Literally just got back home from Luton airport mate.
Had an amazing time - what a place. We squeezed so much into 5 days, I'm absolutely exhausted.
Highlights were driving down to Vik and the waterfalls on the way, going to the Blue Lagoon, exploring the Lava tunnels, the cathedral at Reykjavik, and seeing the Northern Lights.
Such a cool place and chill vibe. Despite everything costing three times what it does here, it was worth every penny.
Iceland should be protected at all costs as a world heritage natural place of beauty.
