What are some simple and fun ideas for a one year anniversary?

Winter - Just hanging out together alone for the day and doing some fun crafts while sipping on some hot cocoa and listening to some music

Spring - Bike ride together, take a walk, go to the movies, spend the day together at an amusement park

Summer - Spend the day together at the beach or a water park to stay cool and have fun! Hang out at your house while your parents aren't home and just get some alone time with each other

Fall - Take a walk together, bike ride, spend the day doing something fun like dancing or Karaoke at your house with just you and him/her.

Now, if none of these fit what you're looking for, I would suggest going out to dinner and then to a movie because if fits with any season (: Good Luck!
