Thing to Do

Visit the Hot Water Cascade

Touch the Thermal Springs

The Hot Water Cascade is a place where you can touch the thermal water. Even though the water comes out of the ground at 143 degrees F, it is cool enough to touch by the time it reaches the pools.


Located at Arlington Lawn, this is the largest visible spring in the Park. Hot water emanates from the hill side near the Grand Promenade and flows under the path, down a steep cliff into two pools.
