There are ridiculous amount of things you can do for free or almost free in DC, thanks to just – one example – the Smithsonian Institution. Museums in themselves can eat up all of your day, after you just visit one or two, out of more than 20. But there also TONS of events every single hour of the day!
I bet you’ve never participated in a Lemur Feeding at 2PM at the Zoo, or the ever popular yearly “BOO at the ZOO”, starting from 5:30PM.
Most if not all events, are ACTUALLY FREE – just another reason why Washington, DC is an amazing city to visit.
