A half-day catamaran (roughly 09:30-14:30) that swims and snorkels the empty turquoise coves of uninhabited Rhenia, sails scenically past Delos with captain commentary, and serves a cooked lunch on deck. Semi-private (small group) keeps the deep-blue Cycladic sailing-day feeling that no land tour delivers, with port pickup included. This is the quintessential Greek-islands-on-the-water day if you'd rather sail and swim than walk ruins.
What to expect
You'll board a semi-private catamaran at 09:30 for a half-day sailing adventure across the Cycladic waters. The boat glides scenically past the ancient ruins of Delos while the captain shares its history, then anchors in the turquoise coves of uninhabited Rhenia for swimming and snorkeling in crystalline water—far from the crowds at Mykonos's shore beaches. Around midday, the crew serves a cooked lunch on deck as you sail back, giving you the deep-blue Greek-islands-on-the-water experience that land tours simply cannot match. You'll return to port by 14:30, having swum pristine waters and absorbed the rhythm of a traditional sailing day.
The ship's South Coast Cruise is $147 and stays on the south beaches; this direct semi-private adds Rhenia swimming and a Delos sail-by for ~$130 -- about $17 cheaper with more inclusions. Confirm lunch/open-bar specifics by email, since the site lists them per-boat. Direct wins on both price and access.
Good to know
Departure is 09:30, so plan port pickup from the pier (transfer included) with a buffer of at least 30 minutes before departure to reach the operator's location in Mykonos town. The half-day duration wraps by 14:30, giving you a 6–8 hour window and a comfortable margin before the ship's all-aboard; confirm exact return time with the operator. Bring swimwear, a towel, sunscreen, and water shoes for rocky cove entry; a waterproof bag for valuables is practical since you'll be in the water. Email Mykonos Dolphin directly to verify the specifics of lunch and any open-bar inclusions, as these details vary by boat size (Lagoon 38/40 at €120 or Lagoon 44 at €140 per person).
