- For the Sonic Jump level, see Jungle Zone (Sonic Jump).
Jungle Zone is the third Zone in the 8-bit version of Sonic the Hedgehog. As with other Zones in this game, this Zone consists of two standard Acts followed by a shorter third Act which contains the Zone's boss.
Like Bridge Zone, this Zone is also unique to the SMS/GG game. Set within a lush, green jungle filled with exotic plants as well as the troublesome Badniks, Sonic will have to get across a dark, limpid river by jumping across platforms and running along vine bridges. Throughout Act 1, Sonic can hop across logs that are cascading down waterfalls, and will even have to run along on rolling logs to cross the Chopper-infested waters.
The second Act sports an unusual type of level structure as the Act is built vertically rather than horizontally, where Sonic must climb up a giant waterfall by jumping from platform to platform. In the Master System version of the game, the player is not allowed to go back down the waterfall, and attempting to do so will cost a life. This does not apply to the Game Gear version as the player will just fall down to the lower levels, so it is safer to make mistakes.
||At the foot of the rocky mountain is a jungle of densely-packed trees. A great waterfall blocks your way. If you don’t ascend it, you won’t be able to reach Eggman.!

||Wild flowers and exotic plants surround you in the damp, dark jungle. When you reach the turbulent waterfall, watch your step! One false move and you're gone for good!

||Spikes — Crab bot that shoots fireballs from its pincers.
||Chopper — Jumps up from the river to try and bite Sonic.
||Newtron — Materialises in sheltered areas to shoot a projectile, then disappears.
Special item locations
The following are the locations of the Chaos Emerald and 1-Up monitors in each Act. Detailed maps featuring the locations of these items can be found here.
The Chaos Emerald for this Zone is located in Act 1. After riding the first log across water, cross the spiked log bridge, then ride the falling log at the waterfall down near the river, then jump to the left and ride a floating log to the left to find the Emerald.
- Act 1: Located at the first waterfall in the Act. Jump from the vine and onto the platforms, then jump up to the monitor.
- Act 2: In the Master System version, the monitor is located just before the final spiked log bridge of the Act, though care should be taken when breaking the monitor as it conceals a spring that will launch the player into the bottom of the screen. In the Game Gear version, the monitor is located shortly before the checkpoint, and the player must carefully jump over spiked logs to reach it.
- Act 3: Located in the water, just to the right of the starting point.
