Stoick: "Out there, beyond the sunset, lies the home of dragons. Legends tell of ships that sailed too close to it, only to drop off the edge of the world, never to be seen again. But those sailors who turned back told tales of a great waterfall and dragons guarding the entrance to a hidden world."
Hiccup: "Whoa."
Stoick: "Not just a nest, Hiccup, but a land from which all dragons come."[src]

The Hidden World is the major and titular location that is featured in How to Train Your Dragon: The Hidden World. It is the ancestral home of all dragons.

Official Description

The Hidden World is an old sea-faring legend about a land at the edge of the world, where many sailors have lost their ships — never to be seen again. Those who have returned reported sightings of a great waterfall and dragons guarding the entrance to a hidden world beneath the sea. A land from which all dragons hail. [src]

We wanted something that transcended the idea of a cave. Part of that was delving into bioluminescence and was of channeling light into this subterranean space with the use of crystals that could carry light from magma. We wanted it to be an exotic world that still feels like it belongs here on earth. But it's still a place for dragons and not for humans. [src]

Hidden World

The Hidden World is located within a massive volcanic caldera that serves as a gateway to an endless maze of chambers and volcanic tubes, which in turn work their way around the world.[1] This subterranean world contains bioluminescent fungi, coral and bright, scintillating crystals that adorn the huge cavernous spaces and antechambers.[1]

Notable Places

The Caldera

The Caldera is a giant collapsed volcano in the middle of the ocean, which serves as the entrance to the Hidden World. The only way to enter the Caldera is by flying in on a dragon.

Mushroom Forest

After a dragon has entered the Hidden World through the Caldera they get access to a network of caves deep in the crust of the earth. After a dragon flies through this network they reach the Mushroom Forest, where the Hidden World's bioluminescence is revealed. The Mushroom Forest mainly gives home to many stalactites and stalagmites that are completely overgrown with various sorts of mushrooms.

King Island

At the center point of the Hidden World lies King Island, which serves as the throne room for the king of dragons. The throne for the Alpha is a gigantic crystal on the island, looking over a large part of the Hidden World.

Hidden World Annex

In the darkest depths lies the unknown and it is up to Vikings to explore it! Very few Vikings have been valiant enough to venture into its depths, but those few who have get to witness the light and bioluminescent found within. As dragons seem to take a shine to these underground caves and brightly glow throughout them. [src]

Hidden World Caverns

After the discovery of Hobgobblers, Vikings have been fascinated in learning more of these incredible dragons that has led many to visit their beautiful home. Hobgobblers appear to be small, fierce, powerful dragons but they are rather mischievous in their own way, perfectly resembling the area in which they live; full of mystery and hidden surprises!

Vikings can expect these inner caves of the Hidden World to be composed of massive crystal-like structures and have numerous corals running along the open tunnels and like the Annex, a unique touch of gleaming lights can be seen all around. Vikings venturing inside will be left amazed as they watch their dragon light up inside the tunnels. It is indeed as astonishing as it sounds and perhaps that is the reason why these dragons seem to have kept the caverns hidden away from Vikings for quite a while. The caves are full of hidden mazes and tunnels that are sure to test the clever mind of a Viking, and once inside the area reveals beauty unlike anything we've seen before!

How to Train Your Dragon: The Hidden World

Stoick the Vast believed that the Hidden World is a location where all dragons come from and planned to seal it off to stop the fighting between humans and dragons.

Hiccup confided in Astrid about thinking to find the Hidden World so that everyone in their tribe could live in peace amongst the dragons, and then told the Hooligans that they would go there. The pair eventually discovered it while searching for Toothless on Stormfly before being chased out by the dragons that reside there, which made Hiccup realize that humans would never be welcomed in the Hidden World.

Following the death of Grimmel, the Grisly and the defeat of the Warlords, Hiccup and the rest of the Hooligan Tribe decided to send all of their dragons to the Hidden World, so that no human could ever find and harm them.

Sailing to the Hidden World

About a decade later, Hiccup and Astrid take their two children, Zephyr and Nuffink, to the entrance of the Hidden World, where they find Toothless, the Light Fury, Stormfly, and the Night Light hatchlings. The family travels there by boat, indicating that the Hidden World is not that far from New Berk.


School of Dragons

The Hidden World appears in School of Dragons in "The Hidden World" expansion. Specifically, a section called the "Hidden World Annex" appears on the School of Dragons Island.

Later, another entrance is revealed on New Berk, containing a Hobgobbler nest, in the "Curse of the Hobgobbler" expansion.

Dragons: Rise of Berk


The Hidden World first appeared as a special searchable location in December 2018.

Hidden World Searches


In 2019, the Light Fury was released in the game as a searching dragon similar to Toothless. She is able to search the Hidden World for specific dragon individuals at certain levels.


  • The Hidden World is a famous myth/legend from the distant seas. It is sometimes called "a world beyond the sunset".[2]

  • The entrance to the Hidden World appears similar to that of the Bermuda Triangle since it is a great hole in the sea with fountains of water pouring into it.
  • Dean DeBlois first imagined the Hidden World in a dream as a hole in the sea.[2][3]
