Travelling (obviously :D ), visiting new places, learning about different cultures & meeting people from around the world and having fun
Horseback riding (and generally just spending time outdoors, especially if there are animals involved)
Baking and cooking with friends
Wildlife medicine, Wildlife Rehabilitation and Conservation (not really a hobby, I suppose, but just something I'm interested in)
There are so many! And even more places I'm sure I'll love once I get there!
