This is one of the best things one can see and is best in the world. It is alarge complex of hot springs adjacent to Fort Yellowstone. Take the board walk and enjoy the different and ever changing terraces in the Mammoth Hot springs. This beautiful view of the hot springs can be viewed at different locations along the long... More

Mammoth was absolutely spectacular before the big earthquake in the late 50s. This caused a lot of the Hot Springs to become dormant. You can still see some of the active Terrances and even the ones that have run dry are pretty spectacular. Personally when I come up here I like to drive the small one way loop road that... More

Such a cool geothermal feature in Yellowstone. Be prepared that the boardwalk/steps can get slightly steep, but there are benches that allow one to take a minute to rest, if need be. This is another crowded spot in Yellowstone. Parking can be a bit of a headache as well, but we found a spot nonetheless.

I love Mammoth, since I was a kid this place has held for me a magical quality that has me expecting faeries or gremlins at suddenly pop up from Behring one of the terraced falls. Easy boardwalks mean you're rarely alone with your thoughts, but quiet corners can be found.

This area is one of the fastest changing in Yellowstone. Very active hot springs and geisers in the area! Watch your children. Also their are anilmals everywhere! drive slow and keep an eye out. We saw bison, elk, coyote, and pronghown within a few miles of each other!

We visited Mammoth Hot Springs on our way to Lamar Valley and it was worth it as the "steps" are really spectacular to see and offer some very nice photo opportunities - one of the musts in Yellowstone. There is a lot of parking there, even for an RV. Some roadworks were happening when we visited in July so there... More

Hot springs and terraces, which were good to see, but it was meltingly hot when we were walking round, and there are quite a lot of stairs. Also quite a few of the terraces had dried up, which happens from time to time depending on the geothermal conditions.

A wide variet of colours through the micro organisms. Wonder what it would have been like thousands of years ago. The terraces look stark until you catch the reflection of the water shimmering off them. Great exercise into the bargin. Another of Yellowstone's wide range of wonders.

I'm a succer for hot springs and the formations from the sediments is just awesome. It's definitely one of the main attractions in Yellowstone so allow yourself plenty of time. Be ready to fight some crowds. We saw deer here. Plenty of great photo opportunities. Do take the time to do the loop.

This was the first place we stopped at on our way through the park from the North Entrance. We walked around both the lower terraces and along Upper Terrace Drive, took about 3 hours. Well worth the walk if you can, but there are lots of stairs and climb pretty high pretty fast, so not one for a stroller. We... More
