This easy .75-mile (one-way) hike is terrific for families; it takes less than an hour to reach idyllic Manoa Falls. The trail head, marked by a footbridge, is at the end of Manoa Road, past Lyon Arboretum. The staff at the arboretum prefers that hikers not park in their lot, so the best place to park is in the residential area below Paradise Park; you can also get to the arboretum via TheBus no. 5. The often-muddy trail follows Waihi Stream and meanders through the forest reserve past guavas, mountain apples, and wild ginger. The forest is moist and humid and inhabited by giant bloodthirsty mosquitoes, so bring repellent. If it has rained recently, stay on the trail and step carefully because it can be very slippery (and it’s a long way down if you slide off the side).
