About this spring
A unique thermal destination featuring multiple natural hot spring pools built into a dramatic, towering lahar canyon wall. The pools are naturally heated by the geothermal activity of nearby Mount Pinatubo. Accessing the canyon requires an off-road journey through volcanic ash fields, making it a premier adventure-wellness spot.
Highlights
History
The thermal fields here today are a direct, living consequence of the catastrophic 1991 eruption of Mount Pinatubo, the second largest volcanic event of the twentieth century.
It was the indigenous Aeta people, the ancient guardians of these mountain slopes, who first noticed the unusual steam vents and bravely warned the lowlands before the mountain blew. Tragically, the subsequent lahars displaced thousands of Aeta families from their ancestral lands. Today, these hot springs stand as a unique community-led eco-tourism project, turning a landscape of past destruction into a source of survival.
Local guide
Your journey begins with a thrilling ride in a 4x4 open-top jeep through a massive canyon made of grey volcanic ash. When you arrive, you will see multiple stone pools built directly into the towering cliff faces. The sulfuric water bubbles up naturally at high temperatures, creating a dramatic outdoor spa.
The bathing experience is highly active, transitioning from hot pools to a unique warm sand spa where staff gently bury you in volcanic ash. Bring an extra change of clothes and a waterproof bag for your phone. The sand feels surprisingly heavy and warm against your body.
It is best to book an early morning slot to avoid the intense midday heat inside the sun-baked canyon. The package usually includes a buffet lunch at the base camp, featuring classic Filipino dishes like savory pork sisig. The sound of the jeep tires crunching on ash will stay with you for days.
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.
