Built back in the 1620s, the Shukkeien garden gets you a nice piece of tranquility in central Hiroshima, not too far from the downtown Peace Park area. The current incarnation reopened in the early 1950s after being rebuilt from scratch – the bomb wiped out pretty much everything, save for a lone stone bridge.
Strolling around the incredibly well kept greens on a calm afternoon is insanely relaxing and if you're up for it, tiny pellets of food can be bought and fed to the seemingly friendly fish and turtles roaming around the pond. And If it happens to be one of those incredibly hot days and you need to cool down a bit right after the garden ventures, the »Hiroshima Prefectural Art Museum« is well air conditioned and right next door, sporting decent art and a tiny café on the top floor.
The Shukkeien garden is an easy 15 minute walk from the peace park, to the north-east of the central parts of downtown Hiroshima. Should you opt for public transport, the »Shukkeienmae« tram station is right next by.
