Lapporten (Swedish: "The Lapponian Gate") or Tjuonavagge (Northern Sami: ÃÂuonjávággi, "Goose Valley") is a U-shaped valley located just outside Abisko National Park in Lapland in northern Sweden, one of the most familiar natural sights of the mountains there. The valley is bounded to the southwest by the mountain NissuntjÃÂ¥rro (1,738 m) and in the northeast by TjuonatjÃÂ¥kka (1,554 m). In the middle of the valley lies Lake ÃÂuonjájávri, 950 metres above sea level. The terrain is easy to walk, but has no marked trail. Lapporten is in the NissuntjÃÂ¥rro Natura 2000 site. A world record in highline was set by 4 Germans crossing the distance between the mountains on a slackline more than above ground.
