Alsgruvan is a small mine 1 hour from central Stockholm. It’s basically a tunnel going straight into a hill and is allegedly 100m long. It was really cool and definitely worth a visit but most people (including me) take pictures in a way that makes it look waaaaay bigger than it actually is. I went there during a rainy autumn and a normal pair of rubber boots were still enough.
