This relatively unknown town in Florida has become a playground for the richest of the rich

Every winter, the small town of Wellington, in southeast Florida, experiences a tremendous influx of some of the wealthiest people in the world.

From the Springsteens to the Bloombergs, to the families of Steve Jobs and Bill Gates, to Arab sheikhs and South American billionaires, it's a congregation of people with spectacular quantities of money.

No, they aren't gathering for some sort of business affair. They're coming for WEF: the Winter Equestrian Festival, which takes place every year from January to April on the hallowed grounds of the Palm Beach International Equestrian Center. The 12-week WEF has been the longest equestrian event of its kind for several years running, and it attracts riders at all levels of the sport.

Because of the costly nature of all things equestrian, it's no surprise that rich people and horses go hand in hand. But while some wealthy riders and owners are just in it for the glamour and prestige, some - like Georgina Bloomberg and Jessica Springsteen - are serious and successful competitors.

As WEF has grown over the years, it has turned Wellington into a winter oasis for the upper crust, who come to ride, mingle, and bask in the warm weather. But while the human amenities are nothing to sneeze at, the real luxuries are reserved for the horses. Here's an inside look at this star-studded fantasy world, where celebrities come to play and their four-legged companions reign supreme.
