As you venture into Khao Sok National Park, you’ll find yourself surrounded by one of the oldest rainforests on Earth. The park’s rich biodiversity, nurtured by its limestone karst landscape and abundant rainfall, creates the perfect environment for an incredible variety of fungi. Throughout the forest, you’ll encounter clusters of wild mushrooms in all shapes, sizes, and colors — from delicate white caps peeking through the leaf litter to vibrant red and orange fungi growing on fallen logs.
