To get to this hike drive to the top of St.Louis Heights and park in the Wa'ahila state park at the top. Park hours are 7am-745pm. The hike starts off pretty simple on a wide path the just keeps going up. You soon get to a junction where you go left and from then on the hike starts going up and down over the ridges. There are some rocky sections that involve small amounts of climbing up and down but other then that the hike is pretty easy. I'd recommend this to the beginner hikers as well as the more experienced. Once toward the top you get great views of Manoa Valley and Palolo Valley. At the end of the trail you meet the kolowalu trail which is a steeper hike that will take you down into the back of Manoa Valley. There is also a trail past the end of trail sign. This goes to the top of Mt.Olympus and should not be attempted by novice hikers. Hike this section at your own risk as you are not suppose to go past the end of trail sign but people do anyways. If you do choose to go past it be aware the trail gets a lot skinnier and has numerous rope sections that you will have to climb to reach the summit.
Water is a must especially on a hot day, Gloves may help with the rock section but it is definitely doable without them. There is a bee hive in a big tree that sits pretty much in the middle of the trail at one section so if your allergic be careful of this.
If you continue to My.Olympus you may want the gloves for all the rope.
