Includes 12 trailed peaks on the Hawaiian island of O'ahu. All 12 are exciting climbs, accessible, and have trails leading to the top. 9 of the peaks lie in the Ko'olau Mountains and 3 in the Waiana'e Mountains. The peaks vary from easier hikes to more challenging climbs; it's hard to tell which peak is the hardest to climb since all have a different character and pose different challenges.

  • As always, on Hawaii trails always expect humidity, rain, mud, and never forget about the strong heat of the sun.
  • The two big boys, the Ko'olau tallest Konahuanui, and Oahu's tallest Mt Ka'ala, will test your cardio, scrambling skills, and "mud resistance".
  • Work your way up from easier hikes like Pu'u O Hulu and Tantalus Peak to harder, more advanced hikes like Pu'o'hule'hule which includes a longer jungle walk, or Ahiki which requires more climbing/scrambling skills.
  • Climbing these mountain peaks will introduce you to real Hawaii hiking. From beautiful jungle walks to exposed ridges, from amazing ocean and mountain views to bird's eye views of Honolulu, you will have it all!
