Mine is autumn because of different reasons:
- It is not so hot anymore but also not so cold.
- I really love the colorfull trees.
- It is usually the time where I make my vacation (in summer, people with children have the priority which is also understandable since the children are in school)
- I have no problems with allergy like in spring.
- it is in my opinion the best season for hiking (because of the already named reasons).
