Dexter PrieteWhen tracking the thermal features of Davao de Oro, your mind likely drifts toward the heavily commercialized, steaming pools of mainstream ecotourism. But if you venture deep into the agricultural heart of Maragusan, specifically within the hidden corridors of Purok Mainit, you will find an unmapped, raw thermal anomaly that defies conventional tourism logic: Bukal sa Kanal Natural Hot Springs.
Let’s be completely transparent from the start: this is not a scenic mountain resort, nor is it a pristine jungle sanctuary. It is a highly secluded, raw volcanic vein hidden entirely within the deep maze of a commercial banana plantation. There are no manicured pathways, no entrance fees, and no structural comforts. However, for backcountry trackers interested in unique local folklore and raw geothermal anomalies, this spot offers a compelling look at the region’s active subterranean environment.

🚗 Navigating the Plantation Maze & Access Points
Reaching Bukal sa Kanal requires careful navigation through plantation paths where it is exceptionally easy to lose your bearings. The thermal vein sits entirely out of sight from public main roads.

Trackers can negotiate entry through two primary entry and exit routes:
- The Barangay Gym Route: Branching off near the public gym in Purok Mainit. This serves as the closest and most direct access corridor into the agricultural grid.
- The Casilac Route: Diverting along the perimeter access road of the nearby Casilak Mountain Resort.
⚠️ Navigation Warning: Because the entire landscape has been converted into a monoculture banana plantation, the overlapping access trails look nearly identical. There is a high risk of getting lost in the plantation maze. Do not hesitate to ask local residents for precise coordinates, as only the immediate community understands the trail network.
🧪 Environmental Reality Checks & Health Hazards
This stopover is highly rustic, and casual travelers looking for a traditional swim will find very little to see. The flow of hot water is incredibly small—only deep enough to wet your feet. If you want to experience more than a shallow foot soak, you must be entirely self-reliant and bring your own personal pail and water dipper (tabo) to scoop up the warm water.

1. Mineral Composition and Odor Dynamics
Unlike typical sulfuric hot springs that leave bright yellow or orange iron-sulfur deposits along the rocks, the stones, pebbles, and surrounding soil at Bukal sa Kanal are distinctly blackened. This indicates a highly specific mixture of volcanic elements and heavy organic sediment. The air carries a slight sulfuric odor, which is unfortunately mixed with a more foul smell. This heavy scent is a combination of accumulated trash left behind by irresponsible visitors and agricultural runoff settling in the drainage channel.
2. The Chemical Spray Hazard
Because this natural spring emerges directly inside the “kanal” (water drainage passage) of a commercial agricultural operation, it is exposed to industrial cultivation cycles.
☣️ Critical Safety Protocol
The surrounding banana plantation runs on a strict, regularly scheduled chemical spraying program. Lingering near the water or attempting to bathe here during or immediately after these maintenance windows poses a genuine risk to your health. Exercise extreme caution, check local spray schedules before entering the plantation paths, and avoid drinking or submerging open wounds in the water.
🌋 The Volcanic Connection & The Legend of the Resolute Water
Geologically, the naming of Purok Mainit (“Purok Hot”) serves a clear historical purpose. Local land elders state that this entire sector functions as a residual thermal basin of direct volcanic origin. The hot spring vein is widely believed to originate directly from the Apo Amacan Crater, a highly active volcanic system situated nearby in the municipality of Mawab, Davao de Oro. Despite the surface land being heavily converted into commercial agriculture, these deep, pressurized volcanic veins continue to push heated water to the surface.
The Folklore: The Water That Rejects Commercialization
While some residents claim the chemical-laced warm water possesses traditional healing properties, the most captivating aspect of Bukal sa Kanal is its modern folklore.
According to local accounts, an entrepreneur previously claimed the hot spring land and attempted to convert the wild vein into a commercial destination. The developer constructed a permanent man-made concrete pool and began charging visitors a ₱20.00 entrance fee.
Mysteriously, the moment commercial operations officially commenced, the hot spring completely dried up and ceased flowing. The business quickly lost its market, operations were completely halted, and the concrete structures were left to rot.
It was only recently, long after the commercial venture was completely abandoned and left to decay, that the natural hot spring naturally returned to its original drainage path. The local community tells this story as a warning, firmly believing that the volcanic spirit of the water strictly refuses to be commercialized or contained.

Q: How much is the entrance fee to visit the spring?
A: Access is completely free of charge (₱0.00). There are no gates, no structural caretakers, and no tourist check-ins.
Q: Can you fully swim or bathe in the hot spring pools?
A: No. The water flow is very minimal and shallow, usually only deep enough to wet or soak your feet. If you want to gather more water, you must bring a personal pail and water dipper. Furthermore, because it sits directly in an active agricultural runoff drainage line that undergoes regular chemical sprays, full body bathing is not recommended for health reasons.
Q: How do you find the entrance if there is no official signage?
A: You can enter the plantation tracks via two primary access points: either right next to the Purok Mainit Barangay Gym (the closer option) or by following the unpaved trail extensions along the Casilak Mountain Resort road. Be extra careful not to lose your bearings in the uniform rows of trees.
