Traveling between Greek islands offers a chance to see some of the most captivating landscapes and charming villages in the Cyclades. One of the more popular options for exploring Milos from Sifnos is a full-day speedboat tour that promises swimming, snorkeling, and plenty of scenic moments. While I haven’t personally taken this exact trip, I’ve gathered enough info to give you a thorough rundown—helping you decide if it’s the right adventure for your Greek itinerary.
What immediately draws us to this experience is the chance to cruise along the coast in a small, intimate group, which often translates into more personalized attention and fewer crowds. Plus, the opportunity to swim in crystal-clear waters and discover hidden beaches like Gerakas and Sarakiniko is truly appealing. On the flip side, one thing to keep in mind is that this is a long day on the water, so it’s best suited for those comfortable with boat travel and looking for a mix of adventure and relaxation.
This tour mainly suits travelers who love outdoor activities, scenic coastal views, and exploring less-visited spots, rather than those expecting a laid-back, sightseeing-only experience. If you’re all about active days full of swimming and photography, this could be a highlight of your trip. Now, let’s dig into why this trip might work for you—and what to keep in mind.
