The bruised knees have healed, but Brogue’s sense of adventure, and love of climbing trees, remains, so it’s little surprise the 7th Room Treehouse, in the Lule River Valley, Sweden, has gone straight to the top of our must visit list. As you approach from below, the entire underside is covered by a life size photograph of the treetops, just as they looked before the space was constructed, cheating the eye to what lies above. Climb 10m up and discover a breath-taking view of the Lule River and vast panoramic windows, designed to give visitors uninterrupted views of the unforgettable northern lights. Two beds, 75 square meters of classic modern Scandinavian living space will finally drag you in from the cold, unless you choose to sleep under the stars on the net, suspended high above the forest floor.
