Swim in the Trevi Fountain#9 of 62 things to do in Rome
Swimming in the fountain is strictly forbidden, and fine for swimming is about €500.
If you are not afraid, then you can take a dip in the fountain late at night, when there are fewer tourists, the streets lit up with lights and the guards are little distracted.
Remember that you only have time to dip, because the police can catch you in any minute.
Oddviser, of course, does not recommend this adventure :)
