What are the most popular hiking tours in Oahu?

Diamond Head crater hike

Most sightseeing tours in Oahu include the famous hiking trail that leads to the Diamond Head. This volcanic cone was formed between 400,000 and 500,000 years ago, and is shaped like the dorsal fin of a tuna. As you hike up towards the crater, you'll experience panoramic views of Waikiki and the surrounding area.

Heading around the island, you’ll stop at Halona Blowhole, where water shoots out of the geyser at heights of up to 9 meters. Moving on, you’ll visit a macadamia nut farm, where you can sample its locally-grown produce. After relaxing in Haleiwa Beach Park, you’ll stop by the Dole Plantation for a pineapple treat.

Makapu’u Lighthouse or Koko Head sunrise hike

Heading to the east of Oahu just in time for sunrise, you can choose to hike either the Makapu’u Lighthouse trail or the challenging Koko Head Crater trail. The hike you pick will depend on your preferences and your fitness level.

If you’re an avid hiker, you may choose to trek up the Koko Crater trail, which consists of more than 1,000 stairs over a 1.5-kilometer summit.
