How charming is the town that fascinated Goethe? Goethe once wrote here: I left my heart in Heidelberg. I came here specially to this small town where Goethe "lost his soul" and felt that the trip was worthwhile. 1. Philosopher's Trail: It carries the thinking and inspiration of countless philosophers and poets. Goethe, Hegel, and Heine all walked here. The whole journey is about 2 kilometers, with beautiful scenery along the way. 2. Heidelberg Castle: This castle stands on the top of a hill and is one of the oldest and most famous castles in Germany. What I love most is standing on the castle terrace at sunset, overlooking the Neckar Valley and the old town for a limited time. 3. Old Bridge: The two ends of the bridge lead to the castle and the Philosopher's Trail respectively. Standing on the bridge and taking a photo will create a postcard. Remember to touch the monkey statue at the end of the bridge, which is said to bring good luck. 4. University Square and Library: One of the oldest universities in Germany, scholars such as Hermann Hesse and Hegel once studied here. The student prison at the school is very historic. 5. Old Town: Cafes, shops, and galleries can be found everywhere in the Old Town. With cobblestone pavements and brightly colored houses, you can feel the leisureliness of this city by stopping for a cup of coffee. 6. Best time to travel: Summer and autumn, especially October-November, the colorful autumn leaves add a lot of romance to the city. 7.
