We advise that you book at least 3-4 days prior to your actual departure from Kos island. By doing so, you will have the opportunity to reschedule your cruise, should we need to do so, due to unfavorable weather conditions. This sometimes does occur during the summer months. This suggestion is for you not to miss out on the fun! To book your boat tour with us, you can use our booking form, whatsapp us, call us or email us directly. We will be happy to hear from you and have you sailing with us on your next Kos visit!
