We started our train journey from Chur, the oldest town in Switzerland .It was a beautiful day. The train journey was just amazing, the scenery is stunning , from the high towering mighty glaciers , and lakes below , the countless castles perched in the mountains, the quaint villages, breathtaking landscapes, gorges , viaducts , towering rock walls, and evergreen manicured landscapes. We passed through so many incredible tunnels, and bridges that I lost count of it. And the most unforgettable one was when the train went into the world -famous Landwasser Viaduct. I took a video of it that I have watched it over and over again. It is a masterpiece of engineering , that made it possible for everyone to experience the natural beauty of the Alps in the comfort of your seats. We had a 15 minute coffee break in one of the most scenic spot in Alp Grum with the view of the beautiful town of Poschiavo . We had a coffee in the station cafe's outside veranda that juts out of the building high above the valley below with the view of the melting glacier , one of the tallest waterfalls I have ever seen where the melting glacier ice has created which looks like a natural green coloured swimming pool down bellow.What a view! We continued our journey where the train does a circular route it was mind bugling because we were looking on this side of the mountain one minute and the next thing we're on lthe otherside of the mountain , it's hard to explain , the line is famously called the circular viaduct of Brusio. We decided to get off at the small town of Poschiavo a typically Italian architecture buildings all around to have lunch . We lingered for a nice homemade Italian food and caught the train back where we had a 2 hour stop over at St. Moritz. Traveling into and right through the UNESCO World Heritage site is an experience that will stay with us for a very long time . Switzerland we Love you!
