The Mission Houses are located at 553 South King Street in downtown Honolulu. The houses are open Tuesday through Saturday only from 10 a.m. until 4 p.m., and closed on major holidays. Guided tours start on the hour between 11 a.m. and 3 p.m., and are the only way to gain access to the buildings’ interiors. It’s free to walk the grounds, but tours cost $10 for adults and $6 for children and college students with ID (there are discounts for military and Hawaii residents, also with ID). The excellent Mission Social Hall and Café, run by renowned Hawaii chef Mark “Gooch” Noguchi, is reason in and of itself to visit. It serves authentic and modern Hawaiian fare for lunch only—it’s open the same days as the Mission Houses and closes by 2 p.m.
