I've been trying to locate the updated ferry schedules to see if it makes sense for us to do a day trip over from Positano to Salerno. Do any locals or experts know if there are ferries that go back to Positano from Salerno any later in the day than 15:30? From what I'm seeing on the Cooperativa site, it won't really give me much time to spend the day in Salerno if we can't leave Positano until 10:00 and then need to be on the return ferry by 15:30....unless there are some companies that go that I cannot find.
If I do decide to go for the day - should I just try to walk around the historic center and maybe enjoy a nice lunch, or is there enough time to see the Castella as well?
Thanks for your help.
