The first picture above is the drive leading to the picnic area. Second is the entrance to the 'Aiea Loop Trail. Make sure to lock your vehicle up and conceal personal belongings as there were many signs warning of car break ins.
As you go further down the trail it becomes engulfed by the forest and I almost began to feel like I was back in the Pacific Northwest instead of Hawaii. If your family enjoys the outdoors, this hike is a must.
