This program features our Chefs’ seasonal and regional recipes based on the healthy Mediterranean diet. Our Secret Garden program takes you on a culinary tour of the famed Amalfi Coast and its Mediterranean cuisine with our team of chefs, all while you soak up the culture and visit fun artisan food stops and landmarks.

We welcome you to our professional Mediterranean kitchen for hands-on Positano cooking classes where you will create a series of authentic recipes using different recipes, techniques, and styles.  This one-of-a-kind Positano and Amalfi Coast cooking vacations brings you up close and into the kitchen of the Amalfi Coast’s most celebrated chefs – the ideal tour for the real foodie.

Positano Cooking Classes

Our cooking programs in Positano include three hands-on cooking classes (you may always add on additional cooking classes if you’d like); lunch or dinner follows and everyone enjoys the food that was prepared in the cooking class with wine included.

Our chefs learned the secrets of Italian cooking – starting with their grandmothers – to culinary school. In each cooking class in Positano, you’ll transform farm-to-table produce and organic fruit and vegetables into full-course menus featuring traditional fare.

Each Positano cooking class includes preparing antipasto: fiori di zucca ripieni – stuffed squash flowers, arancini, crochette di patate, involtini di melanzane, polpettini di melanzane, pasta: gnocchi, ravioli Capresi and scialatielli, a main course: spigola al limone, pesce all’acqua pazza, vitello Positanese, pollo con le erbe e limone, and dessert: torta Caprese, torta Vesuvio, babà soaked in limoncello, gelato and crostate, to name a few.

During the week, you will also learn the technique of making authentic Neapolitan pizza with our award-winning pizzaiolo, pizza-maker, who learned to make la vera pizza Napoletana, real Neapolitan pizza, in Naples. This authentic pizza-making class shares the secret recipe for mixing, kneading, and stretching delicate pizza dough and baking it at a high temperature in a wood-burning oven for a perfect crispy crust.

If pasta is your favorite, you can choose to add on our Pasta Making Workshop where you will make additional fresh, hand-made pasta with seasonal sauces. Fresh pasta making is an art in Italy, and in Positano, you will learn to make it step-by-step! Believe it or not, Italy boasts over 1,000 different types of pasta, including gnocchi, ravioli, tortellini, cannelloni, orecchiette, casarecci, and garganelli, to name but a few.  Experience southern Italy’s cooking styles, cuisine, and excellent wine in this unique food lover’s cooking program in sunny Positano!

If you are an advanced cooker or chef, we can offer the same Secret Garden Cooking Tour with advanced cooking classes and make it a tailor-made menu for you. Just let us know.

The Secret Garden Positano™

Our charming Secret Garden Positano program is hosted at your choice of accommodations:  a B&B, villa, 3, 4, or 5-Star property located in the center of town and overlooking the sea. Cool ceramic tiles line each bedroom, with a private bathroom and shower in each room. Additional amenities include a hairdryer, safe, refrigerator, and air conditioning. Breakfast is served each morning, and daily maid service is provided for your convenience.  Positano is filled with flowered pergolas and greenery, vertical cliffs jut from the sea, and its one winding road circles the town.

The Secret Garden is truly a magical setting, terraced with lemon trees, and plush green gardens and set under spectacular bougainvilleas overlooking the sea. Guests can sunbathe on the beach or relax at one of the cozy sidewalk cafés with a freshly squeezed lemonade. Step out your door and stroll past cafés, bookshops, and trattorias that spill onto the sidewalk. A panoramic view spans Li Galli Islands and the Amalfi Coast. The Tyrrhenian Sea is literally at your feet, and the beach is just a short walk away. As the sun sets, sit back on your terrace and watch the world-class yachts and local fishing boats ripple through the cerulean waters. Shuttle boats connect from each of Positano’s beaches and sail along the Amalfi Coast. From Positano’s port, you can also take a water taxi or a private boat service to Sorrento, Ischia, Capri, Amalfi, and Naples.

Mediterranean gardens and lemon groves dot the Amalfi Coast, and gardens grow almost all year long producing red cherry tomatoes, plump eggplant, zucchini, and sweet oranges. Olives also grow in abundance thanks to the warm Mediterranean climate, fertile volcanic soil, and salted sea breeze, all of which provide perfect growing conditions. Organic herbs of basil, sage, parsley, oregano, rosemary, and mint, line gardens and fill pretty terracotta pots set on terraces. The local organic herbs that we grow in our garden are used in our cooking classes, along with our own first cold-pressed extra virgin olive oil.

Positano ~

“Positano bites deep, it’s a dream place, that isn’t quite real when you are there and becomes beckoningly real after you have gone.”  John Steinbeck.

John Steinbeck lived in Positano in 1953 and wrote, “Positano bites deep, it’s a dream place, that isn’t quite real when you are there and becomes beckoningly real after you have gone.”

Over time, Positano has attracted artists, writers, and photographers who came to capture its magic. It is a little Moorish-style village that was discovered by American and British troops at the end of World War II. Positano’s small winding streets are filled with tiny cafés, terraces, and artisan shops selling ceramics, limoncello, and antiques. Take a walk along the stone pathway, the one little street that leads to the beach. Visit the parish church of Santa Maria Assunta in Piazza Flavio Gioia, a Romanesque structure that was completely rebuilt in 1700. The people of Positano celebrate the town’s feast day every August 15th, when the locals carry the statue along the beach with a parade of musicians. A spectacular fireworks display follows.

