T’BOLI, South Cotabato — After a two-week closure due to security concerns, the scenic Lake Holon has officially reopened to the public. Mayor Keo Dayle Tuan lifted the closure order through Executive Order 31 on Monday, April 20, 2026, after security forces deemed the area safe for controlled public access.
The popular trekking destination was temporarily shuttered on April 9 following a military encounter between the Army’s 105th Infantry Battalion and alleged New People’s Army (NPA) rebels in nearby Sitio Tbul.
The decision to reopen follows extensive security assessments and clearing operations conducted by the T’boli municipal police and the military.
- The Incident: The April 9 clash resulted in the deaths of two high-ranking individuals, including Anthony Narvasa (alias “Magaw”), the secretary of the NPA’s Far South Mindanao Region.
- Current Status: Officials have confirmed that the trekking trails and the lake’s surrounding areas are now generally safe, though access remains “controlled” to ensure the continued safety of visitors and the local community.
Nestled within the crater of Mt. Melibengoy (also known as Mt. Parker), Lake Holon holds significant cultural and environmental value:
- Cultural Significance: To the T’boli tribe, Holon (meaning “deep water”) is considered a sacred place.
- Environmental Honors: The lake is part of the Allah Valley Protected Landscape. It was recognized in 2003 and 2004 as the cleanest inland body of water in the Philippines and was named among the world’s “Top 100 Sustainable Destinations” in 2016 and 2017.
- History: The mountain and lake were named after US military officers Frank Parker and Russell Maughan, who died in a 1930s plane crash while mapping the region. It is also remembered for a tragic crater wall collapse in 1995 that caused significant downstream flooding.
For those planning a visit, the local government reminds tourists of the following:
- Permits: Visitors are typically required to register and secure permits through the T’boli Tourism Office.
- Controlled Access: Due to the recent security scare, trekkers are encouraged to follow official trails and adhere to the guidance of local T’boli guides.
- Sustainability: As a protected landscape, strict “leave no trace” policies remain in effect to preserve the lake’s status as one of the country’s cleanest natural landmarks.
