I have been looking for braai spots which are open to the public and it doesn’t appear that there is much choice. But the one I have found looks good.
You can hire a site for either the morning or afternoon at the Queen Elizabeth Park. A beautifully maintained park in Waterlooville which you get to, off the A3 to London.
A road winds its way from the Visitors Centre to the top parking area where there are a couple braai sites and a lapa with a pizza oven
There are twelve family sites and three more that cater for larger groups and events.
