Our trip starts with the black part of this popular combo tour. We'll explore a hidden lava tube cave located right below one of Iceland's many lava fields. Discover the natural marvels left by the volcanic activity in the area whilst exploring around in the dark underworld of the lava cave before heading towards Thingvellir National Park, a UNESCO World Heritage Side for the blue part of your combo tour. Snorkeling in the heavenly blue colors of Silfa fissure is simply a once in a lifetime kind of experience. Silfra is definitely one of Iceland's secrets, the fissure offers an out of this word visibility and scenary, with its crystal clear, blue waters and rugged underwater terrain.
