although it's 20 clams, it's a nice place,and plan 4-6 hours easy to see everything.
if you go to the Getty go here the next day.

The Huntington provides a perfect setting for the extensive art an historical collections. The botanical gardens are truly amazing, and are as beautiful as the art available to view. Great for families, and the staff was very gracious and accommodating.

This is worthy of an all-day visit. The collection of Art and old books is fabulous! But to me, the gardens are the high point of Huntington. I think its the largest, most comprehensive botanical I've ever visited. The gardens are in themes: Japanese, Camellia, Rose, Shakespeare, Herb, Tropical, and so forth. Ponds brimming with beautiful Koi, arched bridges, shade & sun, desert or jungle plants, its all here!! I liked especially the Sculpture Garden with its life size statuary of god, warriors, mythical beasts. I go to Huntington at least once a year, there is always something new.

One day is not enough. Whether you have any botanical background or not, it is an amazing place. During the week it is only open from noon until 4:30, but on the weekends it is open from 10am to 4:30. Different times of the year bring different exciting exhibits. The volunteers are helpful and will answer any questions you have. I just can't speak high enough of Huntington's!
