The city in itself is, in my opinion, not worth wisiting: nothing even remotely touristic, except maybe for the view, and nothing especially beautiful. However, I thought it was very interesting to see a bit more of how the people lived in Cuba, with communism and all. That said, I’ve only been in Holguin for a day (I stayed at a resort nearby) so I obviously didn’t get the time to see everything there could have been to see. If you want to go there, I’d suggest visiting the organ fabric, although it’s probably not what you’d expect ;)
