Leet Peak, also known as Mt. Super Mario Wiki, is a mysterious peak and the tallest one in existence. According to Plumber, the peak's height is "a hundred trillion miles tall". The peak is enchanted, so it does not appear as large. No user has ever gone to the bottommost location: 1337 Cave. In 1337 Cave, 1337Yoshi HQ can be found inside of it. 1337 Cave is on the opposite side of Leet Town.
The height of Leet Peak is unknown, but the base of the peak is covered in clouds, meaning it is larger than one may expect.
