The walled city itself is quite small, and you can walk through it in no time, but it can be a bit confusing; many of the streets look the same and it takes a while to get your bearings. Also there are a lot of steps and it can be quite a challenge in the heat. Good for burning off calories and making space for the delicious ice cream though. (My recommended flavour: strawberry cheesecake).
My favourite thing on my first day in Dubrovnik (apart from the strawberry ice cream) was just wandering around without any plan and discovering little hidden corners. However I also enjoyed a walk on the city wall (cost 100HRK).
I’ve noticed an increasing trend amongst ‘backpackers’ now to not actually bring a backpack and instead have a little suitcase on wheels. I’m a traditionalist and I stick with the backpack, although even I have been tempted to change (particularly when it’s hot and I have a month’s worth of clothes and shampoos on my back and the straps are cutting into the sunburn on my shoulders).
I was certainly grateful I had opted for a backpack when I got here though; the walled city, with its narrow cobbled streets and countless steps, is not the place for the wheelie bag, . Remember that you are going to have to walk from the city gate to your apartment, and it may well be up a narrow street with a lot of steps, so make sure you pack accordingly.
