Blue Star Spring is located in Upper Geyser Basin, the same geyser basin that is home to the much-loved Old Faithful Geyser. Upper Geyser Basin has the highest concentration of geothermal features within Yellowstone National Park. You can wander the basin on a series of boardwalks (be careful on chilly mornings, they can be slippery) and see many of the features up close. Other geysers in the area include Grand Geyser, Castle Geyser, Daisy Geyser, and Riverside Geyser.
