About the Golden Circle ice cave monster truck tour
This is a long day that packs in both the Golden Circle and a glacier ice cave, so it suits travellers who don't have time for two separate trips. Pick-up is from Reykjavík in the morning, and the day covers Þingvellir National Park, the Geysir geothermal area with Strokkur erupting every few minutes, and Gullfoss waterfall, before heading up to Langjökull glacier for the ice cave section.
At Langjökull, you transfer into a purpose-built glacier monster truck, which handles the snow and ice on the way up far better than a standard vehicle. From there it's a short walk to a natural ice cave known for its deep blue colour, where your guide leads you through and explains how the cave formed.
Because it covers so much ground, this is a long day: around 11 hours door to door. It runs in winter only, roughly November to mid-April, when the ice cave is safely accessible. Walking at each stop is easy, so it suits most fitness levels, but the day itself is a full one, so pace yourself and expect some time simply travelling between stops.
