Mount St. Double Dare (also known as Mt. Saint Double Dare) is an obstacle in Double Dare.
In the 2018 revival, it is always the 8th and last obstacle on the course. It consists of a mountain looking like a volcano with green slime "lava" flowing down it. When contestants reach this obstacle, they have to climb up it, grab the flag, then climb back down in order to finish off the obstacle course and win the grand prize.
For the 2018 revival's Halloween special, Double Scare, it was renamed 'Mount St. Double Scare'.
