Visit the only royal palace on American soil — and the sad site where Queen Lili’uokalani, the last Hawaiian monarch, was imprisoned as her reign came to an end. The palace was built in 1882, complete with modern conveniences like electricity and telephone lines. Don’t miss the King and Queen’s thrones, ornate bedrooms, and royal jewelry. Both the King and Queen were gifted musicians, and the Queen’s most famous manuscript, Aloha Oe (which translates to “a fond farewell, until we meet again”), written in her own handwriting, lives on in the Iolani Palace. Both guided and self-guided tours are available, and reservations are required.

Open: Tuesday through Saturday 9 a.m. to 2 p.m. Guided tours take place every 15 minutes from 9 a.m. through 11:15 a.m.; self-guided audio tours take place from 11:45 a.m. through 3:30 p.m. Guided tours cost $12 per person.
