Adventure brief
Poseidon bluewater 170 - No License
Take the helm off Agia Kiriaki and explore Milos’s volcanic coastline at your own pace aboard the Poseidon bluewater 170. Perfect for small groups, this no-license rental gives you direct access to sea caves, white beaches and crystal Aegean water.
On the south coast of Milos, Greece, the Poseidon bluewater 170 - No License from Asterias boat rentals offers a rare kind of independence: rent a fully equipped, self-drive boat from the beach of Agia Kiriaki and set your own course around Milos’s volcanic shoreline. Choose a half day (five hours) to visit a handful of coves or opt for a full day (ten hours) to sweep farther along the island’s sculpted coast. Your experience begins at Agia Kiriaki beach.
Staff will collect ID to complete the rental agreement, guide you to the boat, and deliver a concise safety briefing and handling tutorial. The craft seats up to five people and provides comfortable seating and basic equipment for snorkeling and short swims. No formal license is required to take the helm, but all passengers must be able to swim; service animals are welcome and the operator is Blind/Deaf-friendly.
Note that the boat is not wheelchair accessible, though ambulatory wheelchair users can be accommodated. Pregnant women should not participate. What makes a self-drive day in Milos distinctive is the island’s volcanic character and the variety of coastal formations within easy reach.
The southern coastline offers sea caves, natural arches, white-sanded coves and steep, banded cliffs sculpted by wind and waves. Popular stops include Kleftiko with its cavernous channels, the collapsed-cave pocket of Sykia, the broad beaches of Fyriplaka and Tsigrado, and smaller bays such as Gerakas, Provatas, Gerontas and Kipos. Anchoring in a quiet inlet, you can jump into clear, thermally moderated Aegean water, float above hidden reefs, and swim through narrow sea caves if conditions are calm.
Practicalities shape enjoyment here: shoes are not allowed on board to protect the deck, and operators ask guests to arrive roughly ten minutes before departure to ensure prompt departures. A skipper is available for hire at €50 for a half day or €100 for a full day if you prefer not to operate the boat yourself. Return to Agia Kiriaki at your scheduled time; staff will be on hand to help dock and relieve you.
For travelers who want flexible exploration rather than a guided timetable, the Poseidon bluewater 170 provides direct access to the island’s most cinematic coastal features. Plan a route, bring reef-safe sunscreen, drinking water and a compact dry bag, and use a conservative margin for fuel and weather. With a little preparation, a self-drive rental translates Milos’s raw geology into an intimate, on-water itinerary tailored to your group.
Local operators like Asterias boat rentals keep group sizes small, which reduces crowding at fragile beaches and makes anchor spots easier to find. Consider combining a morning start with an afternoon swim stop to maximize calm seas and light for photos safely.
