Exploring Nisyros by Boat: A Volcanic Day with Beaches and BBQ
This boat trip to Nisyros-Mandraki offers a full day of adventure, perfect for those who love a mix of natural wonders, authentic Greek village life, and good food. The highlight is undoubtedly visiting Nisyros’ volcanic caldera, the largest in Europe, which promises a fascinating walk into the world’s only active volcano crater accessible to visitors. As you sail from Kos, you’ll enjoy the scenic views of the Aegean, and once ashore, there’s plenty of time to relax on the island’s beaches or wander around charming Mandraki.
Two features I particularly appreciate are the guided visit into the volcanic crater—a surreal experience—and the delicious BBQ lunch at Agios Antonios that perfectly combines local flavors with a laid-back atmosphere. However, a possible drawback is that the tour’s duration is quite packed, and if you’re not a strong swimmer or prone to seasickness, you might find the boat ride less comfortable. Still, with proper planning, this trip offers a well-balanced mix of nature, culture, and leisure.

Discovering Nisyros: The Volcano Island’s Unique Charm

This experience is a fantastic way to see a lesser-known Greek island that packs a punch with its natural drama. The boat departs from Kos, a popular starting point, and the trip lasts around 10 hours, including transfers and free time. The highlight is the visit to the volcanic crater in Nisyros, which is an active caldera measuring about 4 km in diameter—the biggest in Europe. Standing at the edge, you’re greeted with steam vents and yellow sulfur crystals, a strange but beautiful reminder of the island’s fiery past.
I love how the tour balances the thrill of exploring a volcanic site with the chance to unwind. Descending into the crater feels like stepping onto another planet—something I’ve never experienced on a Greek island before—and the steam rising from the earth adds a touch of the primal. The guidance by knowledgeable escorts like the tour guides ensures you understand what you’re seeing; some reviews mention the friendly and informative nature of the guides, which makes the journey even more engaging.
