Best Sea Kayaking Routes in Naples: Posillipo & Gaiola

Paddling along the Posillipo coastline is easily one of the most rewarding outdoor experiences in Southern Italy. From ancient Roman underwater archaeology to secluded sea caves and breathtaking views of Mount Vesuvius, severe traffic and crowded streets fade away the moment your paddle dips into the Tyrrhenian Sea. Here is your ultimate guide to the best sea kayaking routes in Naples, covering the iconic Posillipo peninsula and the protected Gaiola Underwater Park.

1. Route 1: The Historic Coastal Line (Riva Fiorita to Palazzo Donn’Anna)

• 

Distance: ~4 km round-trip | Duration: 2 Hours | Difficulty: Easy

Starting from the sheltered harbor of Riva Fiorita—right below the historic Villa Volpicelli—this route takes you past some of the most grand and storied waterfront architecture in Naples. As you paddle north towards Mergellina, you will skim past cliffside estates like Villa Lauro and Villa Roccaromana, where natural caves and hidden inlets amaze visitors.

The crown jewel of this stretch is arriving at the majestic, unfinished Palazzo Donn’Anna. Seeing its 17th-century volcanic tuff arches rise dramatically from sea level offers a perspective that walking tours simply cannot replicate.

• Must-See Highlights: Secret tuff caves, snorkeling at Villa Lauro to observe underwater volcanic emissions with bubbles rising from the seabed, and stunning photo spots beneath Palazzo Donn’Anna.
• Pro Tip: Stop at Spiaggetta delle Monache for a quick swimming break before paddling back.

Launching from the picturesque fishing village of Marechiaro, route west past the famous Fenestrella ‘e Marechiaro towards the twin islets of Gaiola, connected by a narrow suspended bridge.

Below your kayak lies a submerged world of 2,000-year-old Roman fish ponds (piscinae), porticos, and ruins belonging to the ancient Villa Imperialis of Vedius Pollio. Just beyond Gaiola lies the dramatic amphitheater of Trentaremi Bay, where soaring yellow tuff cliffs drop vertically into crystal-clear turquoise waters.
