Pick the trip by destination, then check the departure port. The Nisyros volcano trip is the only major one that leaves from Kardamaina’s own harbour; others leave from Kos town, about a 30 to 40 minute drive away, and often include a hotel pickup.

Are boat trips suitable for children?
Many are. Look for trips that mention family activities, shade on deck and swimming stops. Check any age rules and whether life jackets are provided.
Do boats run in winter?
Mostly no. The main season is about May to October. Outside that time, schedules are limited.

Swimwear, a towel, sun protection, a hat, water and a light layer. Bring cash for extras on board or on the islands.
