A sharp salt breeze lifts as the boat slips from Agios Sostis, the wooden bridge of Cameo shrinking behind you while Laganas Bay opens in a sheet of turquoise. Sunlight slices through a glass-bottom panel, and every ripple and reef below seems to have a personality — curious, patient, and alive.

Bring reef-safe sunscreen
Strong sun and reflective water mean high UV; use reef-safe sunscreen to protect skin and marine life.
Wear swimwear under clothes
There are brief land stops and limited changing facilities — wearing swimwear under light layers saves time.
Expect limited facilities
No toilets on the boat or Marathonisi island; use facilities before boarding and bring tissues and hand sanitizer.
Carry a small dry bag
Protect phone, camera, and wallet from spray during cave passages and swimming stops.
Swimsuit (worn under clothes)
