How to unlock the Back to the Bayou achievement in InFamous 2 - Definitive Guide
If you stand on the cement by the water, where the orange arrow is pointing is an electricity pole. Use the Lightning Tether to pull yourself to it, then follow the path of wires and bridges all the way back to the beginning. (There's also a Dead Drop back here.)

Remember that place near the very beginning of the game where you had to bypass the military to enter New Marais? In order to unlock this trophy, you’ll have to head back there again. You CAN get back without the Static Thruster upgrades, but for the trouble it's worth, it's not worth it. Hence, it is recommended you attempt this with the upgraded Static Thrusters.
Once you’ve absorbed your third Blast Core during the story mission, along with a new power, your Static Thrusters (while in the air, ) will also be upgraded, now with an initial upward boost upon using it, as well as the ability to use it to cover more distance.
With your upgraded Thrusters, head to the northwest section of the first island. Go behind the buidling by the dock here, jump on the boat, and hover your way to that tower in the water. Once you're on top of it, its just a matter of zipping through more power lines and platforms. Once you're at the very end of this area, the trophy will unlock momentarily.
