Pūpūkea is a popular area on O'ahu's North Shore for living and for visiting. The best known surfing sites of Velzyland, Sunset (at Sunset Beach Park), Kammieland, Pupukea, Ehukai, Pipeline (these latter two off adjacent Ehukai Beach Park and Banzai Beach) and lesser breaks are arrayed off this shore. Popular diving areas known as Three Tables and Sharks Cove are located at Pupukea Beach Park. And, at the southwest end of Pūpūkea is Waimea Bay, with one of the most popular beaches on the island forming the shore at Waimea Beach Park.
Popular residential areas here include the beach lots at Sunset Beach and the uplands of Pūpūkea. The only drawback to living in this part of the island is the considerable driving distance to Honolulu.
