Location from Dragon Ball by Akira Toriyama
A million-kilometer serpentine path over the clouds of Other World — the road to King Kai's planet that tests the endurance and will of every dead warrior who attempts it.
Goku ran the entire length after dying to Raditz — it took him months and is considered an incredible feat. The path is monotonous, exhausting, and falling off means landing in a region of Other World that's difficult to escape. Princess Snake tempts travelers with food and comfort to trap them. The sheer length of Snake Way is the filter — only the most determined reach King Kai.
A narrow, winding path shaped like a massive golden snake, stretching endlessly across Other World's cloud layer. The snake's body forms the road, with a head at the start and a tail at the distant end. Below: nothing but clouds and an infinite drop into the realm of the ogres. No railings, no rest stops (except Princess Snake's palace, which is a trap).
Also known as: Snake Way, Serpent Road
