The ferry from Salerno to Amalfi town was set to take about 35 minutes, and we were debating whether to risk the windswept top deck, fearful our packed lunches might fly into the Tyrrhenian Sea. (My father and I were taking a pragmatic approach on our Italian holiday, opting for light midday meals to save space for the primo and secondo courses at dinner, and ample lemony desserts.)

As our ferry sped across glittering water, we admired the views as the Amalfi coast unfolded, incandescent with charm. But we could also see the crawling traffic on the narrow roads that cling to the cliffs. That could have been us, up there in one of those toy-sized rental cars, squeezed between a tourist coach and a fed-up local leaning on their horn. Thankfully, we were on a boat instead, sea breeze in hair and coffee in hand.

The Amalfi coast has a reputation that draws tourists from all over the world. It seems everybody wants to see this string of sorbet-coloured towns, to wander the narrow streets where houses climb the hills like stacked blocks, and to sip limoncello while gazing out across the impossibly bright, blue waters. But as eager as I had been to experience these famous graces, the idea of white-knuckling it on hairpin turns in a Fiat 500, inches from certain ruin, didn’t seem like my idea of fun. That’s when an Italian friend gave me some priceless advice: stay in Salerno – it’s a nice town with good restaurants, and you can do all your excursions via public transport from there.

Salerno is tucked just under the Sorrentine peninsula and about half an hour south of Naples on the fast train. It’s an ideal base for jumping on trains to inland attractions such as Pompeii and Paestum, but also for catching ferries to every destination along the Amalfi coast, as well as Capri and Sicily. What’s more, Salerno is a more affordable base than the honeypot towns of Positano or Ravello, where accommodation and restaurant prices are around double what you’d pay here.

Originally a Roman colony, Salerno was reshaped by the Normans in the 11th century. It’s a pleasant and relaxed town to wander, its wide and luxurious promenade dotted with palm trees, benches and street performers. What it lacks in Amalfi glamour, it makes up for with a more authentic tableau of local Italian life. (After a day of eating overpriced ice-cream from hollowed-out Amalfi lemons, we found Salerno’s lack of performance refreshing.)

Dad and I got a holiday rental on the edge of the historic centre, near Salerno Cathedral, which houses the relics of Saint Matthew. We wandered in one morning and were surprised to find that although the duomo is on the modest side, the crypt is a real showstopper, with intricate marble details from top to bottom. The town is also home to the Schola Medica Salernitana, which dates back to the 9th century and was the pre-eminent source of medical knowledge in its heyday, before closing in 1811. Today, the adjacent Garden of Minerva botanical terrace is the city’s most picturesque attraction. Its organising principle is the four humours of man (the Ancient Greeks theorised that our temperament and health are dictated by a balance of blood, phlegm, black bile and yellow bile). That’s certainly something to think about while wandering the gardens, where the plants are labelled according to which “mood” they affect.

But Salerno is all about the food for me, most notably the glistening, black squid ink pasta dish I ate at La Botte Pazza and still salivate over months later. The menu, scribbled on a tiled wall, described the dish simply as spaghetti mare. The wine came out of taps in the wall, and the buzzy atmosphere only got louder as the evening progressed. The bonhomie was all the more welcome after spending the day wandering among the ghosts of Pompeii (40 minutes up the coast by train), which was buried in ash when Mount Vesuvius erupted nearly 2,000 years ago.

Another worthwhile rail excursion is to Vietri sul Mare – the first town in the string of pearls that make up the Amalfi coast, and the only one that can be reached by train. We hopped on an eight-minute service out of Salerno for a wander through the town famous for its colourful ceramics, but also because I wanted to swim – Salerno’s seafront has a nice promenade, but beach lovers are left wanting.

You can swim in Amalfi town too, but the beach in this more famous spot was already getting busy when we visited in late March. As much as I enjoyed Amalfi, I felt relieved to be there early in the season – its narrow streets weren’t built for crowds.

Vietri sul Mare is sleepy in comparison, and I was thrilled to find a peaceful stretch of sand, where I changed quickly under the arches before running in for a bracing dip in the turquoise water.

For Dad, who takes a dim view of anyone who goes in the sea in March, Paestum was more of a highlight. After speeding south for about half an hour, the train dropped us off in the middle of nowhere, by a gravel road that promised a 10-minute walk to the ruins of the once-great Greek city. We were in our element now – at Paestum, visitors can wander about freely as the approximately 27-hectare (66 acre) site unfolds, with the occasional noticeboard sharing a story of what used to be here, but mostly leaving it to your imagination.

Paestum’s crown jewels are the three temples looming large and golden in the landscape; they are about 2,500 years old yet very well preserved. Dad was pleased to find a working model of Archimedes’ screw, an ancient hydraulic tool for elevating water, while I was tickled by the Tomb of the Diver, with its fresco of a gentleman diving into a pool, starkers.

Osteria Canali gave us our last meal in Salerno, and again we had the pleasure of being surrounded by local people in an inviting neighbourhood taverna. The regional menu was rich with aubergine and mozzarella, and then came the main course of baccalà – a piece of white fish with figs, wrapped in paper and simmering in its own juices. More creamy Amalfi lemon desserts to finish, of course, and we figured we should try the limoncello as well – when south of Rome, right? But as much as I like a citrus tang, this was finally too much lemon for me.

Choosing Salerno as our base opened up a different side of the Amalfi coast, allowing us to come and go by boat and train without the stress of traffic jams and impossible parking situations. We only missed a train once, but another came along half an hour later, and while we waited there was nothing to worry about except where to go for ice-cream.

Intercity trains run from Naples Central to Salerno and take about 35 minutes (€9.50). Regional trains from Salerno central take about 40 minutes to Pompeii (€2.80); 30 minutes to Paestum (€3.40); and eight minutes to Vietri sul Mare (€1.40). Timetables at trenitalia.com. Several ferry companies run year-round services from Salerno to the towns along the Amalfi coast. The Travelmar passenger ferry sails direct to Amalfi town from Salerno’s Concordia terminal (35 minutes, €26 return). Plan your journey with FerryHopper
