Manoa Falls

Mānoa Falls is a 150-foot waterfall along the Manoa Falls Trail in Honolulu, Hawaii. Swimming in the pool below the waterfall is highly discouraged because there is a threat of becoming infected with Leptospirosis, a disease causing mild to moderate flulike symptoms that can last for 1 to 2 weeks. Many tourists are attracted to the waterfall and the scenery throughout the trail leading to it. Another attraction near Mānoa Falls is the Lyon Arboretum, which preserves many endangered Hawaiian plant species. The hike to the waterfall and back takes about one hour. The waterfall and surrounding area experience rainfall almost every day, and flash floods can occur.

Characteristics
Mānoa Falls is located on the island of Oahu in Honolulu, Hawaii, in Manoa Valley, and comprise a 150 foot waterfall that empties into a small pool of water. The waterfall is nestled in the mountains of Koolau in a tropical rainforest. Since the area surrounding the waterfall is considered a tropical rainforest, it is prone to heavy rainfall often making the ground damp and muddy The high amount of precipitation leads to a high amount of plant life near the falls. There is often less water in the waterfall during the summer months, which leaves peak tourism extending from summer to fall, before the rainy months of November–March.

Leptospirosis
Swimming in the pool at the bottom of the falls is discouraged. This is due both to occasional rockfalls and to the bacterial disease leptospirosis, which causes severe flu-like symptoms. Leptospirosis is found in freshwater and is common in tropical climates. In Hawaii, rats and mice often carry the disease and can easily transfer it to humans through their urine.

Ecology
The Lyon Arboretum is located at the entrance to the Mānoa Falls Trail in Mānoa Valley. It contains over 5000 plant species. Some plant species included are heliconias, gingers, aroids, bromeliads, and some native Hawaiian plants. Many tourists visit the arboretum but some also go for research and academic purposes. It provides several different programs that develop innovations to restore endangered native Hawaiian plants.
