Most sights on the Kamchatka Peninsula, a volcanic Eden that stretches for 800 miles in northeastern Russia, are inaccessible except for by helicopter. The region boasts at least 300 volcanoes, 10 percent of them active, and is mostly unspoiled wilderness with abundant eagles, orcas, bears, and salmon
This Norwegian archipelago in the Arctic Ocean has at least as many polar bears as people and is home to the Global Seed Vault, meant to help restore the world's crops in case of widespread disaster. The town of Longyearbyen, the world's northernmost permanently inhabited community, gets 24 hours of sun in the summer, but 24 hours of darkness in the winter.
While Bora Bora is certainly a popular destination, it's still off limits for all but a fraction of vacationers due to sheer expense. This Tahitian island known for its over-water bungalows is one of the priciest, most far-flung destinations in the world, and an average hotel room once clocked in at 855 dollars a night.
These remote, self-governed Danish islands halfway between Norway and Iceland are certainly off the beaten path. Sheep outnumber people, but there are plenty of craggy mountains, turf-topped houses, puffins, and tumbling waterfalls (including the stunning Mulafossur) to make the trip worthwhile.
The Acacus Mountains are a dramatic corner of the Sahara carved by desert winds and abrupt floods. The remote area in southwestern Libya, also known for pictographs dating back as far as 12,000 B.C., is reachable only by 4x4, and Libya remains largely off limits to most tourists because of terrorism and civil unrest.
Easter Island's popularity with tourists belies just how remote it is: a staggering 2,200 miles from the coast of Chile. It's also the closest landmass to Point Nemo, the point in the Pacific Ocean farthest from any land. Still, this small dot in the Pacific draws visitors eager to see the hundreds of mysterious moai, statues carved by indigenous people close to 1,000 years ago.
Dunes as far as the eye can see make up the Rub' al Khali, otherwise known as The Empty Quarter, which stretches over a third of the Arabian Peninsula, including vast swaths of Saudi Arabia, Oman, Yemen, and the United Arab Emirates. Many of its 250,000 square miles remain unexplored, and it's the largest area of continuous sand in the world.
These Island Vacations Don't Require a Passport. Once bustling with tourists, half of the Caribbean Island of Montserrat is a strictly controlled exclusion zone after a series of volcanic eruptions buried the region in the late '90s. The island's capital, Plymouth, is now a modern-day ghost town covered in ash, and the Soufriere Hills volcano continues to erupt to this day.
A third of the plant life on this 'most alien-looking place on earth' in the Indian Ocean is unique to the island, part of Yemen, according to Atlas Obscura. That includes the umbrella-like dragon's blood tree, probably the most iconic example. Roads are few and far between here, and most travel to turbulent Yemen has been a no-go for U.S. citizens for quite a while.
The Amazon is so large, it could be home to as many as 50 tribes that have never had contact with the outside world. The river itself snakes nearly 4,000 miles from mountainous Peru to the Atlantic, and some of the vegetation surrounding it is so dense that it takes up to 10 minutes for rain to reach the ground. 
The worlds second-tallest mountain is nicknamed the Savage Mountain for good reason: It's far more difficult than Mount Everest to climb, with mind-boggling steep cliff faces, and a location so remote that just getting there is an expedition in itself. Nearly 30 percent of climbers die trying to reach the top, compared with 4 percent who try to summit Everest.
There's a reason Napoleon was exiled here: This volcanic island, a British territory in the South Atlantic, is a staggering 1,200 miles from southwestern Africa, the nearest stretch of continental coastline. Until late 2017, the island was reachable only by a five-day voyage from Cape Town, but it now has an airport, nicknamed 'the world's most useless.'
