Short boat runs and two guided dives expose Symi’s clear Aegean waters: cavern walls, WWII wrecks and turtle-studded bays. Ideal for certified divers who want a concentrated mix of history, visibility and varied underwater terrain.
More ways to explore the area's outdoor wonders
You step off the stern and the Aegean takes the weight of the day; the boat eases away from Gialos harbor and the sea opens, clear enough to read the bottom. Salt lifts into the air, the skipper points to a crag where the first descent will begin — a cavern shelf or a WWII E-boat lying quiet beneath blue light.
