Possible: travel to Antarctica, Scandinavia, New Zealand etc. Go skiing or snowboarding. Swim in a beautiful place/with dolphins or something. Go paragliding. Learn circus skills. Go skydiving (or in one of those wind tunnels where you don't have to jump out of a plane). Having more than enough money.
