[GIS] Setting Layer Visibility in OL3

openlayers

I am trying to toggle visibility of a GeoServer WMS layer.

The code below doesn't render the layer, regardless of if setVisibility is true or false 

var countryParks = new ol.layer.Tile({
                 title: 'Country Parks',
                 source: new ol.source.TileWMS({
                 url: 'http://localhost:8080/geoserver/opengeo/wms',
                 params: {"LAYERS": 'opengeo:country_parks'},
                 serverType: 'geoserver'    }),
});
countryParks.setVisibility(true);
map.addLayer(countryParks);

And this code does render the layer, true or false regardless

var countryParks = new ol.layer.Tile({
                 title: 'Country Parks',
                 visiblity: false,
                 source: new ol.source.TileWMS({
                 url: 'http://localhost:8080/geoserver/opengeo/wms',
                 params: {"LAYERS": 'opengeo:country_parks'},
                 serverType: 'geoserver'    }),
});
map.addLayer(countryParks);

How does one toggle layer visibility, if not as in these attempts?

In ol-3 the property is called visible and setVisible() not "visiblity" - see API
