Water Adventures

Paddleboarding Oahu
For an immersive Hawaiian adventure on Oahu’s west coast, glide along the tranquil waters of Ko Olina on a paddleboarding excursion. Soak in the breathtaking views from a unique vantage point in the water, away from the hustle and bustle of the more crowded tourist spots.
Experience Ka’aumoana, an exclusive ocean activities program with sailing, paddling and snorkelling excursions centered on the Hawaiian wa’a experience. Under the direction of #FSWayfinder Nakoaokalani Prejean, experienced watermen and women guide Four Seasons guests in a multitude of safe, open ocean experiences for all ages, departing directly from Four Seasons' beautiful white sand beach cove.
Surf Makaha Beach
For an authentic Hawaiian experience, snag a surfing lesson from a local at Makaha Beach Park, the birthplace of surfing. Located on Oahu’s western coast, Makaha Beach lacks the crowds of more tourist-driven Waikiki Beach and North Shore beaches, but the swells are just as impressive.
Deep-Sea Fishing
With the Ko Olina Marina located next to the Resort, it’s easy to book a full- or half-day, deep-sea fishing adventure. Yellowfin tuna, Pacific blue marlin and mahimahi are popular catches. Let our chefs take your catch and prepare it for a perfect dinner for you and your family.
