Castle Ward is a real-life castle built in the 18th century. The property is open to the public year-round.
It looks like winter has come to Cairncastle, the location used to film scenes taking place outside the walls of Winterfell.
Even farther north, Vatnajokull National Park in Iceland contain stunning mountaintops and glaciers.
Another Icelandic location used was Svinafellsjokull, with more snowy ridges and icy ground to utilize.
Let's head to the coast. Ballintoy Harbor, on the coast of County Antrim in Northern Ireland, is a small fishing haven.
In season two, the harbor was transformed into Pyke of the Iron Islands — home to Theon Greyjoy and his family.
Larrybane Bay is another coastal landmark you can explore on the app. The limestone cliffs serve as the Stormlands on "Game of Thrones."
The bustling city of Dubrovnik in Croatia has become a hot destination in the years since "Game of Thrones" premiered.
Scenes from King's Landing are filmed there. Producers even kept the red-tiled roofs as a city-feature.
The Dark Hedges are a well-known attraction located in Stranocum, Northern Ireland. The beech trees were planted by an 18th century family.
Jorah and Tyrion's dangerous venture through Valyria was created using the canal to film the boat's slow progression. Details were later added with CGI.
Murlough Bay, also in Northern Ireland, is the perfect setting for the fictional Slaver's Bay — note the sharp cliff face in the background.
Voila! Scenes of Tyrion and Jorah getting captured by slavers were filmed in Murlough bay for season five.
Another area you can virtually tour on the app is Quintin Bay, home to Quintin Castle, built in 1184.
For season five's location of Stokeworth, and this scene featuring Bronn and Jaime, Quintin Castle was given a bit of a visual effects upgrade.
"Game of Thrones" producers used it as the backdrop for Riverrun, Catelyn Stark's childhood home featured in season three.
The sand dunes of Portstewart Strand, located on the north coast of Northern Ireland, serve as the series' southernmost fictional location in Westeros: Dorne.
The royal grounds were an idyllic representation of the Water Gardens of Dorne, where Princess Myrcella and Prince Trystane spent their days.
The interior of the palace is just as exciting as the exterior, with elaborate mosaics and tiled floors.
The Shillanavoghy Valley, near Slemish Mountain in Northern Ireland, was the perfect choice for the Dothraki grasslands of Essos.
When Drogon landed Daenerys on this cliff side in season five, she could see nothing but the Dothraki sea.
Daenerys wandered below the sharp cliffs in the season five finale, and is eventually found by an enormous horde of Dothraki.
After added visual effects, the bridge was transformed into the street markets of Volantis for season five.
