Hiking to the top of Diamond Head State Monument is a must-do activity for any visitor to Honolulu.
Visitors can take guided tours of the palace, which offer insights into the lives of Hawaii's monarchs and the palace's historical significance.
For a more interactive experience, you can sign up for a behind-the-scenes tour or a "zoo camp" program for kids.
If you're more experienced, head to the North Shore, where the waves are bigger and more challenging.
