Take the kids out with Michalis Kefalonia Fishing Tourism to learn how the Greeks fish. It's a fun and educational trip with a great lunch.
Once the boat leaves the harbor, the boat reaches the fishing grounds pretty quickly. You'll know you are almost there when you start seeing the crew get ready. When that happens, power up your cameras. As you do that, be sure to look around and find a good spot where you can set your camera for a few minutes while you inspect the catch as it is being placed on the deck or passed around.
The crew is really good about telling you which fish, crabs, lobsters, and other animals they caught. If you can remember what they told you, you can look up the animals later with the kids and learn even more about them.
It was quite surprising how many different types of animals they caught in their net. On our trip, they caught quite a few different types of crabs and lobsters. The most interesting lobster was the slipper lobster. They basically look like lobsters with riot gear on. They're kind of ugly looking bugs but they sure taste good.
They also pulled up a few animals our group had never seen before. As they found different, interesting animals in the nets, they would of course remove them and then pass them around for everyone to have a look at. After the animals made the "tour," they were dropped back into the sea.
The main course for lunch is whatever gets pulled up in the nets. There's a good chance lunch will be lobster if it is lobster season.
Lunch gets cooked on board. They serve it one a table, on the back of the boat. It's really good. You won't want to spot eating.
What To Bring
The boat will rock a bit when they slow down to pick up the nets. This is when you and the kids might start to feel a little sea sick. Be sure to bring along the appropriate sea sickness pills. Depending upon your kids age, you might need to have to packs, one for adults and one for children. Ideally you should take the pills before the trip starts.
You can definitely find a lot of shade on the boat. The back of it is completely covered. Nonetheless, you should bring sun screen and keep applying it throughout the trip.
Definitely bring your swimsuits and snorkeling gear. The boat will anchor in deeper water. But you and the kids can swim over to the shore and explore the rocks. You'll most likely find some fish and crabs.
They attach a ladder to the side of the boat so that you can easily climb into and out of the water. If the kids want some excitement, let them jump off the side of the boat. If they are doing that, just be in the boat to support them before they jump.
The water should be really clear.
Last Bit of Advice
Once you get back to the port, if you're not too tired, let the kids pull out their fishing poles. From the cement docks, you'll see little fish all over. If you didn't bring any bait, let the kids clean off the table after lunch. They should be able to find some scraps of food they could use for bait. Maybe they might even find some bits of lobster they could use.
