Filoli Gardens, located about 30 miles south of San Francisco in Woodside, California, covers 654 acres. It is the site of a 36,000 square foot Georgian house and a 16 acre English Renaissance garden, which is a series of enclosed spaces within brick walls. Visitors will see well-manicured gardens with clipped hedges and classic reflecting pools. Other gardens include a Bonsai collection, magnolias, an olive orchard, and a rose garden.
A little history of the gardens: Filoli was built between 1915 and 1917 for William Bowers Bourne II, owner of a very successful gold mine and President of Spring Valley Water Company. Following Bourne's death, the estate was sold to William Roth, who in 1975 donated it to the National Trust for Historic Presevation.
Filoli has served as the set for many Hollywood films. You may have seen the mansion on the opening credits for the show, Dynasty.
There are several tours you can take, including one of the mansion. If you can,I would recommend doing it. You can also take a 2-hour nature hike. A word of caution about that - some parts are strenuous, so you should be in good health to do it.
The gardens are open Tuesday through Saturday from 10:00 AM to 3:30 PM. Admission is $15.00 for adults and $5.00 for children.
