Descanso Gardens just released the dates for this seasons specific dates for when tickets go on sale, with members of the garden getting a two week head start on the general public.
I do not have all the details but here is the information that I do have on this beautiful garden.
Enchanted: Forest of Light will run from November 19 through January 7. Tickets go on sale to Descanso Gardens members on October 2 at noon, with tickets for the general public available on October 16 at noon. Timed tickets are required (and must be purchased in advance).
I do not have the details for prices yet but last year the cost was $28 for adults, $24 for seniors and children 3-17, and free for kids two and under.
