We went to two gardens and I can't remember which was which. I believe the Royal Botanic Gardens were fairly flat and beautifully laid out in a formal style. Fitzroy Gardens was more natural and extremely hilly. At one point, the guide didn't notice that two elderly people went to sit on a bench because they couldn't make it any further up the hills. But he had the bus pull around to pick them up so they didn't have to continue to walk.
