I only spent a day there but absolutely enjoyed the peaceful, relaxing atmosphere and charming ceramics work that can be seen all over the town. The gardens are quite nice, the Stairs are worth the climb too. Apart from being a UNESCO World Heritage Site, it is also a known skydiving spot, so there is really a little something for everyone. As with the rest of Sicily, highly recommend to drive and not rely on public transport. You can of course make your way around walking - everything is more or less 20 mins walk from city centre.
