description Beauty Pool Overview

Beauty Pool is a thermal hot spring located in the Upper Geyser Basin of Yellowstone National Park, specifically within the Biscuit Basin area. The pool is characterized by its deep blue water and richly colored bacterial mats that surround its edges. It shares a subterranean hydrothermal connection with nearby Chromatic Pool, causing observable shifts in water levels between the two features over periods of weeks or years. It is maintained by the National Park Service for public observation.

help Beauty Pool FAQ

Why does Beauty Pool change color?

Its colors come from the interaction of hot water, minerals, and heat-tolerant microbial communities. Changes in temperature or water level can shift where different microorganisms thrive, altering the visible bands around the pool.

How is Beauty Pool connected to Chromatic Pool?

Beauty Pool and nearby Chromatic Pool are hydraulically linked underground. Over periods ranging from weeks to years, one pool's water level and activity can rise as the other's declines.

Where is Beauty Pool in Yellowstone?

Beauty Pool lies in Yellowstone's Upper Geyser Basin, the same broad thermal area as Old Faithful. Visitors must remain on designated boardwalks because the surrounding crust can conceal dangerously hot water.

Can visitors swim in Beauty Pool?

No, swimming or soaking in Yellowstone's thermal features is prohibited and can be fatal. Beauty Pool is a hot spring with unstable ground and scalding water, not a recreational pool.
