You can take a bus from many cities, including Guatemala City or Antigua, into Xela. While the local buses (nicknamed "Chicken Buses" by visiting Yanquis), which are brightly painted old school buses, take these routes, they are long, bumpy, noisy and crowded, however they are cheaper (between Q.20 and Q.35 depending on the route).
