Round Top Drive is a scenic nine mile loop around the Tantalus mountains, just 30 minutes from the Ko Olina Beach Villas. Spectacular itself, the drive includes offshoots to many top visitor attractions, including Puu Ualakaa State Park and the Pacific National Cemetery.
Furthermore, there are several scenic overlooks that afford excellent views of colorful sunsets, Oahu’s coastline, or the Tantalus mountain range. Additional lookout points open views of Diamond Head or Waikiki itself, with unprecedented visibility for Oahu. The drive is a memorable experience in and of itself and can be done by car, bike, or even foot.
