Amsterdam is the perfect place to party! Most clubs in Amsterdam are open at 10 pm and stay open until 4 or 5 am. However, usually things only get going after midnight, so try and keep yourself awake. Most clubs in Amsterdam are members only but with a little negotiating you can sometimes get around this. Some clubs like the Melkweg offer one night memberships for a few euro.
Amsterdam offers a wide range of music venues. Try to catch a performance of the Netherlands Philharmonic Orchestra that performs in the Beurs, a turn-of-the-century stock exchange. In June the city of Amsterdam hosts the Holland Festival—opera, orchestra and dance performances.
