The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

""The City between the wood and vines..." There have been links of friendship with Stuttgart since 1955. The “Image of Stuttgarg Garden” was offered to Cardiff by its twin city and designed jointly in October 2005 to mark the 50th anniversary of the twinning. The theme of the garden is the unique setting of the city of Stuttgart." Source: https://bute-park.com/attraction/stuttgart-garden
