Warp Zone. This level contains a Warp Zone with pipes to Worlds 2-1, 3-1 and 4-1. It is the fastest legal way to skip ahead in the game.

Pipes you can enter. One of the pipes can be entered by pressing down on top of it. The other 4 are decoration or obstacles.

Every number above is read straight out of the game files this site runs on, so the map you play here is the map being described.
