Star gazing.
Alpnhaus is in a dark sky with no light pollution. If the night sky is clear, the Milky Way is on view. It can blow your mind! The millions of stars that you can see here is unbelievable.
If you’re interested in more, you can book at Kielder Observatory which is about a 20 minute drive away.
There is a great tool here so you can check your dates for dark sky-ness
