🏖️ Beaches & Water Activities
1. Snorkel at Hanauma Bay

2. Learn to Surf in Waikiki
Waikiki's gentle waves have been teaching beginners to surf for over a century. The long, rolling breaks are perfect for first-timers, and local instructors can have you standing on your first lesson. Most surf schools offer 2-hour group lessons that include board and rash guard.
3. Watch Sunset at Waikiki Beach
There's a reason Waikiki is world-famous. The combination of Diamond Head's silhouette, swaying palms, and golden sunsets creates postcard-perfect moments every evening. Grab a spot near the Duke Kahanamoku statue for the classic view.
Sunset Splash Adventure
Pink Sails Waikiki runs a 2-hour sunset catamaran with swimming and snorkeling included. You swim from the boat as the sun goes down. Informal, fun atmosphere. Free cancellation. One of the best value sunset options on Oahu—same boat, half the price of some competitors.

A visit to the USS Arizona Memorial is a moving and essential Oahu experience. The site commemorates the 1,177 sailors who lost their lives on December 7, 1941. Free tickets are available, but we recommend booking a guided tour that includes the USS Missouri battleship.
Pearl Harbor City – from Waikiki
E Noa Corporation runs a 5-hour bus tour from Waikiki covering Pearl Harbor and downtown Honolulu sites including the USS Arizona Memorial Visitor Center, King Kamehameha Statue, and Aloha Tower.
