Philip S. Goldson Airport is the International Airport of Belize.
Once you land in Belize City, you can get to Ambergris Caye by air or by boat.
If you are weary of flying in small aircraft than I suggest taking the Belize Express - it is a 1.5 hour ferry from Belize City to Ambergris Caye. Our driver in Belize City would transfer you from the Airport to the Ferry Terminal at an additional cost, however transfers upon arrival/departure from the San Pedro Ferry Terminal and San Pedro Airport to your Villa is complimentary.
If you are totally fine with the flight, I highly suggest flying as it is a breathtaking 15 minute flight over the Barrier Reef and many Guests have stated it to be one of the highlights of their trip.
