O‘ahu’s fabled North Shore, home to epic winter waves, hosts Vans Triple Crown of Surfing (triplecrownofsurfing.com), the sport’s ultimate competition, every November and December. This dramatic coastline is also renowned for breathtaking mountains, forests, and valleys. North Shore Eco Tours (northshoreecotours.com) offers small group, land-based adventures that interpret the natural environment through the lens of Hawaiian cultural perspectives, values, and practices. The company has two hiking adventures, Huaka‘i Nui (Big Adventure) and Huaka‘i Iki (Little Adventure), and an ATV off-road expedition, Pua‘a Māiki (The Piglet), all on private lands. The adventures showcase O‘ahu’s incredible terrain and vistas, rare native plants and Hawaiian plants, and quiet freshwater pools as the guide shares the history, language, and stories of Hawai‘i’s natural environment.
For a bird’s eye view of O‘ahu’s natural landscape, head to Kualoa (kualoa.com), a 4,000-acre ranch on the island’s northeast coast spanning mountains, valleys, and the shoreline. The new Treetop Canopy Zipline Tour soars over gorgeous Ka‘a‘awa Valley and includes seven exciting tandem sections, two suspension bridges, and three min-hiking nature trails.
