The Limunsudan Falls is a two-tier waterfall located in Barangay Rogongon in the City of Iligan in the province of Lanao del Norte on Mindanao Island in Philippines. Lying almost on the eastern boundaries of Iligan, the water fall is at a distance of about 55 kilometers from the city, and listed as one of the twenty waterfalls within the area of jurisdiction of the city.
With a total vertical drop of about 870 feet from the top, it is the tallest waterfall in the Philippines. Its lower cascading alone is taller than the more famous and the most visited Maria Cristina Falls (with a plunge of only 320 feet) in Iligan.
Though Iligan, often referred to as the City of Waterfalls, has twenty waterfalls, perhaps the only city in the world that has so many waterfalls within its jurisdictional limits, only six of them are easily accessible. The Limunsudan Falls is also not easily accessible by vehicles, and it is mostly visited by tourists who are interested in trekking, which may take up to two days.
The absence of good motorable roads are limiting the accessibility to these scenic waterfalls and lush green landscapes of the tropical evergreen forests that grow on the steep slopes and valleys of hills and mountain ranges of volcanic origins. Some of these areas are accessible only by Habal-Habal (or the Skylab as the local people call it), a modified form of motorcycle that sometimes carry up to a dozen people and their baggage. These are specially designed to carry travelers in areas where jeepneys and tricycles cannot negotiate the narrow roads on the steep and rough terrains.
Some of the other notable falls in Iligan include the Mimbalut Falls, the Tinago Falls, the Bridal Veil Falls, and the Dodiongan Falls.
