More than 8,000 gallons flow over the terrace every 24 hours at a constant temperature of 135 degrees Fahrenheit. The park has a free bath house where the water is maintained at 104 degrees for therapeudic bathing. Hot Springs has 6.2 miles of universally accessible trails and hiking trails. It is a full-service park with comfort stations, a Volksmarch trail, fishing, and a couple of boat docks. One of the reservable group picnic shelters is located here. Hot Springs is a day-use park. There is no fee for using the Bath House; however, there is a nominal charge for rental of towels and swimsuits.

Hot Springs State Park is pretty cool. It is certainly not as impressive if you are traveling from Yellowstone, but you can swim in the water from these hot springs whereas doing so could be deadly at Yellowstone. I totally recommend stopping by if you are in the area. The picture above is the view from across the river. You have to cross the suspension bridge to get this shot. There is an indoor and outdoor public bathing pool which is FREE. You are allowed to wade in for 20 minutes at a time. Be advised that the public hours are short. They closed at 5:30 the Friday we stopped by. This is not advertised clearly on the website. There are two commercial mini water parks on either side of the public pools that are open later, but cost more than free.

While you are in Thermopolis, you should definitely also make time to check out the Dinosaur Museum!

A really interesting area. You can enjoy a short walk around the hot springs before taking a soak in the indoor or outdoor bath house for free. There is a small water park next door to the bath house as well as some nearby hotels within walking distance. The wind river runs along next to the springs where we saw backside fisherman catching rainbow trout. We are glad we stopped by on our way to Yellowstone and wish we could stay longer.

If you're driving through this way, it's 100% worth a stop. Absolutely gorgeous park! I wouldn't go out of your way to come here though.

I absolutely fell in LOVE with Thermopolis. The bath house in the state park is free to soak from 8am to 5:30pm. Very clean and well kept facility. The park is beautiful. Please do yourself a favor and swing by if you are in the area. Nice people, nice soak, nice time. :)
