near San Ignacio, Belize
Bus. If you arrive at the airport, a taxi to the bus station is $25US (usually for 3 people) then a bus to San Ignacio will be about $5US, per person. This entire evolution may take much of the day. It’s inexpensive but there are other reasonable options.
Private shuttle. A private shuttle from the airport to San Ignacio can be as little as $23-35US per person and takes about an hour and forty five minutes from the time you walk out of the airport doors. Try William, email@example.com or Elias,firstname.lastname@example.org. I know them both personally and they can usually be booked for the prices mentioned. (BelizeBritt Blog)
