The engine cuts through Aegean blue and the island cliffs rise like a challenge — by the time the speedboat threads a narrow channel, Kastri rock and the little white chapel used in Mamma Mia appear, perched on a stone plinth above the sea.

The engine cuts through Aegean blue and the island cliffs rise like a challenge — by the time the speedboat threads a narrow channel, Kastri rock and the little white chapel used in Mamma Mia appear, perched on a stone plinth above the sea.
Climbing the 110 carved steps is part pilgrimage, part film-set curiosity: a narrow path hewn into limestone that reveals the chapel’s simple façade and sweeping views across the Sporades. The coastline here records a geological dialogue of uplifted marble and softer limestone, sculpted by wind and wave, creating small coves and steep rock spines where the boat can slip in for swims.
Culturally, the chapel is more recent fame than ancient shrine — its cinematic notoriety brought visitors, but the local islands remain fishing and olive-farming communities with a slow rhythm. Your stop list typically includes St Ioannis, Spilia, Mavraki and Keramoto — small beaches where the sea dares you into transparent water and calms you with warm currents.
Practical guidance: tours run about three hours and are suitable for most fitness levels, but the chapel’s 110 steps are steep and uneven; wear closed shoes for the climb and a swimsuit for quick swims. Bring sun protection and a light wind layer — sea spray and open-boat exposure cool fast. Expect basic facilities: bottled water is provided, but food is minimal, so carry snacks if you need them.
Timing matters: mornings offer calmer seas and softer light for photos; late afternoon can be breezy. Respect the site — stick to paths, avoid climbing on fragile rock, and pack out any trash to keep these small islands wild and welcoming.
Most bookings depart from Skiathos harbor or designated piers in Skiathos Town; check your confirmation for the exact meeting point.
Yes—infants must sit on an adult’s lap; the tour is described as suitable for all fitness levels, but consider the steps when bringing small children.
Yes—itineraries include stops at small beaches like Spilia and Mavraki where you can swim directly from the boat; bring swimwear and a towel.
