Amazing place. You must visit! Most beautiful private garden in Johannesburg just next to the high away and the hollard offices. Before you go you have to book. R120 per person and the visit is 2 hours. You have a tour guide and some snacks afterwards. It was a pleasure to meet Mrs. Oppenheimer. Amazing lady. Chaos meets beauty. Loved the Japanese garden and the waterfall, the incredible collection of plants they have from all over the world, the bonsai garden, the history of the place, they have a huge library about South African history. The reason why there is no much information is because you have go there to see and feel. You will feel in total peace. What a hidden gem!