In the 10th century, Positano was part of Amalfi’s Maritime Republic and rivaled Venice as an important mercantile power. It was an important center during the 16th and 17th centuries, when its ships traded in the Near and Middle East, carrying spices, silks, and precious woods. The advent of the steamship in the mid-19th century led to the town’s decline; and some three-quarters of its 8,000 citizens left for America, with most settling in New York. Gracing the pathway is the Palazzo Murat, originally built by Prince Joachim Murat, whom Napoleon designated as King of Naples in 1808. Murat wanted to lead a simple life, yet built a grand palazzo. He was killed in battle and never enjoyed his palace.

The majolica dome, Positano’s landmark, is that of the Chiesa Madre, or the parish church of Santa Maria Assunta. It has a green and yellow majolica dome, topped by a cupola. It was built on the site of a former Benedictine Abbey of Saint Vito, a 13th-century Romanesque structure, and was almost completely rebuilt in 1700. The church has a carved wooden Christ, a masterpiece of devotional religious art. At the altar, is a 13th-century Byzantine painting on wood with the Madonna and Child, known as the Black Virgin. Legend claims that the painting was once stolen by Saracen pirates, who, when fleeing during a raging storm, heard a voice from the heavens, say: “Posa, posa!” “Put it down, put it down.” When they placed the statue on the beach near the church the storm calmed, as did the Saracens. Positano was saved, and the town’s name was established. Others claim the town is named after the god Poseidon.

On Positano’s famous beachfront is Tre Sorelle Ristorante, and Music On The Rocks. This lively area offers great people-watching opportunities. The footpath, Via Positanesi d’America, follows the sea and connects the Spiaggia Grande with Fornillo Beach. Three Saracen towers watch its shore: the most famous ones are, La Torre Trasita, La Sponda, and Torre Di Fornillo, all from the 14th century. Set in the sea just a short distance away, are the mysterious islets of Li Galli. Legend has it that they were once mermaids and now have turned to stone.

  • Olive Oil Tasting. Join us for a tasting of our locally produced Extra Virgin Olive Oil. At Cooking Vacations we make our own first-cold pressed extra virgin olive oil from healthy olives that have been tended and cared for all summer long. We use only the first cold press of virgin olive oil. It means that the oil we bottle is pressed only one time giving it a clean fresh taste. Virgin means it is pure and not mixed with anything else. It is DOP-Denominazione di Origine Protetta, the ‘origin protected’ domain of production and “made on-site in Italy.” Grown under the warm Mediterranean sun, in rich volcanic soil, and with salt sea winds, our olives make perfect olive oil. We respect the old-world process of picking just at the right time, just in October and not too late in the season. Always organic. Our olive oil is made without chemicals or preservatives, we promise. The informal tasting provides a bit of insight into tasting, buying, and using olive oil.

This family-owned producer of ceramics also ships worldwide.


The town of Amalfi is rich in culture and history. The small town, perched on the coastline, is dominated by Amalfi’s Cathedral, and its main streets are lined with small shops and elegant bars. Merchants display their wares outside and nothing could be more pleasant than browsing through stalls of herbs and spices, artisan jewelry, shoes, beautiful handmade Amalfi paper, and local lemon specialties such as lemon soap and lemon liqueurs. Suggested is a stop in at one of the oldest and most famous pastry makers in southern Italy – dating back to the 1800’s. A look inside reveals a sweet showcase of chocolate eggplant flavored with pine nuts, liqueur, and orange; fragrant ricotta pear tarts; candied lemon and orange dragged in dark chocolate; or festive pastries of the day! Whatever you decide to order, take a seat outside in the piazza at one of the small café tables that overlook the greatest people-watching site on the Coast.

Ravello follows. This quaint town, often called the city between ‘Sea & Sky,’ is suspended high above the coast, with sweeping views that span everything from the Tyrrhenian Sea to the mountains inland.


Ravello is hailed as the ‘International City of Music’ and is known for its precious panoramic view from the gardens of Villa Cimbrone. The town is perched 350 meters over the rocky spur of the Amalfi Coast, separating the Valle del Dragone from the Valle del Regina. Today, Ravello is world-famous for its outdoor music concerts. Visit Villa Cimbrone, once the residence of Greta Garbo, wander through the lush gardens and the Terrazza Della Rosa, or stroll down the path that leads to the Terrazzo dell’Infinito (Terrace of Infinity). This natural balcony is adorned with imposing marble busts. From this unique vantage point, you can see the distant Cilento Mountains and the Licosa beyond the sparkling sea, the lush Amalfi Coast, its distinctive terraces of colorful lemon trees, and the typical whitewashed houses that cling to the rugged coastline.

Stroll along the streets and alleyways and discover little gems of churches, chapels, and noblemen’s residences. Also see the Cathedral, Villa Rufolo, San Giovanni del Tauro, and Santa Maria.
