Arctic is the LEGO City line for polar explorers, and it goes back to the Town Arctic sets of 2000. The City version has come in waves with a story each time. In 2014 the explorers set out across the ice from a base camp, with an icebreaker and a supply plane, and in 2018 they found a woolly mammoth frozen in the ice and moved it out with a crane and an air transport. From 2023 Arctic joined City's explorers, with a research ship, a submarine and a mobile lab for studying the sea and its animals, and the 2025 sets added an Arctic polar train. Polar bears and huskies turn up in most waves.
