Authentic cruises with wooden boats (semi-private & private)
If you want a unique one-day experience on a wooden boat with swimming stops at stunning, roadless beaches, Amanda Boat and Aegeas Cruises sail with a small number of passengers (approx. 16–18) for comfort and atmosphere. The route is decided by the captain based on the weather, so the experience is always pleasant—often around western Sifnos or Polyaigos.
Both companies also offer private cruises.
Tip: Book early and allow 2–3 flexible days so they can schedule you for the best weather.
Be your own captain (no-license & licensed)
Want flexibility and your own rhythm? Calypso Boat Rentals and Sifnos BlooMarine rent boats without a license—perfect for planning your own day, exploring coves, and discovering turquoise waters and dramatic coasts around Sifnos. If you have a speedboat license, you’ll also find larger RIBs for powerful trips to nearby islands.
With skipper for comfort, timing, and “secret” spots
For those who prefer to relax and trust an experienced captain, Calypso, BlooMarine and RIB Adventures organize skipper-led excursions to selected destinations. They know the local winds, hidden coves, sea caves, and the best hours to avoid crowds.
