Eight years and seven seasons after HBO's "Game of Thrones" premiered, the wildly popular series drew to a close this year. Ardent fans who couldn't get enough of the record-breaking series have also been visiting otherworldly filming locations for years — and even if the show series has concluded, those sites are wildly popular. From Iceland to Morocco, here are five "Game of Thrones" destinations that are popular with tourists, whether or not they've ever watched the hit show.

King's Landing: Dubrovnik, Croatia

Dubrovnik's Old Town, pictured above, was a mainstay of the "Game of Thrones" as King's Landing, the capital of Westeros' Seven Kingdoms in the show. With formidable fortress walls, the city's medieval aesthetic has served the series well since its second season, and is likely to feature heavily in upcoming episodes. Unfortunately, hordes of fans descending on Croatia have threatened Dubrovnik's Unesco World Heritage status. In response, the government announced in 2017 that it plans to limit the number of tourists from cruise ships to 4,000 at any one time.

The castle in "Game of Thrones" may have been computer-generated, but the steps weren't — and that has been enough to attract throngs of tourists to a small island in northern Spain. Better known as Dragonstone to fans, San Juan de Gaztelugatxe was built as a shrine for St. John. Now, visitors are making the pilgrimage in order to walk the steps of the fictional Mother of Dragons, Daenerys Targaryen, who used the castle as a base in season seven. Authorities are reportedly considering taking action to manage visitor numbers.

Kingsroad: Dark Hedges, Northern Ireland

The Dark Hedges look and sound like they would fit right into the world that George R.R. Martin created, but they have a much less exotic name in the show — Kingsroad. It's the highway that cuts through the Seven Kingdoms in the "Game of Thrones," and ends in King's Landing. Located in Northern Ireland, the road is lined with the twisted branches of beech trees that were planted hundreds of years ago. Since October 2017, cars have been banned from using parts of the road in response to heavy traffic in the area.

Besides acting as the base camp for the Night's Watch army, the Fist of the First Men is also where an important battle takes place in the "Game of Thrones" series — a fight against winter zombies and White Walkers, the first in thousands of years. Even for non-fans, however, the Mýrdalsjökull glacier in south Iceland is awe-inspiring with its imposing cliffs. While authorities are not limiting tourists, the glacier does sit above an active volcano that occasionally halts air travel in Europe.
