A friend and I are staying Bogota, and would like to do a day trip to Laguna de Guatavita if possible. We understand we can get a bus from Portal del Norte to Guatavita or Sesquilé, from which we may be able to get transport to the lake. We are hoping to do this and get back to Bogota within a day, and not spend a night in one of the towns. But I’m reading that it may be more difficult to do this on a weekday (our schedule means it’ll probably need to be Monday if we do it). Does this seem possible? Would it be better to try from Guatavita or Sesquilé? Does anyone know what time the busses back to Bogota stop running?
