I have been to this location a few times over a 50 year period, and can recommend it at anytime of the year, but I think it was most impressive in the winter. There is more water flowing, and the steam makes it look more impressive. The last time I was there in the summer, it was almost dry and... More

The sights, the trails, even the sulphur smells are so cool to experience! Also in late September there were LOTS of elk around bugalling!

Mammoth Hot Springs are amazing, and when we hiked the access trails there were about 10 other people there with us. Cool geology, beautiful colors and shapes as the mineral rich waters flow over the calcium carbonate deposits, and yet we had some privacy. Go now!

By all accounts this area should be ugly, it's barren, mineral covered and hot, but somehow when you see it all you can see is it's beauty. You can do a drive through, which I suggest, and park and walk. If you have time do both. Some of these features need to be seen from different vantage points to really... More

This is an area in the northern area of the park that is spread out over a large area. Walking is an issue for one of the members of our group so we went to the parking lot next to the hotel and did a look from there. You can get closer but it wasn't going to work for us.... More

Stunning. Unbelievable. Other-worldly. Wow. These and many other words of awe will escape your lips as you walk around this extraordinary natural site. There's no question that the intersection of underground heat and steam with the chemicals of the area have caused a unique thermal area that has formed structures on the surface of the earth that you may never...

Lots of boardwalks and stairs to walk and see many great views. Lots of geysers, mud pots, springs and unusual formations to see! The parking along the road was packed, but we eventually found a spot. Plan over an hour for the main area and be sure to bring a camera! We saw lots of elk just hanging out as... More

This looks like space! Geysers, hot mud pots & some water springs flowing here. Very unusual! This is one if the best spots in Yellowstone. Plus the Elk invade the green spaces near he buildings so you have hat to look at too! Just loved it!
