 Under part of the town centre are the Dorking Caves which were dug for sand, mostly in the 19th century, and are open occasionally to the public.Each year in April, the town plays host to the Leith Hill Musical Festival for local choral societies.This was founded in 1905 by Margaret Vaughan Williams, sister of the composer Ralph Vaughan Williams, and Lady (Evangeline) Farrer, wife of Lord Farrer of Abinger Hall.
