    Hiking

    Although it is known and named as a geyser, the Terminal Geyser is more like a steam vent than a true geyser. That does not make it less impressive. To get here, you have to follow a narrow, sometimes not that obvious trail. You can even climb down all the way to the steam that reveals a certain smell like rotten eggs. Always be careful around hydrothermal areas!
    Continuously steaming geyser near the South-eastern corner of the park, close to the PCT. While it may seem to harmlessly only vent some steam most of the time, it is in fact a geyser that can actually erupt with fatally boiling water or worse, so, like with all geothermal areas, practice caution on and particularly off the trail.

    Hiking

    "For your safety, stay on established trails and boardwalks. Ground in hydrothermal areas can look solid but may actually be a thin crust hiding pools of acidic boiling water or mud. Traveling off-trail in these areas may result in severe injury. Read more about exploring the park hydrothermal areas."
