Lower Geyser Basin

"Estimated Time: 1 to 2 hours The Upper Geyser Basin is the larger area home to Old Faithful, but there’s so much more to see here! This area has the most significant density of geysers and other geothermal features globally! Heart Spring Hot Spring, a sapphire blue pool shaped like a heart Sawmill Geyser, a unique feature that vigorous splashes water several feet in the air Beauty Pool and Chromatic Pool, two interconnected, deep chromatic springs (only a hint of what’s to come at Grand Prismatic Spring) Grand Geyser, the tallest predictable geyser in the world (it only erupts every ~6 hours, so only stick around if you’re in the area near the predicted eruption time) Riverside Geyser, a giant, predictable geyser that spews into the Firehole River (like Grand, it only erupts every ~6 hours, so only stick around if you’re near the predicted eruption time) Morning Glory Pool, a stunning, multi-color pool at the furthest distance from the visitor center (easily the best feature in Upper Geyser Basin!) Daisy Geyser, a predictable geyser that erupts every 2-3 hours with great views of the rest of the Upper Geyser Basin Castle Geyser, a unique cone-shaped geyser that erupts roughly every 14 hours https://www.wellplannedjourney.com/best-things-to-do-in-yellowstone/"
