These incredible frozen caves seem almost otherworldly as they daylight illuminates them.
Matěj Kříž’s incredible shots reveal the beauty of the brilliant caves, but he’s also very aware of how deadly they can be.
The photographer captured the amazing shots in the Vatnajokull national park on the Breidamerkurjokull glacier tongue.
Matěj said: “One of the ice caves has been well known for few years already, but new ones appeared on east side of the glacier tongue this year.
“I live in the area for almost one year and exploring is part of my job – since I am working in the Jokulsarlon glacier lagoon, we were able to spot them from the boats in the end of the summer.
“Since my job involves cooperating with local companies, I have good relationships with them and they told me about caves hidden from tourists, chichis the crystal blue one.
“It is always dangerous in these areas, to some of them you can get on the boat and then climb on the glacier, or with a superjeep or on your own, but anything can happen at anytime of course.
“There are active volcanoes under the glacier, and earthquakes can break the entrance to the cave… or you can encounter Icelandic troll!
“The caves change every second thanks to the light, but it is just appearance during the days.
“The biggest problem is the warm weather or rain because ice caves are created by stream of the water – it is basically glaciers waste pipe.
“Iceland is magical country and the ice caves are a fantasy world all by themselves. You can admire the whole thing or focus on details hidden in the ice and find much more.”
