📍 Things to do when you land
- Drive the Golden Circle – See the rift valley of Þingvellir, the erupting Strokkur geyser and the thundering Gullfoss waterfall in one day.
- Chase the northern lights – Head away from city lights on a clear winter night to watch green ribbons dance across the sky.
- Soak in a geothermal pool – Join locals in a neighbourhood hot pot or a natural hot spring for the true Icelandic social ritual.
- Hike on a glacier – Strap on crampons with a certified guide to explore blue ice and crevasses on an outlet glacier.
💡 Tips for a cheaper ticket
Money hackEat your big meal at lunch
Many restaurants serve a cheaper set lunch menu – the same food as dinner for a fraction of the price.
Money hackKeep two cards in two places
Carry one card in your wallet and hide a backup in your bag, so one lost wallet never ends the trip.
