What an experience
We decided to do this trip just today. We didn't really think about doing it, but how glad am I that we did. It was fantastic. From beginning to end, it was amazing. You first of all have to get to the base camp (as such) which you do by travelling in the funicular which is like a cable car which goes up the side of the mountain. It only takes about 2 minutes. You then have to walk about 350m to get to the start of the mine. We had a fantastic guide with us today, and I was very impressed by her German English and French (even though she said she can't speak French). The whole trip takes approximately 3 hours, and the visual displays inside are amazing. It's hard to believe you are actually about 350m into a mountain and about 85m underground. It was such a great experience. If you have the pleasure of staying in beautiful Hallstatt, you should really do this tour. It is the oldest mine in the world seemingly. The trip costs €80 for 2 of us. It is an experience I will never forget.
