You won't find India's Taj Mahal or San Francisco's Alcatraz on Smithsonian magazine's list of 25 top new places to travel in its September issue. It approaches destinations as a place to learn and experience rather than just snap a photo.
Smithsonian calls it a life list -- more about living than kicking the bucket. And it's geared toward the 21st century traveler. Four U.S. destinations make the list, and five sites don't even exist yet.
Check out Smithsonian's "21st Century Life List: 25 Great New Places to See" by Jamie Malanowski.
Here are the 25 that made the cut.
1. Hang Son Doong cave, Vietnam

The cave, believed to be the largest in the world, has been open to tourists for the past two years. Its entrance was only discovered in 1991, was then lost and then rediscovered. A river runs through this massive cave whose chambers can be as much as 450 wide and 600 feet deep. It's about five miles long, so go with a guide.
2. CERN Laboratory, Switzerland

Its big claim to fame is being the place where experiments led to the discovery of the Higgs bosun or God particle. And if you don't get particle physics, brush up before you go. The center, known by its acronym for Conseil Europeen pour la Recherche Nucleaire (European Organization for Nuclear Research), only occasionally schedules open days for the public to visit. It's located in Meyrin, north of Geneva.
3. Spaceport America, New Mexico

If you want to take a $250,000 commercial flight into outer space, this is probably where you'll take off and land -- with a little bit of weightlessness on your return. Richard Branson's Virgin Galactic space travel venture chugs on in Mojave, Calif., despite the setback of a fatal pilot crash last year. Spaceport offers daily tours at the site about 55 miles north of Las Cruces.
4. Mountain gorilla treks, East Africa

Travelers see the big animals close up on these treks in Congo and Rwanda. It's the close contact that makes this experience list-worthy. Smithsonian offers this tip on how to act when you see one: "Speak quietly; stay at least 20 feet from the animals; if one charges, crouch down slowly, avoid eye contact and wait for the animal to pass. In other words, act as if you were taking your tween daughter to a One Direction concert." Cost is about $400 a day in Congo and $750 in Rwanda, the magazine reports.
5. ALMA telescope, northern Chile
(European Southern Observatory)
It's the clearest view of the night sky you'll ever get. That's because this array of telescopes sits above the Atacama Desert, one of the driest places on the planet. Formally called the Atacama Large Millimeter/submillimeter Array, the telescope sits at 16,570 feet above sea level. Parts of the site are open to tourists -- and don't forget to stand still at night and just look up.
The rest of the best ...

The ice caves exist under the Mendenhall Glacier (which is melting) in Tongass National Park.
7. Ferrari World, Abu Dhabi

The theme park boasts the world's fastest roller coaster -- 0 to 60 mph in 2 seconds and a top speed of 149 mph in five seconds.
8. Cayman Trench, Caribbean Sea
You can dip 2,000 feet below the sea aboard a submarine operated by the Roatan Institute of Deepsea Exploration.
9. Museum of Islamic Art, Qatar
I.M. Pei designed this museum with textiles, manuscripts, ceramics, jewelry and more in Doha.
10. NOMA restaurant

Quite simply the world's best restaurant, located in a warehouse in Copenhagen. Chef Rene Redzepi forages and creates extraordinary dishes -- in the kitchen and on the plate.
