KOS Tours

Our office is OPEN 7 days a week from 8AM to 7PM.  Phone number  -  (808) 561-2440.  After hours phone calls are often answered, so please try anytime that is convenient.  We also accept text messages.  We are finding that email is a more efficient method to communicate due to your and our busy schedules.  Our email address is HummerToursHawaii@yahoo.com.  We can complete the entire booking process by email, or telephone if you prefer.  I highly recommend that when making a reservation you make the reservation directly to KOS Tours, using our email or telephone.  Please note that the shopping cart on this website does not work .  We specialize in very small group and private tours and a shopping cart booking system for small groups has not proven to be efficient.
