Adventure seekers and wellness travellers can add the Arctic Bath Hotel to their bucket lists. Opening in the fall of 2018 in Swedish Lapland, the hotel is set to ‘float’ on the Lule river as customers enjoy luxurious spa treatments. If you want to be adventurous, dive into the open-air arctic plunge pool right in the centre that will remain open all year round. While the crisscross log exterior of the hotel pays tribute to the country’s major forest industry, this floating hotel is best visited during the Northern Lights. From SEK 5,500 doubles.
