Sunday it's closed, recommended to have a audio tour before 12PM and allow atleast one hour explore ground and first floor.. You also have basement showing collections of jewelry and swords (15min)
This was my first-ever audio tour (I always thought people looked silly with them). But it was great. Listening to the narration and sounds of the period really enhanced the visit!
Serves as a cultural repository for some of the most beautiful and striking objects in Hawaiian history (including a donated 13.88-carat diamond ring that once twinkled from King Kalakaua's pinky).
If you want to learn more about Hawaii's rich history, this is the place to go. I recommend the guided tour as they're very knowledgeable and in-depth. Take time to also walk the beautiful grounds.
Take the self-guided audio tour. Depending on how interested in history you budget 30-90 mins inside. Chock full of Hawaiian history (1778-1893) then leading to US territory/statehood!
