Milos Kleftiko Boat Tour Everything You Need to Know

Plan your half-day on the water with these essential tips and insights

What to Bring on Your Kleftiko Boat Tour

Packing light but smart is the key to a comfortable half-day on the water. The boat provides shade, but the Aegean sun is powerful — sun protection is non-negotiable. Wear your swimsuit under your clothes so you are ready to jump in at Kleftiko and Gerakas bay without any fuss. A small dry bag is handy for keeping valuables safe while you swim in the crystal-clear waters around the rock formations.

Footwear worth thinking about: the volcanic rocks at Kleftiko can be sharp, so water shoes or reef sandals will make exploring the caves far more comfortable. Snorkelling gear is worth bringing if you have it, as the underwater scenery around Kleftiko is spectacular. The crew provides refreshments on board, so you don't need to load up on food, but a small snack for before departure never hurts if you tend to get hungry early.

  • Sunscreen SPF 30+ and a hat
  • Swimsuit worn underneath clothing
  • Water shoes or reef sandals
  • Small dry bag for phone and valuables
  • Snorkelling mask and fins (optional but recommended)
  • Light cover-up or sarong for the return trip
  • Cash for optional transfer service or tips

What to Expect During the Tour

The experience begins at Agia Kiriaki beach on Milos's southern coast, where you'll board the boat and meet your crew. The atmosphere is relaxed and welcoming from the moment you step on board. As you leave the shore, the landscape quickly shifts to dramatic open-water scenery, with volcanic cliffs rising from the sea on all sides. The crew will share stories about the area's geology and history as you cruise toward the main destination.

Arriving at Kleftiko feels like sailing into a natural amphitheatre. The towering white rock arches and caves are best appreciated from the water, and there is ample time to swim, snorkel, and photograph the scenery. After Kleftiko, the boat moves on to Gerakas bay, a quieter and more sheltered spot perfect for a final swim before heading back. Throughout the journey, the crew serves refreshments and homemade bites, keeping the mood festive and distinctly Greek.

  • Board at Agia Kiriaki beach and meet the crew

★★★★★

"Absolutely breathtaking experience from start to finish. Our captain navigated us right into the sea caves at Kleftiko and we spent nearly an hour snorkeling the crystal-clear turquoise waters. The small group size meant we never felt rushed or crowded, and the crew was incredibly knowledgeable about the island's geology and pirate history. Easily the best half-day we spent in all of Greece."

★★★★★

"I've done boat tours all over the Mediterranean and this one genuinely stands out. The catamaran was spotless and well-equipped, and the crew made sure everyone had snorkeling gear that actually fit. Kleftiko itself is unlike anything I've ever seen — towering white volcanic rock formations rising straight out of the sea. We also stopped at a quiet cove on the way back that was completely deserted, which felt like a real hidden gem."

"Really lovely half-day out on the water visiting Kleftiko — the scenery is genuinely jaw-dropping and worth every cent. The snorkeling stop was a highlight and the light lunch provided was a nice touch. I'm giving four stars only because the morning departure felt a little rushed getting everyone on board, but once we set off everything was smooth and well-organised. Would absolutely recommend it to anyone visiting Milos."

"We booked the Milos Half-day Tour to Kleftiko as a couple and it exceeded every expectation. The crew were friendly, funny, and clearly passionate about showing visitors the best of the island. Swimming inside the sea caves with sunlight filtering through the rock arches is something I will never forget. If you are visiting Milos, do not leave without doing this trip — it is simply unmissable."
