Just off the coast of Iceland, there is a volcanic island called Surtsey. It was formed by a series of volcanic eruptions. It has been the subject of scientific research for years, as the island has evolved from a volcanic landscape that was absolutely barren of life, to a place where plants and animals are now thriving.
Due to its significance to scientific research, people are prohibited from visiting the island.
Ise Grand Shrine
Over 100 shrines dedicated to the goddess Amaterasu-Omikami are placed in this sacred space in Japan. It was built around 4 BC. Legends claim that the goddess chose this site for herself thousands of years ago due to its peacefulness and isolation. The shrine holds several spiritual and sacred objects that are of great importance, like the Sacred Mirror or Yata no Kagami.
Only for Royals
Don't waste your time trying to sneak in to see the inside. The only people granted admission are priests and priestesses of the royal family. Plus, you’d be up against the Japanese military and an intense-looking fence.
The public can see the thatched roofs of the shrine. The structure is destroyed and rebuilt every 20 years, in accordance with the Shinto belief of death and rebirth.
Not Open to Humans
Visitors would pose a risk to the natural processes happening which currently remain unaffected by outsiders. Other than various scientists who come to do research, the island is not visited by humans.
There are approximately 12 species of birds, grey seals, orcas, and some types of plants living on this volcanic island.
North Sentinal Island
North Sentinel Island is part of the Andaman Islands, an archipelago in the Bay of Bengal. On the island, you will find the Sentinelese people, one of the last groups of remote humans who remain completely disconnected from the outside world. They reject any form of modernization, living primitively, and as hunter-gatherers. The tiny island is approximately 28 square miles. You won't want to visit the island for a number of reasons. First of all, getting to the island will pose a risk because it is surrounded by dangerous coral reefs which are not on a map. And once you get closer to the island, you will face death by the Sentinelese people, who are known to act violently when outsiders approach.
Travel to the island is strictly forbidden in order to prevent the tribes-people from contracting diseases to which they aren't immune. Attempted contact has been made with the islanders in the past, but for the most part, they haven’t been successful. Beginning in the 1960s, Indian explorers landed on the island every few years to try and develop friendly relations with the Sentinelese. In the mid-’70s, things took a dramatic turn when a Sentinelese fighter shot a National Geographic film director in the thigh with an arrow.
