Koko Crater

Koko Crater is a volcanic cone in Hawaii Kai.  This is a great hike for those who are interested in getting a good cardio workout.  The trail basically goes up the side of the volcanic cone while getting steeper as you get closer to the top.  The trail consists of crumbly rock and railroad ties.  The trail follows an old railway path and the tracks with ties are still there.  The railroad ties are like steps making it a stair climber exercise with a view.  Remember to bring some water with you.
