Ardent Hot Spring

Ardent Hot Spring is a natural thermal spring resort located in Barangay Tagdo, Mambajao on Camiguin Island, Philippines. Situated at the foot of Mount Hibok-Hibok, it is heated geothermally by the active volcano. The spring features a series of man-made pools with warm mineral-rich water around 40°C. Developed as a public resort managed by the local government, it is one of Camiguin's most visited natural attractions for bathing and relaxation.

Visitors can expect a developed hot spring resort with several concrete pools of varying depth and temperature fed by naturally heated mineral water from Mount Hibok-Hibok. The setting is forested at the base of the volcano with views of surrounding hills. Facilities include swimming pools, cottages and picnic areas, changing rooms and food stalls. Visitors can soak and swim in the warm water, relax in cottages, take photos and enjoy the tranquil natural environment.

Ardent Hot Spring is geothermally heated by Mount Hibok-Hibok, Camiguin's active volcano. Its water temperature and flow are linked to volcanic activity, notably the 1948-1951 eruptions of Mount Hibok-Hibok that significantly affected the island's landscape and hydrology. The site was subsequently developed as a public bathing resort.

The spring is valued locally as a communal leisure and wellness site, with its warm mineral waters traditionally believed to have therapeutic and relaxing benefits. It is a long-established recreational destination for residents and visitors to Camiguin.
