhile, its neighbor to the east, the Glenwood Hot Springs Lodge, has a hot springs pool that is said to be the largest in the world.

Guests have free access to the pool during its hours of operation (9am -10pm).

The hotel facilities were old-fashioned.


The hot spring pool appeared to be targeted at day-trippers.

Many tourists entered without interruption as soon as it opened, and the facility was huge enough to accommodate them as well.


The pool is divided into two parts: the large pool in the foreground is 405 feet long x 100 feet wide.

The smaller Therapy Pool in the background is 100 feet long x 40 feet wide.

With its total dimension, it is said to be the world's largest hot springs in the form of pools.

Large Pool1

A public bathhouse building that opened in 1888 (now used as an esthetic building) remained by the pool.

The area, once inhabited by the Native American Ute tribe, was occupied by white settlers in the late 1800s with the Gold Rush.

Since that time, the area has had a long history as a hot springs resort.

Water Slide

The large pool with water slides had lukewarm water of about 92 degree F.

It was heavily watered and did not feel like a mineral spring.

Therapy Pool

The Therapy Pool was at an appropriate temperature of around 104 degrees F.

The large amount of salt in the water should be noted to cause dizziness.

However, there was a smell of chlorine disinfection, so I could not enjoy the goodness of the water.

Source of the Spring

The source of the springs shining behind the facility was so much more attractive.

I'd love to dive into this pond.
Be sure to be careful.

A drinking fountain (?) set up beside the pool; the water there does not seem to be disinfected.

The Original Glenwood Springs Cocktail

Even though the use of water was not so good, the huge pool with its slightly cloudy water against the backdrop of the Rocky Mountains was a sight to behold.
