Scuba Diving! It's a really cool sport! It's different then your average sport and a great experience! I'm the same age as you and I'm also a girl and I love to dive! Classes are sorta expensive, but if you rent your gear, it's super cheap! It's not hard to find places even if you live far from any oceans! I live in Minnesota! I just scuba dive in lakes! My friends all suggest it's not a sport, but swimming is a sport! Swimming with 20-50 lbs of equipment on your back should be a sport, too! It's super fun and a great experience! I suggest you give it a try!
