One of my favourite Hobart things to do is visit the botanical gardens. This was one of my favourite things to do in Wellington and Oxford, too. The Hobart version is, I think, particularly good.
There are ponds with ducks (watch out, its spring time, which means crazy duck business), bridges, water lillies and waterfalls.
There are mass plantings, of course. The ranunculi were spectacular, but earlier in spring the tulips were pretty good too. I'm happy to say that there are just a few of these, but well concentrated to give you a fantastic surprise. There is also a wonderfully large tree section - an oak grove, a pinetum, and various Australian bits and bobs. Right by the toilets is a fantastic collection of warratahs. And although we didn't go this weekend, I happen to know that the restaurant does an excellent cake and coffee for elevenses.
