Discover the Wild West Coast of Milos by Sailing Boat

The Sailing Boat Small Group Kleftiko and Sikia Cave West of Milos takes you deep into one of the Aegean's most dramatic seascapes.

With more than 75 beaches of crystal-clear, deep-blue water and multi-coloured carved rocks lining Milos's coastline, every hour on deck reveals a new spectacle. This is the definitive way to experience western Milos.

About This Tour

A Sailing Adventure Unlike Any Other in the Cyclades

Milos is one of the Cyclades' best-kept secrets, and its western coastline is its most extraordinary chapter. Formed by ancient volcanic activity, the shoreline is a gallery of towering white arches, rust-red cliffs, and sea-carved tunnels that glow in the Aegean light. This sailing tour puts you right in the middle of it all, drifting through calm turquoise waters that would be completely inaccessible by land or by larger, crowded vessels.

Kleftiko is the undisputed highlight — a labyrinth of white rock islets, underwater caves, and crystalline lagoons that once sheltered the notorious pirate John Kapsis and his crew. Snorkelling here reveals a rich underwater world of bright fish and ancient anchors. Nearby, the partially collapsed Sikia Cave creates one of nature's most theatrical light shows, with rays of sunlight dancing across the vivid blue water inside the cavern.

What truly sets this experience apart is the small group philosophy. With a strictly limited number of passengers, your skipper can anchor in quieter spots, share stories about the island's volcanic geology and pirate history, and adapt the route to the conditions of the day. Refreshments are provided on board, so all you need to do is sit back, swim, and let the spectacular scenery of Milos unfold around you at a leisurely, memorable pace.

Milos Small Group Boat Tour Everything You Need to Know

Everything you need to know before you set sail around western Milos

What to Bring & Pack

The day will be spent almost entirely outdoors on the water, so smart packing makes a real difference to your comfort. Sunscreen is absolutely essential — the reflection off the sea and the white volcanic rocks amplifies UV exposure significantly. Bring more than you think you'll need and reapply regularly throughout the day, especially after every swim. A wide-brimmed hat and UV-protective sunglasses will also save you from squinting across the brilliant Aegean surface for seven hours.

Wear a swimsuit under your clothes so you can jump in at a moment's notice when the boat anchors at Kleftiko or Sikia Cave. A light cover-up or linen shirt is useful for when you want a break from direct sun. The boat can feel cooler once it picks up speed, so a thin layer is welcome. Snorkelling equipment is provided, but if you wear prescription glasses consider a prescription mask for the best underwater visibility.

  • High-SPF sunscreen (bring plenty — reapplication is key)
  • Wide-brimmed hat and UV-blocking sunglasses
  • Swimsuit worn under clothing for quick dips
  • Light cover-up or linen shirt for sun breaks
  • Thin windproof layer for sailing between stops
  • Waterproof bag or dry bag for phone and valuables
  • Motion sickness remedy if you are sensitive to boat movement

What to Expect on the Tour

Your day begins at Adamas Port, where you'll meet your skipper and a small, friendly group of fellow travellers before boarding the sailing boat. As you leave the harbour and round the southern tip of Milos, the volcanic coastline begins its show — layers of ochre, white, and grey rock rising dramatically from the sea. Your skipper will narrate the geology and history of what you're passing, bringing the landscape vividly to life.

The centrepiece of the journey is time spent at Kleftiko, where you'll have a generous swim stop to snorkel among the rocks and explore the shallow caves at water level. The atmosphere here is unlike anywhere else in the Cyclades — cathedral-like arches, glassy water, and an eerie pirate history hanging in the salty air. After Kleftiko the boat continues to Sikia Cave for another unforgettable swimming opportunity before heading back to Adamas in the late afternoon.

  • Morning departure from Adamas Port with skipper briefing
  • Scenic sailing along the multi-coloured volcanic west coast
  • Extended snorkelling and swimming stop at Kleftiko
  • Visit to Sikia Cave with its stunning natural skylight
  • Additional hidden cove stops depending on conditions
  • Light refreshments and water served on board throughout the day
  • Return to Adamas Port in the late afternoon

Good to Know Before You Go

Booking in advance is strongly recommended, especially during July and August when availability fills quickly. The tour operates subject to sea and weather conditions; in rare cases of strong winds or rough swells the skipper may modify the route slightly for safety, but Kleftiko remains the priority destination and cancellations are very uncommon. If conditions require a full cancellation you will be offered a rebooking or a refund according to the operator's policy.

Participants should be comfortable in open water and able to swim, as the swimming stops involve entering the sea from the boat. Life jackets are available on board for anyone who wants one. The boat has a shaded canopy area, a toilet, and a ladder for easy re-boarding after swims. Children are welcome but must be supervised at all times near the water. Wear shoes you can slip off easily, as footwear is not permitted on the sailing boat's deck.

