Question: How do people protect themselves from the legendary ghost warriors that inhabit the Manoa Falls Trail?
Context: Manoa Falls is a waterfall located in the Manoa Valley in Honolulu, Hawaii.  It is located in the Manoa Falls Trail which is a 1.6 mile trail in on the Island of Oahu.  The trail leads up to the 150 foot waterfall.  Swimming in the pool below the waterfall is highly discouraged because there is a threat of becoming infected with Leptospirosis.  This disease causes mild to moderate flu-like symptoms that can last for up to 1 to 2 weeks.  Many tourists are attracted to the waterfall and the scenery throughout the Manoa falls trail leading up to it.  Another attraction near Manoa Falls is the Lyon Arboretum.  The Lyon Arboretum preserves many endangered Hawaiian plant species.  The hike to Manoa Falls and back is around a one hour round trip.  The waterfall and surrounding area experiences rainfall almost everyday, and flash floods are also possible. Panther Falls is the first of two waterfalls on the Angel Falls Trail in Rabun County, Georgia.  The second waterfall on the trail is Angel Falls.  The falls are each about 50' in height on Joe Branch Creek.  The trail begins at the Rabun Beach Camping Area #2 and is a moderately strenuous 0.5 mile hike to Panther Falls with Angel Falls and additional 0.5 mile. In Hawaiian legend, Nightmarchers ("huaka'i pō" or "Spirit Ranks," " 'oi'o") are the ghosts of ancient Hawaiian warriors.  On the nights of Kane, Ku, Lono, or on the nights of Kanaloa they are said to come forth from their burial sites to march out to past battles or to other sacred places.  They march at sunset and just before the sun rises.  Anyone living near their path may hear chanting and marching, and must go inside to avoid notice.  They might appear during the day if coming to escort a dying relative to the spirit world.  Anyone looking upon or seen by the marchers will die unless a relative is within the marchers' ranks- some people maintain that if you lie face down on the ground they will not see you.  This is to show respect.  However, if exiting the area is the fastest option, it is recommended.  Placing leaves of the ti ("Cordyline" sp.)  around one's home is said to keep away all evil spirits, and will cause the huaka'i pō to avoid the area.  Another thing is to always highly respect the night marchers which can result in great things. Silver Cascade Falls is a waterfall located on St. Mary's Creek in the North Cheyenne Cañon Park of Colorado Springs, Colorado.  Silver Cascade can be reached by hiking a short but steep trail up from North Cheyenne Canyon road at the Helen Hunt Falls trail head.  The trail is less than half a mile, but steep in places and the footing can be slippery, especially when wet or when frozen over during the winter months.  Care should be taken especially at the top of the falls, as the granite face of the falls is polished, slippery, and much steeper than it appears.  The falls have an interesting spout feature about 50 feet below the crest due to an upturn in the rock face.  During high flow times, the spout can shoot water over 10 feet off the rock face.  The water running over Silver Cascade originates in Buffalo Canyon, passing over St. Mary's Falls and Silver Cascade Falls before merging with North Cheyenne Creek down stream of Helen Hunt Falls. Panther Creek Falls Trail is an interior hiking trail in Georgia's Cohutta Mountains, in Fannin County, northwest of Ellijay, at the southern end of the Smoky Mountains.  The trail falls within the 35,000-acre Cohutta Wilderness, part of the Wilderness's 87 mile (140 km) trail system.  As an interior trail, Panther Creek Falls cannot be accessed by road, but only via other hiking trails.  Eastern access is via the East Cowpen Trail, and its western access via the Conasauga River Trail.  The trail starts at the confluence of Panther Creek and the Conasauga River. There are 24 named waterfalls in Ricketts Glen State Park in the U.S. state of Pennsylvania along Kitchen Creek as it flows in three steep, narrow valleys, or glens.  They range in height from 9 feet (2.7 m) to the 94-foot (29 m) Ganoga Falls.  Ricketts Glen State Park is named for R. Bruce Ricketts, a colonel in the American Civil War who owned over 80,000 acres (32,000 ha) in the area in the late 19th and early 20th centuries, but spared the old-growth forests in the glens from clearcutting.  The park, which opened in 1944, is administered by the Bureau of State Parks of the Pennsylvania Department of Conservation and Natural Resources (DCNR).  Nearly all of the waterfalls are visible from the Falls Trail, which Ricketts had built from 1889 to 1893 and which the state park rebuilt in the 1940s and late 1990s.  The Falls Trail has been called "the most magnificent hike in the state" and one of "the top hikes in the East". Mānoa Falls Trail is a 1.6 mile trail on the island of Oahu in Hawaii.  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. Gywnns Falls Trail is a 15 mi series of hiking and bicycling trails inside Baltimore, Maryland, named for the Gwynns Falls, whose course it follows, and the surrounding Gwynns Falls Leakin Park it passes through.
