This is such a unique landscape! Looks like ice and snow although it is really just mineral formations. It was raining when we went and cold but we could feel the heat coming out of the springs much better.

The springs were not flowing much at the time we were there and we were told that this was due to some previous systemic activity. None the less it was still worth seeing as the springs and the minerals in the water have created some very interesting areas where the water flowed.

An amazing attraction which is a must do in your yellowstone list. Try parking your vehicle on top the hill which is also where the highlight view of the mammoth would be + less hiking up!

If you fell asleep in the car ride here you might think you'd been driven to Venus (minus the blue sky and breathable air). The hillsides glisten white and yellow in the sunlight as steaming water spits and streams down the sides. Calcified cascading tiers form small pools in the path of a warm waterfall. Its as if Mother Nature... More

I read several reviews and one did say that if you do not have time to skip it. We spent one day on what I call the southern ring and loved everything we saw. We did skip a few things to try to make it completely around the southern ring in one day. We ended up getting to go back... More

Mammoth hot springs was one of the prettiest attractions at YNP. When I showed people photos, they thought they were paintings. There are different colors throughout. The white on top of the orange/brown is just beautiful. The walk around it is easy as well. I think this is a don't-miss attraction in the park.

This site is amazing as it is just made by nature. It's cascading and bubbling attraction brings out the beauty of Gods amazing beauty. Take time and it's not far to it from your car. I was in awe of how these formations are imperfectly perfect. Take plenty of pictures and discuss this with your family as you take it... More

This was a nice stop to take in where the cold water of the river meetings scalding hot water coming up from the ground to form a comfortable blend where people can sit in different pools. The hike from the parking area is approximately 10 minutes and an easy walk and there is plenty of scenery to take in...additionally a... More

This was a very beautiful and interesting land formation. It is different than most of the other sites on Yellowstone; little pools cascading down the hills like steps. I really enjoyed this site but it is a bit of a trek and far away from most of the other sites in Yellowstone. It is one of the northern most points... More
