Balloon Park is an amusement park-themed Zone with bright colors and a circus-themed structure. The Zone's pathway uses flags and illustrations of circus animals as part of its decorations. The background of this Zone is a night scene of a city with bright lights and far-away clouds.
Begin the Zone by going right through a loop on the right to two moving elephant platforms. Quickly drop into the moving gap between them, though this is a tricky maneuver. Below are three Bumpers above a neon yellow floor.
From here, the player has to progress right and upwards using yellow balloons. Bounce up to the left, then try to land right on top of another balloon, and bounce up to the start pole again. This Zone can be much easier to progress through using Tails, who can use his ability to fly.
There is a known cheat in this Zone, making it possible to finish the level in under 10 seconds. Right at the beginning, the player must jump down to the left where the yellow balloon is (if one accidentally touches it, they will need to wait until it reappears). Then, the player must jump on the top of the balloon and walk up the wall next to it. After reaching the top of the level (which is a quarter-loop) the player can make a move like they are walking around a normal loop and move upwards. The player will get stuck there and there is no way to escape either. However, now they can move to the right and do the whole course in a very low time. The character only need to do 1 jump per lap to jump over a small gap. The collision has been fixed in Sonic 3 & Knuckles, making this cheat impossible to do in that game; however, due to S3&K using FRAM data from the Sonic 3 cartridge, records achieved using the cheat will display in S3&K.
