Lake Plansee in Austria is a hidden gem for hikers, offering a stunning viewpoint with panoramic views of the lake and surrounding mountains. The hike is not an official trail, so finding the starting point can be a bit tricky, but the effort is well worth it. The trail is steep and challenging, but the solitude and breathtaking scenery make it a memorable adventure. Plus, the crystal-clear turquoise waters of Lake Plansee are perfect for a refreshing dip after the hike.
