This is not a major site, but it's fun to stumble upon. This is a somewhat regular neighborhood playground, except it has a television set. The kids play on the swings while adults fall asleep in front of cartoons. It's kinda strange, kinda amazing.
The playground is not easy to find. W.A. Silva is the road that leads up from Wellawatte junction. Ash Tip Road is the last road on the left before the next junction. You can also take a winding route down from the fork of Havelock Road.
