Huapango
Especially at the weekend you can see this typical traditional dance at the zocalo. A guitar is been played, someone sings and two people are dancing on a wooden platform. It is very rythmic and well-known in Catemaco.
Salto de Eyipantla
West of Catemaco
The big waterfall nearby the city is worth a visit. Take a taxi, or 2 buses, to get there.
Baños
All over the place
No joke, Catemacos toilets seem to be a bit famous. And, indeed, the bigger, colorful ones are worth a visit.
