The world's largest natural warm water indoor swimming pool. *NOT A HOT WATER SPRING* The town is named Hot Springs, but Evans Plunge Mineral Springs itself has never claimed to be any hotter than it is, which is consistently 87 degrees year-round, the Lakota called it "Minnekahta" meaning "warm water." 5,000 gallons of water flow from the mineral springs every hour, completely refreshing the water in the pool numerous times every day. Evans Plunge Mineral Springs opened in 1890 and is the oldest attraction in the Black Hills. Currently owned & operated by the City of Hot Springs, Evans Plunge is proud to be open year round and offers both an indoor and an outdoor pool, plus a health club, which is included with admission!

So much fun for the whole family

The water is 87 degrees year round, but even inside it started to feel a little chilly. We went during a weekday in October and just about had the whole pool to ourselves. The... read more

Our 15 yr old swimmer granddaughter wanted to swim laps one morning of our trip and her 11 yr old sister played on the indoor slides. Both loved the facility. Extremely friendly, helpful staff, clean dressing rooms. It's a huge pool, divided into different areas for exercise, free swim, play. Their mom and I strolled the walk along the river,... More

Not quite what we expected, but fun to be a part of history. We bounce around in the pool for @ 1/2 hour. Being October when we visited the pool was not very busy.

I have included a photo of how it was in the 70s. Pros: 1. warm water is good for all ages, muscles and arthritis, as are the minerals in the water; it's like a big bathtub full of epsom salts. 2. Rock pabble bottom. 3. Real hot springs, not a heated pool 4. Water turnover is constant 5. Slides, and... More

We had a long day of driving, so we decided to give the kids a break and stopped at Evans Plunge. This is a historic place... so don't expect a fancy modern water park. But, it was the perfect stop for us. There are three big slides, an area for toddlers, and a decent size area to swim. We only... More

We decided to take a dip and enjoy the fresh spring water.... Evans plunge was expensive to go into and I must say I felt a tad ripped off when we simply went for a swim and the kids had a few goes on the slide. The bottom of the pool is gravel as its a spring so it was... More

I've lived a lot of places, but it's worth a trip just to go swimming in Evans Plunge. It is the most delightful water, so clean, so pure, no chlorine because it's built on natural hot springs. And, I love the feel of warm water on my joins and muscles! What is really special, on a icy cold winter day,... More

It's been 30yrs since I've been here and the place hasn't changed, literally. It's a great concept they have going here but once people figure out how nasty this place is they won't be coming back. Considering what it costs to get a family of 6 in the pool, I'd think they'd have extra capital to update something, anything..........

This was a great stop for the kids. We loved the river pebble bottom and the sulfur water felt amazing! The water slides were fun for all of us and our son had a blast on the rings. It was a little pricey, but worth it!

Water was colder than expected since it's advertised as a hot springs, but a minor detail. The place is dated and could certainly use a major freshen up, but don't let that deter you from going. The place is huge with plenty of room to not feel crowded. The outside waterslides are a bigger hit with my 6 year old... More
