Plumb the depths of Iceland’s hidden underwater and underground worlds, with this combo tour of scuba diving and lava caving. This tour should not be missed by any seeking a unique adventure, as it combines two rare and thrilling experiences into one.

Which tour you will do first depends on conditions. Presuming you snorkel first, you will be picked up from downtown Reykjavík early in the morning, and be driven forty minutes to Þingvellir National Park. This is home to Silfra fissure, your dive site.

Þingvellir is located directly between the Eurasian and North American tectonic plates. The tension caused as they pull apart rips ravines open in the park, and, as there is a lot of water running underground from Langjökull glacier, these ravines fill up. 

Due to the long underground filtration process, the water in Silfra emerges incredibly clean; not only is it drinkable, but you will be able to see further than 120 metres. Because this is some of the best naturally occurring visibility that can be experienced on a scuba dive, Silfra is considered one of the world’s greatest dive sites.

Your guides will brief you on your route, help you into your gear, then lead you to the staircase into the fissure. The half-hour to forty minutes you will spend in Silfra will no doubt stay with you for life; the depth of the blues, the scale of the ravine, and the clarity of the water are nothing short of mesmerising.

After hot chocolate and cookies to warm up with, you’ll return to your van, and make your way to the Reykjanes Peninsula. This land of lava landscapes has hundreds of caves hidden beneath its surface, but the one you are heading to is no doubt the most stunning: Leiðarendi.

This cave is, in fact, composed of two lava tubes from separate eruptions one and two millenniums ago. It curves in a circle for hundreds of metres, with features such as stalagmites, stalactites and, throughout most of the year, ice formations. These highlights, along with the vivid colouration of the rocks, make for a fascinating walk.

Leiðarendi, however, is not like many other caves, which have pathways and lights. It is entirely natural, so traversing will require a degree of crawling and clambering. Though a little daunting at times, this only adds to the adventure of the trip. Just be sure not to wear anything that you value, as torn clothing is not uncommon on caving trips here.

Once the cave has been explored, you’ll return to the surface world, and be driven back to Reykjavík.

Take two unique adventures in a single day with this underwater and underground combo. Check availability by choosing a date.
