Fireflies on the Abatan: Why the Kayak Trip and the Boat Trip Aren't the Same Night

After dark, the mangroves along the Abatan River fill with fireflies – not a scatter of them, but whole trees lit from the inside, blinking more or less in time. The Philippines is one of the few places where they still gather in that density, and Bohol is one of the few places in the Philippines where you can get close without a motor.

That last part is the whole decision on this page.

Two different nights, sold under one heading

Search for fireflies on Bohol and you get two quite different things.

The kayak trip launches from Cortes on the Abatan, in the dark, with a guide, and goes quietly into the narrow channels where the mangroves close over your head. The five-hour version with the mangrove tunnels is €68.99 and holds a 5.0 rating from 53 reviews; a second Abatan kayak trip runs €53.13 at 4.9 stars from 20 reviews.

The motorboat cruise is the cheaper, shorter, much more common version – four hours at €28.12, 4.1 stars from 42 reviews, with the words nature-dependent in its own title. There are other motorboat cruises on the Loboc River, including one at €27.66 for three hours that sits at 3.1 stars from 30 reviews.

Look at that spread again, because it is unusually clean for this island: the two kayak trips above hold 5.0 and 4.9; the rated motorboat versions in our inventory sit between 3.1 and 4.1. The price roughly doubles. The ratings say people think it is worth it.

Why a paddle is better than an engine, specifically

Three reasons, and none of them is atmosphere.

Fireflies respond to light and vibration. An engine puts both into a narrow channel. A kayak puts neither, which is why the animals stay where they are instead of moving up into the canopy.

The channels a kayak can enter are the good ones. The mangrove tunnels are narrow and shallow. A motorboat stays on the open river and shows you the trees from a distance.

Propellers damage mangrove roots, and the people who run the Abatan trips are the ones replanting them. The guides are members of the riverside communities, and a paddling trip is the version of this business that does not undo its own work.

The Abatan is worth the trouble in daylight too. It runs through five of Bohol’s municipalities – Catigbian, Antequera, Balilihan, Maribojoc and Cortes – and 32 mangrove species are recorded along its banks. For a single river system that is an extraordinary number, and it is why there is conservation money here at all.

What the evening actually looks like

You are collected in the late afternoon, because the launch is at dusk and the river is inland. The paddling itself is not athletic – flat water, no current to fight, a guide who sets the pace. Then the light goes, the guide stops talking, and you sit.

Several of these trips end with a home-cooked meal with the community that runs them. That is a large part of why the five-hour version costs what it does, and it is the part people write about afterwards.

What a good guide will ask of you, and why:

• No flash and no torch pointed at the trees. White light is exactly what a firefly’s signal is competing with.
• No catching them, and no holding one in a cupped hand for a photograph.
• Quiet. Not solemn, just not a party boat.
• Dark clothing helps, and so does turning your phone screen brightness down before you go.

Your photographs will be bad. Everyone’s are. Point a camera at this and you get a black rectangle with three green specks; the eye sees something a sensor cannot. Make peace with it beforehand and the evening is much better.

The thing that decides whether you see anything

The moon. A bright moon washes the display out. A new moon, or an evening before the moon rises, is what you want, and it is the single biggest variable – bigger than the operator, bigger than the price.

The rain. Heavy rain ends it. None of these trips promises you fireflies – one of the motorboat listings carries the nature-dependent caveat in its very title.

Both of those lead to the same practical rule: put the firefly trip in the middle of your stay, never on the last night. If it is cancelled on day three you can go on day five. If it is cancelled on the last evening, that was your one chance.

Is it worth the money?

At €68.99 it is one of the more expensive single evenings on Bohol – more than the countryside loop that fills a whole day. Judged as a sightseeing hour it is poor value. Judged as the hours on the water, a meal with the people who look after the river, and a thing you cannot do in many other places, most people come back saying it was the evening they remember.

If the budget says no, the motorboat version at €28.12 still shows you fireflies. You will see them from further away, and you will share the river with an engine.

With children, check the operator’s age limit on the booking page before you plan around it – kayaks have one, it differs between operators, and the trip runs long past bedtime. Bohol with kids covers where that line usually falls in a family week.

More of the island’s water and forest, and the 50 trips that cover it from €18.92: waterfalls, caves and rivers. For the paddling rather than the fireflies, adventure tours start at €16.74.
