Going out in Tenerife is one of the only things to do of a nightime, and it's fortunate that Tenerife boasts some of the liveliest entertainment in the later hours.
There are obviously a lot of clubs, pubs, and bars where you can while the night away, however, there are also a lot of places where you can go and enjoy a meal and/or a themed night out.
Also, in Playa Las Americas, there is a theatre, and there is a cinema just outside Fañabe.
