Technically the Huntington Library and Gardens are in San Marino, not Pasadena. But Pasadena residents claim this wonder as their own. This romantic date will involve some walking. The gardens feature a wonderful desert garden, but somehow it is not romantic. However, the Rose Gardens and the Japanese gardens are very romantic and a couple can sit on a rustic bench in quiet and seclusion. When they get hungry, they can go to the Huntington Gardens Tearoom, which overlooks 3 acres of rose gardens.
