You can also find a Hot Spring in Borac Barangay, part of Naval Municipality, Biliran Island.
This is not so easy to find so when your in Borac it might be best to ask a few of he friendly locals to point you in the right direction.
From the main road you need to look for a small track or path between the houses heading in the direction of the sea. After walking along there you come to the steep slope down to rice fields and a narrow path across them going to the Hot Spring. I don't think this spring gets many visitors but it's not far from Naval and is still interesting to have a look at and feel how warm the water is.
The Biliran Volcano is a large Compound Volcano or Complex Volcano forming the Island of Biliran off the north coast of Leyte Province in the Visayas region of the Philippines. Biliran Island contains many prominent andesitic lava domes, five fumarole fields and the most recent activity was a phreatic explosive eruption and debris avalanche at a thermal area at Mt. Suiro in 1939 with ashfall over Caibiran on the east coast. Possible other Biliran Volcano eruptions are said to have taken place at Mt. Pananao between Almeria and Kawayan in 1669 and another in Caibiran around 1800 near the site of the current Biliran Geothermal project. The Biliran Volcano is listed as one of the few active Volcanos in the Philippines and was monitored in 1954 when it was feared the Volcano was close waking from its sleep. The Island has many Thermal areas, Mud Pools and Hot Springs such as in Libtong in Naval Municipality and the Mainit Hot Spring in Caibiran that have become popular tourist attractions. Biliran and Leyte Province are also prone to earthquakes as they are on the Central Leyte Fault line, part of the Philippine Fault Zone. The Fault line passes right up the spine of Leyte Island and then along the seabed between Biliran and Calubian Municipality in Leyte Province.
