Hidden Valley Springs is a natural volcanic spring resort in Calauan, Laguna Province, Luzon, Philippines, where sodium-mineral waters from several distinct volcanic springs are channelled into naturally landscaped pools set within a collapsed volcanic crater covered in dense tropical forest — creating an otherworldly jungle bathing environment of remarkable natural beauty just two hours from Manila. The resort's location within an ancient volcanic crater, accessible by steep canyon pathways through lush rainforest, creates a dramatic sense of descent into a hidden world that gives the resort its evocative name and distinctive character among the many hot spring facilities of the Laguna volcanic zone. The multiple distinct springs within the crater complex each have slightly different mineral compositions and temperatures, providing a variety of bathing experiences within the same jungle-enclosed volcanic setting, making Hidden Valley one of the most unusual and memorable natural thermal attractions in the Philippines.
