Which province has the most recorded snake sightings in the Philippines?

Cavite, with 3,145 verified sightings on record, ahead of Metro Manila (2,535), Laguna (2,415), Rizal (2,378) and Bulacan (2,182).

Does a high sighting count mean a province has more snakes?

Not necessarily. It mostly means more people there are photographing snakes and reporting them. Cavite, Metro Manila and Laguna are some of the country's most densely populated provinces, so more residents are around to spot and submit a sighting.

How many provinces have recorded snake sightings?

Snakédex has verified sightings from 81 provinces. Of 49,830 total sightings, 43,060 include a specific province; the rest were submitted without one.

Which province has the most different snake species recorded?

Among the ten most-reported provinces, Batangas has the highest species count at 29, just ahead of Cavite and Laguna at 26 each and Pangasinan also at 26.

Where Snakes Are Seen Most in the Philippines by Province

August 18, 2026 · 4 min read · 1 view · Snakédex Field Notes

Snakédex's sighting database holds 49,830 verified snake sightings, and 43,060 of them carry a specific province. Sightings have been logged in 81 provinces. Cavite has the most with 3,145, followed by Metro Manila (2,535), Laguna (2,415), Rizal (2,378) and Bulacan (2,182), all part of the same crowded Luzon corridor. That ranking tracks where Snakédex's contributors live and look as much as it tracks where snakes live, so a low count in a province does not mean fewer snakes there, only fewer photographed and reported.

Snake sightings are not spread evenly across the country

Snakédex's map is built from 49,830 verified sightings, each one a photo submitted by someone who ran into a snake and posted it for identification. Of those, 43,060 carry a specific province. The rest came in without enough location detail to place on the map. Between the located sightings, 81 provinces have at least one confirmed record.

That is a wide spread, but the sightings are nowhere near even. A handful of provinces around Metro Manila account for a disproportionate share of the total, and that pattern says as much about the Philippines' population map as it does about its snakes.

The ten provinces with the most recorded sightings

Ranked by total verified sightings, the top ten are:

Cavite, 3,145 sightings, 26 species recorded
Metro Manila, 2,535 sightings, 22 species recorded
Laguna, 2,415 sightings, 26 species recorded
Rizal, 2,378 sightings, 23 species recorded
Bulacan, 2,182 sightings, 24 species recorded
Batangas, 2,157 sightings, 29 species recorded
Pangasinan, 1,748 sightings, 26 species recorded
Cebu, 1,604 sightings, 22 species recorded
Benguet, 1,602 sightings, 23 species recorded
Davao del Sur, 1,486 sightings, 24 species recorded

Together these ten provinces account for 21,252 sightings, close to half of every located sighting in the database and about 43 percent of all sightings, located or not.

Why the CALABARZON and Metro Manila corridor dominates the list

Six of the top seven provinces, Cavite, Metro Manila, Laguna, Rizal, Bulacan and Batangas, sit in or immediately around Metro Manila. This is the most densely populated part of the country, and it shows in the data: more houses border more open lots and creeks, more people carry a phone that can take a usable photo, and more people know the Snakédex Facebook group exists to send that photo to.

None of that means this stretch of Luzon is unusually rich in snakes compared to, say, Mindanao or the Visayas. It means a snake that turns up in a Cavite backyard is far more likely to get photographed, identified, and logged than one that turns up somewhere with fewer people around and less phone signal. Luzon is also where two of the country's medically important elapids overlap in range: the Northern Philippine Cobra (Naja philippinensis) is common on the island, while the related Southern Philippine Cobra (Naja samarensis) takes over in the Visayas and Mindanao, which is part of why provinces like Cebu and Davao del Sur show up on this list too.

Species count and sighting count don't move together

A province with more sightings does not automatically have more kinds of snake. Batangas has fewer total sightings than Cavite, 2,157 against 3,145, but it has the most species of any province in this list, 29. Cebu and Metro Manila both sit at 22 species, the lowest count among the ten, despite Metro Manila ranking second in raw sightings.

Read together, sighting count is mostly a measure of reporting volume, while species count is a rougher proxy for habitat variety: a province that spans lowland farmland, forest edge and coastline will tend to turn up more kinds of snake than one that is mostly built-up.

What a low count in your own province actually means

If your province is not on this list, that is not evidence it has fewer snakes. It is evidence that fewer sightings from it have been submitted and verified. A quiet province on the map may simply have fewer Snakédex contributors, less mobile coverage, or a smaller population near the kind of habitat where snake encounters happen at all.

Snakédex is a record of what people have photographed and had verified, not a biological survey. Treat any single province's number as a floor, not a ceiling: at least this many sightings happened here, with no claim about how many more went unphotographed or unreported.

Checking what has been seen near you

The full breakdown, down to individual sightings, is on the Snakédex map. It shows every province, not just the ten with the most activity, and you can zoom to your own city or town to see what has actually been logged nearby. If you want to test how well you can tell one Philippine species from another before you rely on your own eyes in the field, try Who's That Snake?.

If you come across a snake yourself, the safest move is the same one that applies everywhere on this list: leave it alone and move away, and treat any suspected bite as a medical emergency that needs immediate hospital care.
