Leidarendi lava cave

Leiðarendi lava cave is a prime example of Iceland’s volcanic caves. The cave formed when a lava flow from a volcanic eruption gradually cooled on the outside. Underneath the crust, liquid rock kept moving until it drained away thus forming tunnel below the surface.

It takes just a half hour ride from Reykjavik to reach this hidden gem on the Reykjanes Peninsula. Once we arrive, get prepared for an eerie adventure! We will walk through a moss-capped lava field to a pitch-black hole. When in the cave, vibrant colors and unique rock formations take your breath away. Stunning stalactite structures hang from the ceiling, and stalagmites rise from the floor of the cave.

Though the lava tube cave gets tight at some points and might require a little bit of crawling, your efforts will be rewarded with unparalleled subterranean beauty. In winter, you even have a chance to spot icicles hanging together with other mind-bending formations.

The Blue Lagoon

After the caving activity, we will transfer you to the Blue Lagoon resort, the most popular attraction in Iceland. The thermal bath is famed for its milky blue waters and quirky history. It appeared quite unexpectedly when a geothermal power plant filled a lava field with run-off water that was unsuitable for heating systems. Since the water was hot and rich in minerals, it became a perfect place for a replenishing swim. The brilliant turquoise color is due to the silica and algae present in the water.

Today this iconic destination is famed for its curing properties. You will be able to have a luxury soak in hot water surrounded by the lunar-like landscape of the Reykjanes Peninsula. Just don’t miss out on the famous Blue Lagoon’s face mask of silica mud!


After the caving tour, we will stop for a lunch break at BSI Bus Terminal in Reykjavik. There is a cafeteria where you can try out some traditional Icelandic dishes or feel free to bring your own lunch.
