Adder's Lair is the headquarters of the Death Adder, taking place in a demonic valley with lava and an active volcano. As with Dragon Canyon, parts of the track get destroyed during every lap of the race as the volcano rumbles, changing its layout.
The race begins with everyone in boat form on a river of lava. When they go ashore, snakes appearing in ancient ruins surrounding a statue of Death Adder. At the end of the track they return to the river of lava over a waterfall across the valley where it all starts.
The music for the boat and car portions of this track is a remix of "Wilderness" from Golden Axe. The music for the plane portions is a remix of "Turtle Village 1".
The player can see a giant skeleton with its hands opened outward. This is a reference to the character select screen from the original Golden Axe game.
