Sand Dunes Swimming Pool
A Natural Artesian Hot Springs


The Pool and Spa

The Sand Dunes Swimming Pool is a family owned, natural artesian hot springs pool.

The pool is kept around 98-100 degrees Fahrenheit and the spa is around 105-107 degrees Fahrenheit.

Believe it or not but the water comes out of the ground at this temperature!


The Sand Dunes Swimming Pool is open year round despite the cold winter temperatures the San Luis Valley receives.

The pool area also offers sand volleyball courts and a basketball court for those that need a break from the water.

At the east end of the pool area there is a little stream with picnic tables and grills, perfect for a summer cookout.

Don’t forget your sunscreen because you will burn easily at the high elevation.

The pool also has amazing views of the Great Sand Dunes National Park as well as the Sangre de Cristo Mountain Range.


The Sand Dunes Swimming Pool is located in Hooper, Colorado approximately 20 miles north of Alamosa.

It is in a remote area of the San Luis Valley so online maps, such as Google Maps, have difficulty giving you exact directions.

The address is 1991 County Road 63, Hooper, Colorado 81136.

My Favorite Times and Tips

My favorite time of year to visit the Sand Dunes Swimming Pool is during the winter.

There is something surreal about swimming when the snow is falling and there is steam coming off the water.


The only disadvantage to going in the winter is the diving boards can be closed due to ice.

You also have to make a decision to get your hair wet and keep rewetting it or leave it dry because you hair will start to form ice sickles and your head gets cold!

And boy is it cold when you get out of the pool but the steam experience is worth the cold!

I also like to go at night any time of the year as there are so many stars to see.

Summer can be a fun time but I often find that I start to overheat with the hot summer air and hot water and spend more time sitting out of the pool than in it.

All in all, it doesn’t matter when you go as the water and views are wonderful.

However, I would suggest getting in the pool before trying the spa.

If you get in the spa first and then go to the pool it will seem cold even though it’s 100 degrees Fahrenheit.


The water enters the pool at the southwest corner.

This is where you will find the hottest water and then it begins to cool as it travels to the deep end.

On the wall next to the baby pool you will find a bench that allows you to sit near the incoming water and enjoy the heat.

Mainly in the summer there is a water fountain running which allows the water to cool before entering the pool using the outside air temperature.

It is fun to sit under it and allow it to massage your back.

Have a nice swim!
