In October, a new ice cave called Neptune Ice Cave was discovered on Langjokull, Iceland’s second-largest ice cap. Hekla Tang from Arctic Adventures found the cave, which was formed by meltwater and shifting ice. Inside, there is a large chamber of clear blue ice mixed with volcanic ash. The company later widened the entrance and added lighting.
The cave, named for its deep Neptune-blue color, is now open to visitors. It looks different in winter and will likely melt by the end of spring.
Arctic Adventures is offering snowmobile tours to the cave until April 2026. Tours start in Reykjavik, about two and a half hours away, and include a Super Jeep ride into the Highlands followed by a guided snowmobile trip over Langjokull. All safety equipment is provided, and no previous snowmobiling experience is needed.
Travelers already in the area can join tours from Skjol Campground near Gullfoss. Tours last between 4 and 10 hours, or up to 16 hours if you add a northern lights experience. Participants must be at least 8 years old and have a basic level of fitness.
Prices start at 306 per adult, which includes a guide and transport from Reykjavik. Visitors can also add stops at other Icelandic attractions, like geothermal baths, waterfalls, and national parks.
