After hiking all day, no one wants to think about nightlife activities. Its cook, eat and clean up. It gets quite cold too, especially if the winds start blowing. So its bundle up and go to sleep listening to the pitter patter of mice footsteps outside your tent.
The greatest thing about evenings when camping is seeing all the stars. Once the sun sets fully far from the city lights, the sky is an explosion of constellations. Its a great time for star gazing, if you're not too tired.
I think I saw a local bar there, but if you are with friends you could always just amuse yourselves in your room (if you have one) and get up early to get out into nature with the early morning sun.
Dress Code: anything
