Discover the volcanic charm of Nisyros with a full-day boat trip from Kos, including swimming, sightseeing, and a delicious Greek BBQ. A mix of adventure and relaxation.

This boat trip offers a compelling way to experience the volcanic island of Nisyros from Kos. In around ten hours, travelers can expect to explore Greece’s largest volcanic caldera, enjoy a swim on scenic beaches, and indulge in a hearty Greek BBQ—all with convenient hotel transfers included.
What we really appreciate about this experience is its blend of natural wonder and laid-back island charm. Visiting the volcano’s crater and walking through Mandraki’s quaint streets provides a slice of authentic Greek island life. That said, it’s worth noting that the tour is quite a long day, and the boat trip might not suit those prone to seasickness or seeking a more leisurely pace.
This tour suits those craving a mix of adventure, stunning landscapes, and cultural relaxation. Whether you’re a nature lover eager to see Europe’s biggest volcanic caldera or a sun-seeker wanting time on beautiful beaches, this trip delivers a well-rounded experience.

Looking for more options in Mandraki? Here are some other experiences worth considering.

Starting with easy hotel pickup, we appreciated that the tour company handles all the logistics, so you can focus on enjoying your day. The air-conditioned bus rides across Kos are comfortable and set the tone for a smooth journey. Once on the boat, the atmosphere is relaxed but lively, with plenty of space to settle in and enjoy the views.
The boat itself is well-equipped, and while some reviews mention it’s best suited for those not prone to seasickness, the crew does their best to keep everyone comfortable. The marine ride is about an hour, during which you’ll get glimpses of the Aegean’s sparkling waters, with many passengers taking photos of the coastline.

The highlight of the trip is undoubtedly the visit to Nisyros’ volcanic caldera—a sight that truly impresses. At about 4 km in diameter, this caldera is the largest in Europe, and walking into its crater feels like stepping onto a different planet. The sulfuric fumes and the yellow crystal formations make it feel alive and active, adding a layer of raw nature to the experience.
One reviewer mentions that “the massive crater and the steam escaping from holes” added a sense of awe. Descending into the crater is a highlight; you can actually walk into the volcanic landscape, with pathways leading visitors to viewpoints overlooking the bubbling depths below. The sulfur crystals, with their striking yellow color, are a photographer’s dream.
However, a few mention that the terrain can be uneven and a bit challenging for those with mobility issues. It’s also worth noting that climbing into the crater isn’t recommended for individuals with asthma, due to the sulfur fumes.
After the volcanic exploration, about an hour is allotted for free time in Mandraki. This charming village has a handful of shops, cafes, and a historic monastery, offering a taste of local Greek island life. Walking through its narrow streets, you might find handmade souvenirs or enjoy a coffee with a view.
One tourist noted, “The monastery was peaceful and beautiful, and I loved wandering around the small shops.” It’s a gentle contrast to the volcanic activity, ideal for those wanting a slower pace or some cultural insight.
Keep in mind, the free time is limited, so if you want to explore more thoroughly, plan accordingly. Also, the layout is compact, making it a manageable stroll for most.

Lunchtime is a real treat with a delicious Greek BBQ served at Agios Antonios. The meal features tender pork and chicken souvlaki, paired with fresh Greek salads, tzatziki, and bread. The food is described as hearty, flavorful, and generous—perfect after some active exploration and a great way to fuel the rest of your day.
Some reviewers mention that the BBQ is well-prepared and embodies authentic Greek flavors, which enhances the overall value of the trip. It’s a simple yet satisfying meal that provides a true taste of local cuisine without breaking the bank.
Following lunch, the tour allows plenty of time for swimming on Nisyros’ gorgeous beaches. The waters are clear, inviting, and perfect for a refreshing dip or just soaking up the sun. The beaches are described as beautiful and peaceful, ideal for unwinding after the morning’s adventure.
A common theme among reviews is how relaxing and scenic the beaches are, with some travelers mentioning that they enjoyed lounging on the sand and taking in the views of the island’s volcanic landscape from the shoreline.

The return boat trip follows the same relaxed rhythm, giving everyone a chance to soak in the scenery once more. The bus ride back to Kos is comfortable, and the entire day wraps up with hotel drop-offs, making it a seamless experience.
While the tour is packed into a single day, it balances activity with downtime, allowing travelers to enjoy the highlights without feeling rushed. The inclusion of lunch and transfers enhances the overall value, especially for those who prefer a hassle-free day of exploration.

This Nisyros boat trip offers a well-rounded package for travelers looking to combine natural wonders with cultural sights and beach relaxation. It’s particularly suited for those eager to see Europe’s largest volcanic caldera, enjoy authentic Greek cuisine, and spend time unwinding on scenic beaches. The guided aspect adds educational value, making it ideal for curious travelers keen to learn about the island’s volcanic history.
However, it is best suited for those comfortable on boats and able to handle a relatively long day, as the total duration is around 10 hours. If seasickness is a concern or mobility is limited, it’s worth considering alternative ways to experience Nisyros. Also, the tour’s focus on sightseeing means it’s less suitable for travelers seeking a slow, leisure-only day.
This tour offers excellent value for those who want a snapshot of Nisyros’ volcanic majesty combined with relaxing beach time and delicious food, all while enjoying the ease of organized transfers and guided insights.
