Billionaires don’t just visit islands, they buy them. These ultra-wealthy collectors snap up private islands around the world like normal people collect coffee mugs.

Why settle for first-class when you can leave Earth entirely? The richest people in the world are booking tickets on private spacecraft for quick trips to the edge of space. These cosmic adventures cost hundreds of thousands to millions of dollars for just a few minutes of weightlessness and an incredible view. Some forward-thinking billionaires have already put down deposits for future lunar orbit missions and space station stays.

Submarine Exploration

Forget scuba diving—billionaires prefer exploring the ocean depths in personal submarines. These underwater vessels cost millions and let owners explore shipwrecks and marine life without getting wet. Custom-built submarines can dive thousands of feet below the surface, reaching parts of the ocean most scientists rarely see. Some luxury subs even feature transparent hulls, underwater cameras, and robotic arms for collecting samples.

Ancient Artifact Collections

The ultra-wealthy often develop a taste for owning pieces of history that museums can only dream about. They build climate-controlled rooms in their homes to display ancient scrolls, statues, and jewelry from fallen empires. Private dealers and auction houses cater specifically to these collectors, offering items that can cost tens of millions for a single piece. Some billionaires even hire former museum curators and archaeologists to manage their collections full-time.

Vintage Car Racing

Regular car collectors buy classics to look at them—billionaires race them. These wealthy hobbyists spend millions restoring vintage Formula 1 cars and other historic racers to their original glory. They hire professional pit crews and rent entire racetracks for private racing events with their equally wealthy friends. Some even build private race circuits on their own property, complete with garages full of mechanics to keep their vintage speedsters running perfectly.

Mega-Yacht Building

For some billionaires, owning a yacht isn’t enough—they need to design and build their own floating mansions from scratch. These custom vessels can cost upwards of $500 million and take years to complete, with features like helicopter pads, submarine garages, and multiple swimming pools. Owners often employ full-time crews of 50-100 people just to maintain and operate these floating palaces. Some mega-yachts are so large that they require their own support vessels just to carry all the toys and extra supplies.

Wildlife Conservation

The richest nature lovers buy up entire ecosystems to protect them. These conservation-minded billionaires purchase thousands of acres of rainforest, savanna, or coral reef to create private nature preserves.

Extreme Helicopter Skiing

Regular ski resorts are far too crowded for the ultra-wealthy who prefer being dropped on untouched mountain peaks by private helicopters. These thrill-seeking billionaires buy custom helicopters equipped with special ski racks and hire former Olympic skiers as guides. They claim entire mountain ranges as their personal playground, often flying to different countries just for a weekend of perfect powder. Some even purchase private mountains to ensure they never have to share the slopes.

The ultra-rich have moved beyond simply collecting art – they commission entire installations created just for them. These massive custom art pieces can cost tens of millions and often require rebuilding parts of mansions to accommodate them. Famous artists may spend years creating these one-of-a-kind works that will never be displayed in public galleries. Some billionaires even hire architects to design entire buildings around their commissioned art pieces.

Private Concert Series

Why fight crowds at concerts when you can bring famous musicians to your home? Billionaires regularly pay millions to have chart-topping artists perform intimate shows in their living rooms or private venues.

These wealthy sports enthusiasts spend billions acquiring professional franchises in football, basketball, baseball, and soccer. They build state-of-the-art stadiums and training facilities, often naming them after themselves or their companies.

Some eccentric billionaires have taken to building temporary luxury hotels made entirely of ice and snow. These frozen palaces cost millions to construct each winter in remote arctic locations, only to melt away months later. Owners fly in master ice sculptors from around the world to create intricate frozen artwork throughout these exclusive retreats. They provide heated sleeping bags made from materials that cost thousands per yard to keep guests comfortable in below-freezing temperatures.

Micronation Creation

The ultimate hobby for control freaks with unlimited funds is creating their own tiny countries. These self-declared micronations are usually built on artificial islands or remote land purchased specifically for this purpose. Billionaire “rulers” design their own flags, passports, and sometimes even currencies to distribute among citizens (usually friends and family). Some have spent billions on infrastructure like private airports, power plants, and communication systems to make their micronations genuinely self-sufficient.

Haute Couture Collecting
