Carnival. Crazy way to celebrate a religious holiday. The whole country parties. The best place to participate is in a small town in the interior- Las Tablas. It’s the scene of beautiful parades and crazy drunken parties. 
The floats are amazing
Fireworks go on for hours
Prepare to get soaked by water trucks and kids with water pistols
Water tuck sprayed these kids in a cantina while the parents hang out, dance and drink beer
Little drummer in one of the many parades
Beer cans. A massive amount of alcohol is consumed. But amazingly despite that I saw no acts of violence and felt safe at all times.
