The cathedral is nice with special attention for the portal portraying Adam and Eve. The climb is not difficult until the last part, when the steps get pretty narrow and some people may have difficulty to go through the opening to access the last stage of the tower (not recommended for people with vertigo or with small children). You will have a nice view of town, the fortress, the canal and the ocean. The fact it costs 25 kuna also prevents it from getting overcrowded.
