Upper Geyser Basin & Morning Glory Pool
Upper Geyser Basin
The world's densest concentration of geysers. A roughly 2.5 km boardwalk links Castle, Giantess, Daisy and other geysers to the finale, the colorful Morning Glory Pool.
The basin holds about a quarter of Yellowstone's geysers. After watching Old Faithful, follow the boardwalk north past Castle Geyser, Beauty Pool, Grandmother Geyser and Riverside Geyser to Morning Glory Pool. The round trip is about 4–5 km and takes 2–3 hours. The visitor center posts predicted eruption times for several of the reliable geysers, so you can plan your route around them. Coins tossed in by visitors once cooled Morning Glory Pool, and its blue center has since turned yellow-green. Always stay on the boardwalk and never touch the water.
