The Wheelbarrow in Notwane, about 25 minutes outside of Gaborone on the A1 South, is a nursery with picturesque gardens available to hire for special events. The Tea House has a nice menu. There is also a playground and plenty of outdoor lawns for children to use up some energy on, and there are riverside views.
They frequently hold special events such as Mother’s Day luncheons, so follow them on social media to see what food will be on offer.
You can also pick up some lovely water-wise plants for your own garden while you’re there.
