About this spring
A stunning natural wonder featuring a steaming waterfall rich in sulfur that cascades down a multi-tiered rock face encrusted with vibrant yellow mineral deposits. The thermal water collects into natural rock pools along a warm riverbed below, allowing visitors to bathe directly under the hot waterfall. The heavy mineral concentration gives the entire canyon a distinct, ethereal look.
Highlights
History
The name of this spot translates simply to hot in Filipino, but its true history is deeply woven into the identity of the indigenous Mandaya and Mansaka peoples.
These tribes are celebrated for creating dagmay, an intricate textile woven from abaca fiber using ancestral patterns that weavers often visualize in their dreams. The surrounding province of Davao de Oro is one of the richest gold and copper mining districts in Southeast Asia, packed with dense underground minerals. The brilliant yellow sulfur cascades at this spring are a beautiful, visual reminder of the heavy mineral wealth hiding beneath the mountain.
Local guide
This spot is easily one of the most visually stunning natural wonders in the country. You will walk into a rocky canyon and find a steaming waterfall cascading down a cliff covered in brilliant yellow sulfur deposits. The hot mineral water collects into natural stone pools right along the riverbed.
Bathing directly under a warm, rushing waterfall is an incredible, tingling sensory experience. Wear an old swimsuit because the intense yellow minerals can permanently stain light fabrics. Bring a dry towel and plenty of drinking water to stay hydrated in the steam.
The site is highly popular on weekends, so a sunrise visit on a weekday offers the most peaceful experience. Small local stalls near the entrance sell basic snacks like boiled bananas and instant coffee. The sight of that golden, steaming cliffside will stay with you forever.
Mineral chemistry
Sulfuric hot springs are among the most studied in balneology worldwide. The sulfur compounds, primarily hydrogen sulfide and thiosulfate, have documented antimicrobial and anti-inflammatory properties. Regular bathing is associated with relief from chronic skin conditions including eczema and psoriasis, as well as joint inflammation and muscle soreness. Sulfuric waters have been used therapeutically across Asia and Europe for centuries.
The distinctive rotten-egg smell dissipates quickly after leaving the bath. Avoid if you have a sulfur allergy, very sensitive skin, or respiratory conditions. Remove silver jewellery before entering — sulfur will blacken it permanently.
Simple thermal springs have lower dissolved mineral content but are valued for the pure therapeutic effect of heat immersion itself — easing muscle tension and improving circulation. Considered the gentlest introduction to hot spring bathing.
Standard precautions apply: avoid bathing within 30 minutes of eating, keep soaks to 10–15 minutes for first-timers, and hydrate before and after.
