Nice Gardens and Castle, but just far too expensive. There are no discount rates for students or locals and the child rate only goes until age 14. The cafe is good and reasonably priced, but there's no incentive to just come and visit as there is an exorbitant entry fee.
The gardens are well maintained, but a bit small and not much compared to other free gardens in Dunedin, such as Glenfalloch or the Botanic Gardens.
While we are at it, it's less of a castle and more of a mansion.
I would recommend Lanarch Castle if you're visiting Dunedin as it has an interesting history, is picturesque and offers good views, but for locals it is just to expensive to be an attractive option.
