Preheat the oven to 350°F and line a large baking sheet with parchment paper. In a large bowl, mix together oats, coconut flakes, pecans, pumpkin pie spice, pepitas, and salt until all ingredients are evenly combined.
In a separate small bowl whisk together maple syrup, oil, and vanilla extract. Pour this liquid mixture over the dry ingredients in the large bowl and mix until everything is evenly coated.
Spread granola onto a prepared baking sheet, making sure to press it down slightly so that it sticks together when cooking.
Bake in preheated oven for 30 minutes, stirring halfway through to prevent burning. Once the granola has reached a golden brown color, remove it from the oven and let cool before serving.
