The blue ice caves in Iceland are about to disappear. If you don't come now, you'll miss them...

See the 100th shade of blue in the world. If you visit Iceland in winter, you absolutely cannot miss the blue ice caves. According to the ice cave guides, the blue ice caves in Iceland will disappear in the next 25 years. As a special activity that can only be done in winter, you cannot visit the ice caves on your own. You must join a tour group and follow a guide to a designated meeting point. The guide will then drive you across the snowfield to the entrance of the ice cave. This is also to protect the natural environment. I visited the ice cave of Vatnajökull, the largest glacier in Europe. Because the ice and snow meltwater backflows in summer, the ice caves are re-excavated every winter, so every view is a limited edition! 3. The tour fee for the ice caves is relatively higher than for glacier hiking. But it's still very worthwhile! There are several time slots for visiting the blue ice caves in a day, and the whole trip takes about 3 hours (including the round-trip drive). I recommend choosing a time slot around 11:00–14:00, because in winter in Iceland, the sun rises at around 10:00 am. At this time, the light is not strong, and the blue ice in the cave looks better when it is translucent. There are more tourists in the afternoon, and it is difficult to take good photos in the crowded ice caves. The sun starts to set at around 4:00 pm. We visited two ice caves, one was ice blue and the other was black. It is said that the darker the color, the older the ice cave. The black ice cave is not very translucent. If you look closely at the ice layer with a flashlight, you can see thick volcanic ash, which shows that this is a dry ice cave. The guide will kindly tell you how to take photos, which position is good for taking photos, and even prepare a lantern for you as a prop. You still need to wear crampons to enter the ice cave, so remember to wear hard boots. As for clothing, it is not very cold in the ice cave. You can take off your coat when taking photos and put it back on after taking photos. It won't be very cold, so try to wear waterproof clothing.
