Gigantic Warm Spring

Gigantic Warm Spring

Gigantic Warm Spring is a little piece of Montana heaven, conveniently nestled in between the North and South Moccasin Mountains of Fergus County on the Vanek's Paradise Ranch. The venue is a short drive approximately 14 miles north of Lewistown, MT on Highway 81. It is an ideal spot to cool down on a hot summer day with a constant water temperature of 68 degrees Fahrenheit year round. Gigantic Warm Spring is considered the world's largest warm spring and third largest natural spring, flowing an average of 50,000 gallons per minute. The venue offers scenic views of Central Montana's countryside and an opportunity for the public to enjoy a picnic and a swim at one of Montana's unique natural wonders. 

Opening Day is weather-dependent and approximately June 1st. Closing is Monday, Labor Day Weekend. Our Seasonal Hours are 12 PM to 9 PM daily.
