Compass American Guides: Wyoming, 5th Edition
Geyser Hill Loop
Geyser Hill Loop Review
Along the 1.3-mi Geyser Hill Loop boardwalk you will see active thermal features such as violent Giantess Geyser. Erupting only a few times each year, Giantess spouts 100 to 250 feet in the air for five to eight minutes once or twice hourly for 12 to 43 hours. Nearby Doublet Pool's two adjacent springs have complex ledges and deep blue waters, which are highly photogenic. Starting as a gentle pool, Anemone Geyser overflows, bubbles, and finally erupts 10 feet or more, every three to eight minutes. The loop boardwalk brings you close to the action, making it especially appealing to children intrigued with the sights and sounds of the basin. To reach Geyser Hill, head counterclockwise around the Old Faithful boardwalk 0.3 mi from the visitor center, crossing the Firehole River and entering Upper Geyser Basin.
