The boat slips away from Athinios as the island’s high cliffs begin to glow—white villages, black volcanic rock and the open Aegean all framed by a low sun. Onboard a traditional wooden sailing boat, passengers move from the old port past the volcanic cone, the sea hissing with geothermal heat near the hot springs, and drop anchor at Thirassia’s quiet jetty where a taverna waits.

Bring reef-safe sunscreen
The hot springs and coastal ecosystem are sensitive—use reef-safe sunscreen to reduce chemical impact.
Wear water shoes
Rocky landings and slippery decks make closed-toe water shoes useful for swim exits and the taverna jetty.
Prepare for sulfur smell
Hot springs emit a sulfur odor—bring a light scarf if you’re sensitive, and don’t worry; it dissipates once you reboard.
Manage seasickness
Open Aegean stretches can be choppy—take anti-nausea medication beforehand if you’re prone to motion sickness.

Needed for swimming at the hot springs and cooling off from the sun.
