During our unforgettable 9-day campervan road trip around Iceland, we chased countless waterfalls, explored volcanic craters, stood on massive glaciers, and walked on beaches in every shade imaginable. Iceland’s raw beauty is unmatched, but one experience completely surprised us and became a highlight of the trip: snorkeling between two continents at Silfra Fissure in Þingvellir National Park. This wasn’t just another adventure; it was a once-in-a-lifetime chance to float in crystal-clear water right where the North American and Eurasian tectonic plates meet.
