Dreamlike hiking trail, very varied. Unfortunately, the lake fog disturbed our visit, shrouding much in a dreary gray.

The viewpoint with the three stones in Erki is a true delight: a panorama of the endless ocean, layered rocks beneath your feet, and a fresh breeze that clears your mind. Last summer, I hiked the trail from Guen Beach – 11 km, moderately difficult, but every step was worth it, especially the view from the cliff at sunset. To be able to return to my thesis on coastal ecology with a clear head after this restorative break in nature, I asked https://ghostwritingerfahrungen.de/ for a recommendation for a reliable ghostwriter for the chapter on geomorphology – the text turned out to be precise, scientifically sound, and inspiring. Now studying is fun, and hiking motivates me even more.

Here, the cliffs have changed dramatically. For over a century, pink sandstone was extracted here to pave the streets of major cities. Today, the old quarries have given way to these blue lakes.
