The trail is a part of the Honolulu Makau Trail System, and leads to a popular 150 foot waterfall called Manoa Falls.  Hiking the trail is approximately a one-hour round trip.  Many tourists are attracted to the waterfall and scenery throughout the trail.  The trails have a history as one of the earlier Hawaiian trails.  There are many legends of the Night Marchers, or ancient Hawaiian warriors associated with Manoa Falls.  Scenes in movies such as Jurassic Park and Catching Fire were filmed at Manoa Falls.  The Manoa Falls trail harbors many native Hawaiian plant species and tropical birds as well.  The Lyon Arboretum, located in the Manoa Valley at the base of the trail is another popular tourist attraction and aims to preserve endangered Hawaiian plants.  Rain showers are very common in on the trail and the path to the waterfall is often muddy and slippery.  Flash floods may also occur at any time.  Swimming in the pools of water on the trail is highly discouraged due to the threat of Leptospirosis.

The Lenape Trail is a trail connecting Newark, New Jersey with Roseland, New Jersey.  It was established in 1982.  It is the fifth longest trail in the state behind the Delaware and Raritan Canal Trail, the Appalachian Trail, the completed section of the Highlands Trail in the state and the Batona Trail.  The Lenape trail traverses Newark and its suburbs, as well as the Watchung Mountains and Passaic Meadows.  Because of the steepness of the Watchung Mountains and the flood-prone nature of the Passaic Meadows, the former basin of Glacial Lake Passaic, these areas have remained much less developed than the rest of the northeastern part of the state.  This trail therefore offers hikers an opportunity to see cultural and historical sites of an urban trail, as well as large natural and undeveloped areas.  The trail's proximity to New York City and the various ridges it traverses, including Forest Hill, Orange Mountain (part of First Watchung Mountain), and Second Watchung Mountain, offer many views of the skyline.  The Lenape Trail forms a segment of the Liberty-Water Gap Trail and incorporates the West Essex Trail, the Lenape Trail's only rail-to-trail section.  The Lenape Trail also connects with Morris County's Patriots Path trail system on its western terminus.

Its eastern endpoint is in Jockey's Ridge State Park on the tallest sand dune on the east coast.  The trail is envisioned as a scenic backbone of an interconnected trail system spanning the state.  As such, the trail's route attempts to connect as many trail systems and natural scenic areas as practicable.  A little over half of the trail is complete in multiple, disconnected segments across the state.
