One of the things I loved the most about Round Hill was the enormous vegetable garden on the property. The garden is located at the top of the hill, a quick walk in the cool mornings-a longer walk during the heat of the day!
While the house (actually a compound of several houses from around Thailand and rebuilt on site) was interesting, to me, the most outstanding features of the museum were the garden rooms you pass through between the buildings. There were water gardens, tropical flowers, and gorgeously composed niches throughout the complex.
When you visit the museum, you must take a guided tour. The tour was not long, but informative and a worthwhile addition to your itinerary.
