About this spring
A secluded, pristine forest sanctuary nestled deep inside a 300-foot ancient volcanic crater between Mount Makiling and Mount Banahaw. It features multi-tiered, crystal-clear natural thermal pools surrounded by a dense, preserved rainforest canopy filled with wild ferns and centennial trees. The experience emphasizes raw natural preservation and serene forest bathing.
Highlights
History
This remarkably preserved sanctuary flourishes deep inside an ancient, three-hundred-foot volcanic crater that sits quietly between two of Luzon's most famous peaks.
One of these is Mount Banahaw, a potent volcano considered deeply sacred by local mystic sects, folk religions, and spiritual pilgrims who seek miracles on its slopes. During the logging boom of the 1970s, the owners of this crater estate made the unusual decision to ban all farming and development to save the wilderness. Because of that choice, you can experience a wild thermal ecosystem exactly as it looked to ancient Tagalog tribes.
Local guide
Walking into this sanctuary feels like stepping right into a prehistoric world. You will descend into a deep, lush volcanic crater surrounded by massive centennial trees and wild giant ferns. A network of clean wooden boardwalks guides you to multi-tiered, crystal-clear thermal pools.
The water is remarkably clear and odorless, letting you see the smooth river stones beneath your feet. Pack a premium swimsuit, a light cover-up, and a good camera for the breathtaking forest views. This is a premium eco-resort experience, so the guest count is always intentionally limited.
The entry fee includes an excellent buffet of traditional Filipino dishes served in an open-air pavilion. Arrive right at opening time to maximize your day pass and experience the jungle at its quietest hour. The sound of wild birds calling through the canopy is absolutely magical.
Mineral chemistry
Alkaline springs (pH above 8) are known for their skin-softening effect, sometimes called "beauty water" in bathing cultures across Asia. The high pH saponifies skin oils, producing a characteristic silky feel on the skin surface.
The slippery feeling underfoot in highly alkaline springs is normal — take care when standing and walking in the bath. Avoid prolonged soaking if you have dry or sensitive skin.
Bicarbonate springs cleanse and soften the skin surface, removing excess sebum without stripping the skin's acid mantle. Traditionally recommended for acne-prone skin and sensitive skin types.
Bicarbonate springs are generally among the most gentle and well-tolerated onsen types.