  • Book early — small group spots sell out fast in peak season
  • Arrive at Adamas Port at least 15 minutes before departure
  • Comfortable swimmers only — open-water swimming confidence required
  • Life jackets available on board for all ages
  • No hard-soled shoes on deck — slip-on sandals are ideal
  • Bring cash for any optional extras or souvenirs at the port
  • Notify the operator in advance of any medical conditions or dietary needs

Milos Small Group Boat Tour What Visitors Are Saying

★★★★★

"Kleftiko absolutely blew us away — the white rock formations rising out of crystal-clear turquoise water felt completely surreal. Our skipper knew every hidden corner and anchored perfectly so we could snorkel right inside the sea caves. The group was only eight people, which made the whole experience feel private and unhurried. Hands down the highlight of our entire trip to Greece."

"We squeezed through Sikia Cave on the tender dinghy and the bioluminescent light inside was unlike anything I've ever seen. The crew served fresh watermelon and local snacks while we floated in a secluded bay afterward — such a lovely touch. Snorkeling visibility must have been at least 15 meters; the underwater rock arches are stunning. I'd rebook this trip on our next visit without a second thought."

"Really enjoyed the sailing and the stops at Kleftiko were breathtaking — the swim time there alone is worth every euro. One bay was a bit crowded with other boats when we arrived, though our captain repositioned and found us a quieter spot quickly. The on-board snorkeling gear was in great condition and the crew was genuinely friendly and knowledgeable about the geology. Would definitely recommend this milos small group boat tour to anyone wanting a relaxed, scenic day on the water."

"From the moment we left Adamas port the vibe was perfect — good music, a cool breeze, and incredible scenery unfolding around every headland. The captain took time to explain the volcanic history of Milos while we sailed, which added so much context to what we were seeing. Swimming inside Sikia Cave felt like discovering a secret world. This small-group format is the only way to see the west coast properly; larger ferries simply can't access these spots."

FAQ

Milos Small Group Boat Tour Frequently Asked Questions

Everything you need to know before you set sail on this unforgettable voyage along Milos's dramatic western shore.

The Sailing Boat Small Group Kleftiko and Sikia Cave West of Milos tour includes a full day of sailing aboard a traditional wooden vessel with a maximum of roughly 10 passengers. Snorkeling equipment — masks, fins, and vests — is provided for all guests at no extra charge. A light lunch or snack spread with seasonal fruit, local cheese, bread, and soft drinks is served on board. Entry into Sikia Cave via the tender dinghy is included in the itinerary, weather and sea conditions permitting. Alcoholic beverages and personal expenses are not covered.
Departure is from Adamas port, the main harbor of Milos, usually between 09:00 and 10:00 in the morning — your confirmation email will give the exact meeting time. The full excursion lasts approximately 7 to 8 hours, returning to Adamas in the late afternoon. Guests are asked to arrive at the dock at least 15 minutes before the scheduled departure to allow for a smooth boarding process. The return time can vary slightly depending on wind and sea conditions, so it's wise not to book a same-day evening ferry off the island.
Absolutely — non-swimmers are very welcome on board and can enjoy the stunning scenery, volcanic cliffs, and crystal-clear water from the deck. Life jackets are available, and the crew keeps a close eye on everyone in the water. Snorkeling is optional, not mandatory, so you can simply relax on the boat or wade in shallow areas near the anchor spots. If you are a nervous swimmer, let the crew know when you board and they will make sure you feel comfortable throughout the day.
Sikia Cave is accessed through a low sea-level opening using the boat's small dinghy, which means entry is only possible when the swell is calm enough to do so safely. On most summer days conditions are ideal, but the captain has final authority over whether the cave entrance is safe. If the cave is inaccessible due to waves, the itinerary is adjusted and an alternative scenic bay is visited instead — the coastline offers plenty of spectacular alternatives. No refund is given for cave entry specifically, but the overall tour experience remains outstanding regardless.
This is a genuine milos small group boat tour, capped at around 10 guests, which is what sets it apart from the larger catamaran day trips that carry 30 to 50 people. With fewer passengers the boat can anchor in narrower coves, everyone gets ample swim time without crowding, and the crew can give personal attention to each guest. The intimate atmosphere also means you can chat with the skipper, ask questions, and tailor the pace of the day a little more freely. If you want a relaxed, personalized sailing experience rather than a party-boat atmosphere, this size is perfect.
Pack light — sunscreen (reef-safe if possible), a hat, sunglasses, a swimsuit (or two!), a light cover-up for the sail back, and a small towel are the essentials. Water shoes are handy for rocky shore landings but not strictly necessary. Leave large suitcases, valuables, and anything you'd be heartbroken to lose to the sea back at your hotel, as storage on a sailing vessel is limited. Cash for any extras or tips for the crew is always appreciated. Motion-sickness tablets are worth taking beforehand if you are prone to seasickness, especially on windier days.
