Fibonacci Reminder

Hello everyone!

I am writing a oneshot essentially set in the Zhangjiajie National Forest Park. My character is so surprised and overwhelmed by what he is seeing that I am introducing his senses one by one, but I couldnt quite imagine what it would smell like being in his position.

I know its quite humid, so thats probably the bulk of the experience, but are there any other, more subtle undertones I could include to make the scene feel more alive?
Even if you havent been to the exact location, any experience in a subtropical, humid climate would already be quite helpful.

Thank you!
