(CNN)With dreamy landscapes and an out-of-this-world feel, it’s not surprising that the Golden Circle tour is considered one of the best things to do in Iceland.
Better still, especially for those using the volcanic island as a brief stopover between North America and Europe, it can be done in a day as part of a bus tour or self-drive.
There’s a downside though.
That ease of access, and the ethereal allure of this geological wonderland, means the Golden Circle can get a little busy, particularly when the tour buses arrive.
Not only that, but in following that well-worn trail, visitors could be missing out on equally stunning, but somewhat more hidden marvels elsewhere in Iceland.
To help, we’ve put together a guide to the Golden Circle that offers alternatives to the big attractions for those with extra time on their hands and adventure on their minds.
Þingvellir National Park
Thingvellir, or Thingvellir as many people pronounce it, is a national park and an extraordinary first stop on the Golden Circle tour.
Here, under what looks like the solid ground of Iceland, the North American and Eurasian tectonic plates are splitting apart a few centimeters (an inch) each year, meaning that eventually the island will be pulled in two at this spot.
ingvellir also holds cultural and historical value for Icelanders — it’s here that the Althing, the national parliament of Iceland, was established in 930 AD, making it the site of the first Viking parliament.
Sessions were held until the end of the 18th century, when the parliament moved to Reykjavik.
While it’s rugged and filled with boulders, ravines and creeks with crystal-clear water, it’s easily accessible by trails.
