4.5Ko Olina Lagoons(1.773 reviews) - Scenic and Enjoyable Spent More than 3 hours Bodies of Water
Travelers flock to these artificial lagoons along the western coast of Oahu to swim, snorkel, and paddleboard in the calm, crystal clear, turquoise waters and bask in the Hawaiian sun. Book a boat tour of the lagoons to learn more about the area's history and marine life, and take in the beautiful Hawaiian sunset with a stroll along the beach. The lagoons are a 30-minute drive from the city—arrive early to secure a parking spot or get a shuttle bus in. Stay at one of the seaside resorts to make the most of it, and visit during the warmer months from April to October. – TripadvisorSee more..
4.5Waimea Bay(1.287 reviews) - Beach is Great...Finding Parking is Not Bodies of Water
Waimea Bay is the deepest bay on Oahu’s North Shore and the birthplace of big-wave surfing, especially in winter. Between November to February, waves reach up to 40 feet in height, challenging even the most expert surfers. Even if you're not a fan of riding the waves, watching these pro surfers in action will get your heart racing too. Otherwise, visit during summer for the soft sand, arresting seaside views, and calmer waters—perfect for swimming, snorkeling, diving and even cliff-jumping. The wave conditions here fluctuate quickly, so look out for the colored flags before diving in. – TripadvisorSee more..
