I need help with a present?

A good friend and girl i like alot is having a birthday in less than a week. I need help with a present. She loves the outdoors. Before anyone says anything about waiting to long i have a good reason. Im in the military, have been in training and didn't expect to be back yet. I know it depends alot on the girl but i didn't figure it could hurt to ask. Right now im leaning towards skydiving
