Whirlpool (Baxtorian Falls)

The Whirlpool is also an object at the end of a long pier in the lake above Baxtorian Falls. Right-clicking on it gives the option to "dive in". Jumping into it transports a player past the falls and to the shore on the east side of the lake at the bottom of the falls (just above the tourist center), but the player will take about 6 points of damage in the process. After doing the Pyre ship part of Barbarian Training, the player will instead be transported to the Ancient Cavern.
