Hakone Detached Palace ({, Kyū Hakone Rikyū) used to serve as a summer palace for the Imperial Family, but was later opened to the public. It is located at the southern shores of Lake Ashinoko on the peninsula between Moto-Hakone and Hakone-machi.

Only a relatively small and simple building remains of the former palace complex. It is surrounded by a beautiful park, known as Onshi Hakone Park, which offers nice walking trails and scenic views of Lake Ashinoko and Mount Fuji, if visibility permits. Visibility tends to be better during the colder seasons of the year than in summer, and in the early morning and late evening hours.
