Taking a taxi from Salerno along the Amalfi coast can be a good and fast option. Normally you can catch a taxi near the docking area. If not, you find taxi’s at Piazza Della Concordia, where the shuttle buses bring you. Roundtrips along the coast to places like Amalfi, Ravello, Positano and Sorrento can cost between € 150 and € 200 per taxi.
It’s also possible to go to Pompei and Mount Vesuvio by taxi. You will pay around € 150 per taxi, one-way.
