This is an amazing experience. Think of your wildest expectations and multiply it with 10. Þingvellir by itself is amazing but experiencing it from below sea level is "another level". Without spoiling to much, I would say that vibrant colors, are what leaves you in awe. My guide, Birgir, was absolutely amazing. Very knowledgeable og fun, but he didn't loose focus on safety. Remember to bring towel, swimsuit and underwater camera.
