Coming from Santiago de los Caballeros

Follow the street leading into Mao until the first traffic light. There turn right and follow the street until you reach its end, where you find the Fortaleza, a big green building. There turn right again. Stay on that street for a while until you get to the prison, a huge white complex with watchtowers. Just after it there is the drive to the territory of Biotropic on the right-hand side. It is marked by a big escutcheon. Pass the sentry and keep going straight until you get to the parking lot.

 

Coming from Santiago de Rodriguez

Follow the street leading to Mao until you come to a crotch with a filling station with a big Dominican flag. There head towards Mao but immediately after the crotch there is the drive of Biotropic on the left.
