Tvibotni in Thingvellir National Park

Ancient two storied lava tube

Tvibotni is an astonishing lava tube in the Thingvellir National Park and it lies deep within the prominent lava field. The lava tube consists of a spacious chamber and has almost no brake down.

The Tvibotni lava tube has a great amount of beautiful lava formations. A part of the lava tube consists of a false floor, so there’s a second story. But show caution while exploring the upper floor. The cave is larger than expected for a lava tube when you enter the second half of the upper floor, for it has 10 meters width and 10 meters height from floor to the ceiling.

The entrance is a gaping pitfall and people are wised to use a ladder to get into and out of the lava tube. Many people consider the Tvibotni lava tube to be one of the most beautiful lava tubes in the Thingvellir National Park.

Extreme Iceland offers tours to the Tvibotni lava tube cave and the Thingvellir National Park every day of the year.
