  • Overview & Itinerary


    Go spelunking in the wondrous lava tube caves and craters of Iceland and relax in the mystical waters of the Blue Lagoon.

    You can opt just to explore the caves, or add on the Blue Lagoon option, which gives your day a combination of thrills and repose in equal measure.

    As you make your way through the caves, behold fearsome stalactites that sparkle on the ceiling and many-colored rock formations sculpted by the dual artists of time and pressure.

    The caves are unsullied by handrails or installations, allowing you to explore them in all their harsh and exacting beauty.

    A knowledgeable guide and first-class equipment make for a safe and illuminating adventure.

    This tour lets you wind down after your caving adventure at the Blue Lagoon, a tranquil geothermal spa where you are treated to an afternoon of complete ease.

    The basic version of this tour does not include entrance to the Blue Lagoon. Availability at the Blue Lagoon can be limited therefore we recommend you upgrade to include one of our bathing packages. The Blue Lagoon Standard Bathing Package includes entrance to The Blue Lagoon spa. You can also opt for the Blue Lagoon Comfort Bathing Package, which also offers use of a towel, a drink of your choice, skin care trial pack and an algae mask.

    You will be picked up by bus from your hotel/guesthouse in Reykjavik by an English-speaking guide that will lead you through the otherworldly caves and craters of Iceland, and to the relaxing Blue Lagoon.

    Drive one hour outside Reykjavik to some of Iceland’s most spectacular lava tube caves, among geology’s most peculiar and magical masterworks.

    When a red river of lava spews out of a live volcano and begins to harden into rock, there remains beneath the surface a tubular flow of lava. These underlying lava tubes leave in their wake a cave that can endure for millions of years.

    Enter these incredible caves, where natural stalactites hang from the ceiling, and evocative rock formations of unusual colors wait around every corner.

    Respect for nature and safety are of paramount importance on this tour. There are no handrails, lights or pre-installed tools in these caves; you will see them as they have stood for millennia, with the help of equipment provided by your guide.

    Sometimes the cave floor is even, the walls are wide, and the ceiling is high. At other times, you will have to navigate irregular surfaces and proceed through low-ceilinged passages that require you to be on all fours.

    Through it all, this tour will challenge the body and excite the imagination.

    This tour lets you wind down after your caving adventure at the Blue Lagoon. The lagoon is a unique geothermal spa situated in the youngest lava field in west Iceland. Once there you are treated to perfect serenity - walk through the enchanted lava fields that surround the lagoon, bathe in the steamy blue-green waters, relax in a geothermal steam bath or release the stress from your shoulders under a soothing waterfall.

    Your time at the Blue Lagoon is at leisure. You have two Blue Lagoon bathing packages to choose from - Standard Admission Bathing Package orComfort Admission Bathing Package.

    The Standard Admission Bathing Package includes the visitor pass as well as the entrance fee to the Blue Lagoon spa. You can bathe in the lagoon, enjoy sauna and use the changing facilities.

    The Comfort Admission Bathing Package includes all the elements of the standard package and additional benefits, which are as follows:

    • Get a large and comfortable towel. You must return the towel after bathing.
    • Enjoy a drink of your choice at the Blue Café or the Lagoon Bar.
    • Get a skincare trial pack that consists of a 30ml tube and one complimentary sample of Blue Lagoon signature products. The pack also has a sample of the Blue Lagoon algae mask.

    You will be dropped back at your hotel in Reykjavik at tour’s end.
