Sintra, Portugal
The Quinta da Regaleira is so unusual that it's difficult to put into words. You'd have to experience it for yourself. Caves, waterfalls and staircases. A green house, a chapel and an unfinished well 27m deep that leads out of a cave with a winding staircase to the top of it. All found in the garden of a wealthy scientist and book collector. A memorable experience that we'd like to repeat with Jenna and Jason.
