San Pablo Volcanic Field, Volcanic field in Laguna Province, Philippines.
San Pablo Volcanic Field is a mountain region in Laguna Province, Philippines, made up of over 200 volcanic formations including maars, crater lakes, and scoria cones. These formations are spread across a wide area and were each shaped by different types of volcanic activity.
The last recorded volcanic activity in this area dates to around 1550, marking the end of a long period of geological change. Several of the crater lakes had already formed in the centuries before that through explosive underground processes.
The communities surrounding this field have long depended on the mineral-rich volcanic soil for farming rice and tropical fruits, shaping their daily work and way of life. These agricultural practices remain central to how people use and relate to the land around them.
The area has several hiking trails leading to different crater lakes, though the paths and terrain vary a lot from one lake to the next. Going with someone who knows the area well makes it easier to find your way and reach the more remote spots.
Sampaloc Lake, one of seven crater lakes near the city of San Pablo, is the largest maar in the area and sits right at the edge of the urban center, within walking distance of the streets. Having a deep volcanic lake this close to a city is quite rare anywhere in the world.
