NATIONAL PARKS MIDWAY GEYSER BASIN @Kim Seng YELLOWSTONE IN A DAY While you can’t see all of Yellowstone in a single day, it’s relatively easy to prioritize the fascinating geothermal features for which the park is best known. Starting in the early morning at the east entrance, head to the West Thumb Geyser Basin , on the edge of Yellowstone Lake. Two short boardwalk loops will take you past the steaming Thumb Paint Pots , vibrant Abyss Pool and minuscule Fishing Cone . Then head over to Old Faithful for the next eruption, followed by a casual lunch at Geyser Grill . Your next stop is Midway Geyser Basin , also known as Hell’s Half Acre for the vaporous clouds clinging to its banks. The main attraction here is Grand Prismatic Spring — the third-largest hot spring in the world. This pool is bigger than a football field. Its enchanting colors are caused by the different species of heat-loving bacteria that live in the spring.

GREAT FOUNTAIN GEYSER @johnmyers411 Next, you’re off to the Grand Loop just south of Madison. Take Firehole Lake Drive , a 3-mile scenic trip past at least a dozen geothermal features. With luck, you’ll catch one of Great Fountain Geyser ’s breathtaking and highly unpredictable displays. If you’re feeling adventurous (and time’s on your side), keep going for Artist Point ’s bucket-list overlook of the Grand Canyon of the Yellowstone ’s tumbling Lower Falls , then over to Brink of the Upper Falls overlook for more cascading grandeur. Now, head for serene mountain views surrounding Yellowstone Lake and back out the east entrance. Feeling hungry? Pause for a casual dinner at the historical Lake Yellowstone Hotel dining room.
