Tram 18 will take you to the Pretoria Botanical Garden and Zoo so both attractions are easy to reach. The Botanical Garden is free and a walk is pleasant. We just walked in front and didn’t see the greenhouse. The front lawn, garden, flowers and fountains are well maintained and clean. Walking around the front garden is easy to enjoy from all angles. The road is flat and wheelchair accessible and accessible. Benches are placed along the road, give us a breath and rest, and enjoy the botanical garden.
