For hiking trails in Hawaii, look to Lanikai for one of the Oahu hikes! For day activities and things to do away from Waikiki and Honolulu during your Hawaii vacation, drive a rental car or take the bus to Kailua. The pillbox hike trail summit has ocean views of Kailua Bay, Mokulua Islands, and Oahu beaches. Put hiking gear on the Hawaii packing list to have an outfit for hiking when you travel to Hawaii! After the hike, go snorkeling at nearby Lanikai Beach, one of the best beaches on Oahu!
