Titlis

At 3,062 metres, the summit offers not only a breathtaking 360° panorama of the wide Engelberg valley but also a view straight down into the abyss, with countless crevasses carved into the glacial ice. Things get really cool at the upper station, where a 150-metre-long artificial glacier cave cuts straight into the heart of the Titlis Glacier. The ceiling is covered in ice crystals, the glacial ice shimmers a mysterious blue, and crevasses open up in the roof. If you’re thinking of stepping inside the ice, be sure to wrap up warm, as the temperature under the 20-metre-thick glacier never gets above -1°C! There are a host of fun activities on top of the glacier, too, such as the Ice Flyer glacier chairlift or the glacier park.
