First of all, you should know that there is no entrance to the house or palace. You pay for access to some small interesting beautiful gardens and money to go down to a mine. I'm not kidding. You go down a few hundred steps from the top of the canyon to the bottom of the water. Walking at different heights, and wet and slow corners. The climb up will definitely get you exercise. So if you are physically injured, uncomfortable, wearing inappropriate shoes, or any excuse you can have, don't try. I recommend the cafe that exits. Just outside the attraction, go there, wait for your friends to come back.
