In Gothenburg, there exista the Universeum. It’s a giant indoor mountain, and educational nature walk. We checked it out today, and yeah, it’s pretty amazing. From the ground level, we took tge funicular up to the top, and then wound our way back down the mountain on the long winding trail. We went through the desert zone, arctic zone, lake zone, aquarium zone, and ended in the rain forrest. Fantastic!
