Northern Mindanao / Lanao del Norte
Iligan
Iligan is a highly urbanized city at the mouth of Iligan Bay, known for Maria Cristina Falls, the Agus River hydropower complex, and a steel industry history that shaped the city’s economy for decades. The National Steel Corporation was once Asia’s largest steel mill at 1.2 million tons annual capacity by 1992. It closed in 2009 after a period under private ownership by Ispat Industries, leaving an estimated 14,000 workers directly unemployed and a 400-hectare industrial site still idle as of 2025. The closure cost the city an estimated 3 billion pesos in unpaid taxes and over 1.4 billion pesos in annual industry losses. The Agus-Pulangi Hydroelectric Complex, which includes seven plants with roughly 1,000 MW of installed capacity, is managed by PSALM. Only about 600 to 700 MW is typically operational due to aging equipment and water flow variability. In 2025 and 2026, Iligan City strongly opposed privatization proposals for the complex. Mindanao State University Iligan Institute of Technology was established in 1968 and enrolls between 10,000 and 14,999 students across 54 graduate programs and nine degree-granting colleges. The campus connects the city to engineering, science, and technology education in a way that has partially offset the industrial losses.

Frequently Asked Questions About Iligan City
What is Iligan City known for?
Iligan City is known as the City of Majestic Waterfalls, a title tied to Maria Cristina Falls and Tinago Falls. Maria Cristina Falls is a twin cascade on the Agus River, about 98 meters high, harnessed for hydroelectric generation and part of the Agus-Pulangi Complex with seven plants and about 1,000 MW of installed capacity. During dry season or high demand periods, water flow over the cascade is reduced for generation. Tinago Falls, meaning hidden in Cebuano, is a roughly 55-meter waterfall in Barangay Rogongon reached by a long staircase and a short boat ride across a gorge pool. The city is also known for its industrial history as the site of the National Steel Corporation, once Asia's largest steel mill at 1.2 million tons annual capacity. NSC closed in 2009 under Ispat Industries ownership, leaving a 400-hectare industrial site still idle and causing lasting economic damage to the city.
What region is Iligan City in?
Iligan City is a highly urbanized city in Lanao del Norte province, within Northern Mindanao (Region X). Despite being in Lanao del Norte, Iligan is governed as an independent HUC and is distinct from the province’s other municipalities. Its proximity to Marawi City (about 30 kilometers away) makes it a link point between Northern Mindanao and the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM).
How do you visit Maria Cristina Falls in Iligan?
Maria Cristina Falls is 9.3 kilometers southwest of Iligan City center, in Barangay Maria Cristina at the Agus 6 Hydroelectric Plant complex managed by PSALM. From the city center, take a jeepney toward Buru-an or Linamon and ask the driver to drop you at the Maria Cristina Falls corner. From there, hire a habal-habal to reach the falls viewing area. Entrance fees are ₱20 to ₱35 per person, with multicab tour rides available for ₱10. Because the falls are part of an active hydropower system, water flow over the cascade varies depending on season and electricity demand. During dry season or periods of high grid load, water may be diverted for generation and the falls run lower. Verify gate hours and current flow status before the trip.
What is Tinago Falls?
Tinago Falls, meaning hidden in Cebuano, sits in a deep canyon in Barangay Rogongon. It is approximately 55 meters high with typically emerald green water surrounded by steep gorge walls. To get there, take a jeepney from the Iligan city center toward Buru-un for ₱15 to ₱20, then hire a habal-habal for ₱50 to ₱80 to the falls entrance. There are two main approach routes: one through Buru-un and one through Linamon at Highland Resort road. Entrance is ₱25 per person, with a raft ride across the gorge pool for ₱10 per person plus a life vest fee. Budget around ₱200 to ₱300 total per person for transport and entry. Wear grip footwear and expect a steep descent and return climb.
What was the National Steel Corporation in Iligan?
The National Steel Corporation was a government-owned integrated steel mill built in Iligan City in the 1970s to use cheap hydroelectric power from the Agus River. At its peak in 1992, it had capacity of 1.2 million metric tons annually and was described as Asia’s largest steel mill of its type. Ispat Industries acquired the NSC in 2004. The plant closed in 2009, leaving an estimated 14,000 workers directly unemployed. The city estimates the closure cost over 1.4 billion pesos in annual industry losses and that more than 3 billion pesos in unpaid taxes and utility bills remained outstanding. The 400-hectare NSC site in Barangay Kiwalan remained idle as of 2025, and various proposals for redevelopment have not advanced into active construction. The industrial complex shaped Iligan’s urban geography, labor history, and fiscal capacity in ways that continue to matter today.
Is Iligan City safe to visit?
Iligan City itself is generally safe for domestic tourism by Philippine urban standards. The city is distinct from Marawi City, which is approximately 30 kilometers away and is still in post 2017 rehabilitation. Iligan hosted large numbers of Marawi evacuees during and after the 2017 siege, and the two cities are socially and economically interconnected. For waterfall visits, the main safety concerns are physical: the stairs at Tinago are steep, and access at Maria Cristina depends on gate rules. Monitor national travel advisories for Lanao del Norte during periods of elevated security alerts.
What is Diyandi Festival?
Diyandi Festival is the major annual cultural celebration of Iligan City, held in September. It honors the diverse communities that make up the city, including Christian settlers, Maranao neighbors, Cebuano migrants, and Indigenous groups, and commemorates the city’s founding. The festival includes street dancing, cultural performances, trade fairs, and civic events. The 2025 Diyandi featured more than 130 activities across 30 days. The name and celebration reflect Iligan’s position between Northern Mindanao’s Christian majority areas and the Muslim Lanao communities.
What is MSU-IIT and how does it shape Iligan City?
Mindanao State University Iligan Institute of Technology was established by Republic Act 5363 in 1968 and became MSU’s first autonomous unit in 1975. The campus is in the Iligan city center and enrolls between 10,000 and 14,999 students. It offers 54 graduate programs across nine degree-granting colleges and schools covering engineering, science, education, arts, and business. MSU-IIT is regarded as one of the leading engineering and science universities in Mindanao. The university draws students from Lanao del Norte, BARMM, and wider Mindanao, maintaining a student presence that partly offsets the economic impact of the National Steel Corporation closure.
How do you travel between Iligan and Marawi?
Iligan City and Marawi City are connected by a 30-kilometer national highway, with typical travel time of about 38 minutes by car, taxi, or van. Vans and other public transport operate between the cities depending on terminal schedules. The road was confirmed safe for regular travel in 2022. Marawi is the next major city on the road that continues into Lanao del Sur and BARMM territory. Iligan served as the main evacuation and relief staging point during the 2017 Marawi siege, and the two cities remain economically linked through trade, services, and family connections. Many families displaced from Marawi in 2017 settled in Iligan and continue to pay rent there while maintaining ties to Marawi.
What are the flood risks in Iligan City and what happened with Typhoon Sendong?
Iligan has three principal rivers draining into Iligan Bay: the Agus, the Mandulog, and the Iligan River. Typhoon Sendong in December 2011 caused catastrophic flash flooding that killed 490 people in Iligan, with water rising 7 to 10 meters in the main rivers within hours. Two national highway bridges were destroyed and 1.7 billion pesos in infrastructure damage was recorded. Upstream deforestation in the Mandulog watershed was cited as a contributing factor by post-disaster studies. The city has ongoing drainage and flood control projects, but the upstream land use issue means flood risk remains tied to logging and quarrying activity in the surrounding mountains.
