The best weekend trips are those where this is the first and most important thing you pack. Bible, journal and books! (It was almost the only thing I packed. I had a razor and toothbrush and the workout clothes that were easy to reach; no clothes, no pajamas, no makeup.)
The second key ingredient is breathtaking nature.
The third, and most important, is amazing company (including if you get to travel alone and then that company is the Lover of your Soul)
