It's a good two and a half hour drive from the city, and unfortunately we didn't have time to take the tour of the inside of the house. There was a man on the tour quoting the bible loudly anyways, so it seemed like an OK thing to miss out on for the time being.
I certainly plan to return and see the inside, though, because the exterior is stunningly beautiful. The brickwork and details are exquisite and the exotic architecture makes Olana feel magical.
The grounds, which were once a working farm, are massive and beautiful. A perfect spot for a stroll with the dramatic Hudson River as a back drop.
