This little-known estate and grounds are landscaped like a French palace. Called The Garden of the Bishop's Close, it was given to the Episcopal Diocese of Portland by the Kerr family in 1957. Different plant varieties are labeled, making it an educational tour of Northwest plant life. No matter what the season, this is always a great place to visit. A winding, somewhat hilly pathway can get steep, so you may want to stick to the flatland. No bicycles, picnics, food or drinks are allowed, but admission is free.
