Cool place. Great docents. Interesting history. They ask for reservations for entrance, but if you just show up at the tour times (10:30 and noon), you will likely have no trouble getting in. The tours are leisurely, but well conducted. Tidbit: the property next door was owned by the wife of Gilbert Grosvenor, the founder of National Geographic. Pair this tour with a trip to the Fairchild Gardens for a plant lovers nirvana.
