If you both are adventure seekers and want to skip hotel stays, then maybe climb a fort together. Korigad is a beautiful hill fort, located only 20 kilometres away from Lonavala near Aamby Valley. You can visit the fort at any time of the year for one-day treks.
What Makes It Awesome: The journey and the trek are de-stressing, and the view on your way and at the end of the trek is breathtaking. You've got to do this at least once, if you haven't already!
Difficulty Level: Easy to Medium
