- 1) Koko Head Trail
Pick a cooler day to conquer Koko Head - the eastern peninsula along Maunalua Bay. Hovering over Hawaii Kai, this 1k hike takes you from Koko Head District Park to Koko Crater and up more than 1,200 feet. If you're not afraid of heights, the view at the top offers awe-inspiring 360 panoramic views of East Oahu and the Pacific Ocean. Working up a sweat has never looked so good.
Better than a stair-master, Koko Head takes visitors step by step up more than 1,050 stairs (so if you have a problem taking the stairs when the elevator isn't working, this may not be the hike for you). The stairway of railroad ties is visible from the road and dates back to World War II when railroad tracks were installed along the side of the mountain to carry soldiers to their bunkers on the summit.
Don't forget to bring lots of water and a camera so you have something - other than super sore legs - to remember the day by.
