Hallstatt salt mine tour

You don't have to wear anything special for the tour. They provide overalls/jackets for everyone to wear. You can check it out on Google images.

That's right. You will be given a jumpsuit to wear, hardhat/helmet, too IIRC. Just wear whatever you would wear on the way there.

Just watch out for The World's Most Painful Splinter as you go sliding down that wooden beam! ;)

Thanks for the quick replies, suggestions, and sense of humor. Very helpful!

Wear comfortable shoes as it is a lot of walking and standing.

You will adore this. I wouldn't wear flip flops. Wear sensible shoes. Otherwise, you'll be all set. Enjoy!!

there is a reasonable up hill walk from the top of the funicular ( the walk is uncovered- in case its raining etc) to where you get the overalls, so good shoes ( and some degree of fitness) are a must. the slides were great.
hope this helps.
