One of the neatest things we've discovered is the Queen's Park Savannah. This is a large tract of land (the road around it is 3 km) in the centre of Port of Spain. It is surrounded by mountains and there is a "pitch" walk way all around it.
Essentially, most of the area is a hay field. The grass is cut with a bush hog, (and not very often).
Despite this, it is used by hundreds of people everyday! When we go, it's usually to play Frisbee. We just set up some cones and play. There are always soccer games and cricket happening. Usually there are countless people running or walking around the outside. Occasionally someone is flying a remote control plane.
While some of the areas have goal posts for soccer or rugby, there is no "booking the field". People just go! and PLAY!
At night, in the summer at least, and on weekends the rest of the year, a food court magically appears at about 5pm. There is bar-b-que chicken, juice bars, ice cream, gyros...If you like coconut water, you can always get fresh coconuts chopped open with a machete!
This photo, while not ours, captures it nicely
