Mammoth Hot Springs in Yellowstone National Park is a gigantic travertine terraced hot spring near the north entrance of the park. The whole nature of this hot spring changes from week to week with different parts of the spring being more active at different times – so every time you go there it will look a little different from the last time you saw it!
They’ve built a large boardwalk system so you can walk around to the different areas of this site, (you’ll find a lot of boardwalk in Yellowstone because the ground is too unstable to walk on). We were completely amazed by how varied the landscape looked – one minute you’re looking at a beautiful water filled stone formation, the next minute the terrain has changed and it looks as though you’ve landed on Mars!
There’s also a bit of a village in the Mammoth area with a store, restaurants, and camping area. We didn’t stay in this region because we read a tip that it’s the least desirable place to camp in the entire park because it’s quite hot and smells strongly of sulfur – the tip proved to be spot on, so we were super thankful we choose not to camp here!
This photo in particular really makes you feel like it may well be another planet!
As we were exploring the upper part of the hot springs, a wicked thunderstorm rolled in and chased us out – maybe next year we’ll get to do a bit more exploring in this area!
As a final tip, we also heard this area is very crowded during the mid-morning to late-afternoon hours, so we went just before sunset which worked out well with the glowy golden light cast across all the formations! Mammoth Hot Springs was definitely a highlight of our Yellowstone trip – after a full day of geyser sight seeing this one still stands out in my mind as one of the more fantastic sights!
